+   <prologue>This schema is a Hierarchical Event Descriptors (HED) Library Schema implementation of Standardized Computer-based Organized Reporting of EEG (SCORE)(1-2) for describing events occurring during neuroimaging time series recordings.
+The HED-SCORE library schema allows the annotation of electrophysiology recordings using terms from an internationally accepted set of defined terms (SCORE) compatible with the HED framework .
+The resulting annotations are understandable to clinicians and directly usable in computer analysis.

+            <description>Rhythmic activity occurring during wakefulness over the posterior regions of the head, generally with maximum amplitudes over the occipital areas. Amplitude varies. Best seen with eyes closed and during physical relaxation and relative mental inactivity. Blocked or attenuated by attention, especially visual, and mental effort. In adults this is the alpha rhythm, and the frequency is 8 to 13 Hz. However the frequency can be higher or lower than this range (often a supra or sub harmonic of alpha frequency) and is called alpha variant rhythm (fast and slow alpha variant rhythm). In children, the normal range of the frequency of the posterior dominant rhythm is age-dependant. (Source: Beniczky ea 2013, Appendix S2; suggested tags from Beniczky ea 2017, Table 4.)</description>

+            <description>EEG rhythm at 7-11 Hz composed of arch-shaped waves occurring over the central or centro-parietal regions of the scalp during wakefulness. Amplitudes varies but is mostly below 50 microV. Blocked or attenuated most clearly by contralateral movement, thought of movement, readiness to move or tactile stimulation.

+               <description>A seizure of unknown onset may still evidence certain defining motor (e.g., tonic clonic) or nonmotor (e.g., behavior arrest) characteristics. With further information or future observed seizures, a reclassification of unknown-onset seizures into focal or generalized-onset categories may become possible. Therefore, “unknown-onset” is not a characteristic of the seizure, but a convenient placeholder for our ignorance.

Episodes usually occur in the first third of the night during slow wave sleep. Polysomnographic recordings demonstrate 2 abnormalities during the first sleep cycle: frequent, brief, non-behavioral EEG-defined arousals prior to the somnambulistic episode and abnormally low gamma (0.75-2.0 Hz) EEG power on spectral analysis, correlating with high-voltage (hyper-synchronic gamma) waves lasting 10 to 15 s occurring just prior to the movement. This is followed by stage I NREM sleep, and there is no evidence of complete awakening. (Source: Beniczky ea 2017, Table 9; Beniczky ea 2013, Appendix S5.)</description>

+                  <description>Self-sustaining: Generalized PPR continuing after stimulation. This may not be demonstrated unless the stimulus train is terminated as soon as a generalized PPR is identified. It was termed prolonged photoconvulsive response by Reilly and Peters, and has a strong association with epilepsy and visually induced seizures in patients referred for clinical EEG examination. Its prevalence in asymptomatic general populations is unknown, but was found in five of 13,658 apparently healthy aircrew by Gregory et al.

+                  <description>Rarely, photic stimulation may activate an epileptogenic cortex, which is also spontaneously active; IPS could then also elicit a seizure by stimulating this, usually posterior located, area. It is questionable whether this should be considered a photoparoxysmal response (PPR), and it does not figure in established classifications.

+               <description>Seizure semiology refers to the clinical signs and sympoms that are observed during a seizure. Semiology is described according to the ILAE Glossary of Descriptive Terminology for Ictal Semiology (Blume et al., 2001). Besides the name, the semiologic feature can also be characterized by the somatotopic modifier, laterality, body part and centricity. Uses Location-property tags.

+            <description>Bilateral, diffuse slowing of brain signals during hyperventilation. Recorded in 70 percent of normal children (3-5 years) and less then 10 percent of adults. Slowing usually appears in the posterior regions and spreads forward in younger age groups, whereas slowing tends to appear in the frontal regions and spreads backward in the older age group.

+            <description>Physiologic response consisting of rhythmic activity elicited over the posterior regions of the head by repetitive photic stimulation at frequencies of about 5-30 Hz. Comments: term should be limited to activity time-locked to the stimulus and of frequency identical or harmonically related to the stimulus frequency. Photic driving should be distinguished from the visual evoked potentials elicited by isolated flashes of light or flashes repeated at very low frequency.

+            <description>A response to intermittent photic stimulation characterized by the appearance in the record of brief, repetitive muscular artifacts (spikes) over the anterior regions of the head. These often increase gradually in amplitude as stimuli are continued and cease promptly when the stimulus is withdrawn. Comment: this response is frequently associated with flutter of the eyelids and vertical oscillations of the eyeballs and sometimes with discrete jerking mostly involving the musculature of the face and head. (Preferred to synonym: photo-myoclonic response). (Source: Beniczky ea 2013; Appendix S6, Beniczky ea 2017, Table 14.)</description>

Small Sharp Spikes (SSS) of very short duration and low amplitude, often followed by a small theta wave, occurring in the temporal regions during drowsiness and light sleep. They occur on one or both sides (often asynchronously). The main negative and positive components are of about equally spiky character. Rarely seen in children, they are seen most often in adults and the elderly. Two thirds of the patients have a history of epileptic seizures.

It consists of a mixture of frequencies, often predominant in the theta range. The onset may be fairly abrupt with widespread sharp rhythmical theta and occasionally with delta activity. As to the spatial distribution, a maximum of this discharge is usually found over the centroparietal region and especially over the vertex. It may resemble a seizure discharge but is not accompanied by any clinical signs or symptoms. (Source: Beniczky ea 2013, Appendix S6; Beniczky ea 2017, Table 14.)</description>

Frontalis and temporalis muscles (e.g. clenching of jaw muscles) are common causes. Generally, the potentials generated in the muscles are of shorter duration than those generated in the brain. The frequency components are usually beyond 30-50 Hz, and the bursts are arrhythmic.</description>

In EEG, this causes positive potentials (50-100 micro V) with bi-frontal distribution, maximum at Fp1 and Fp2, when the eyeball rotates upward. The downward rotation of the eyeball is associated with the negative deflection. The time course of the deflections is similar to the time course of the eyeball movement.</description>

+                     <description>Artifact from tongue movement (Glossokinetic). The tongue functions as a dipole, with the tip negative with respect to the base. In EEG, the artifact produced by the tongue has a broad potential field that drops from frontal to occipital areas, although it is less steep than that produced by eye movement artifacts. The amplitude of the potentials is greater inferiorly than in parasagittal regions; the frequency is variable but usually in the delta range. Chewing and sucking can produce similar artifacts.</description>

+   <epilogue>The Standardized Computer-based Organized Reporting of EEG (SCORE) is a standard terminology for scalp EEG data assessment designed for use in clinical practice that may also be used for research purposes.
+The SCORE standard defines terms for describing phenomena observed in scalp EEG data. It is also potentially applicable (with some suitable extensions) to EEG recorded in critical care and neonatal settings.
+The SCORE standard received European consensus and has been endorsed by the European Chapter of the International Federation of Clinical Neurophysiology (IFCN) and the International League Against Epilepsy (ILAE) Commission on European Affairs.
+A second revised and extended version of SCORE achieved international consensus.

-'''Prologue'''
-This schema is a Hierarchical Event Descriptors (HED) Library Schema implementation of Standardized Computer-based Organized Reporting of EEG (SCORE)[1,2] for describing events occurring during neuroimaging time series recordings.
-The HED-SCORE library schema allows neurologists, neurophysiologists, and brain researchers to annotate electrophysiology recordings using terms from an internationally accepted set of defined terms (SCORE) compatible with the HED framework.
-The resulting annotations are understandable to clinicians and directly usable in computer analysis.
-
-Future extensions may be implemented in the HED-SCORE library schema.
-For more information see https://hed-schema-library.readthedocs.io/en/latest/index.html.

Eyelid myoclonia can be associated with absences, but also can be motor seizures without a corresponding absence, making them difficult to categorize. The 2017 classification groups them with nonmotor (absence) seizures, which may seem counterintuitive, but the myoclonia in this instance is meant to link with absence, rather than with nonmotor.

-The Standardized Computer-based Organized Reporting of EEG (SCORE) is a standard terminology for scalp EEG data assessment designed for use in clinical practice that may also be used for research purposes.
-The SCORE standard defines terms for describing phenomena observed in scalp EEG data. It is also potentially applicable (with some suitable extensions) to EEG recorded in critical care and neonatal settings.
-The SCORE standard received European consensus and has been endorsed by the European Chapter of the International Federation of Clinical Neurophysiology (IFCN) and the International League Against Epilepsy (ILAE) Commission on European Affairs.
-A second revised and extended version of SCORE achieved international consensus.

-'''Prologue'''
-This schema is a Hierarchical Event Descriptors (HED) Library Schema implementation of Standardized Computer-based Organized Reporting of EEG (SCORE)[1,2] for describing events occurring during neuroimaging time series recordings.
-The HED-SCORE library schema allows neurologists, neurophysiologists, and brain researchers to annotate electrophysiology recordings using terms from an internationally accepted set of defined terms (SCORE) compatible with the HED framework.
-The resulting annotations are understandable to clinicians and directly usable in computer analysis.
-
-Future extensions may be implemented in the HED-SCORE library schema.

-'''Epilogue'''
-The Standardized Computer-based Organized Reporting of EEG (SCORE) is a standard terminology for scalp EEG data assessment designed for use in clinical practice that may also be used for research purposes.
-The SCORE standard defines terms for describing phenomena observed in scalp EEG data. It is also potentially applicable (with some suitable extensions) to EEG recorded in critical care and neonatal settings.
-The SCORE standard received European consensus and has been endorsed by the European Chapter of the International Federation of Clinical Neurophysiology (IFCN) and the International League Against Epilepsy (ILAE) Commission on European Affairs.
-A second revised and extended version of SCORE achieved international consensus.

+'''Prologue'''
+This schema is a Hierarchical Event Descriptors (HED) Library Schema implementation of Standardized Computer-based Organized Reporting of EEG (SCORE)[1,2] for describing events occurring during neuroimaging time series recordings.
+The HED-SCORE library schema allows neurologists, neurophysiologists, and brain researchers to annotate electrophysiology recordings using terms from an internationally accepted set of defined terms (SCORE) compatible with the HED framework.
+The resulting annotations are understandable to clinicians and directly usable in computer analysis.
+
+Future extensions may be implemented in the HED-SCORE library schema.
+For more information see https://hed-schema-library.readthedocs.io/en/latest/index.html.

Definition from ILAE 2017 Classification of Seizure Types Expanded Version]</nowiki>
+*** Absence-seizure <nowiki>{inLibrary=score} [Absence seizures present with a sudden cessation of activity and awareness. Absence seizures tend to occur in younger age groups, have more sudden start and termination, and they usually display less complex automatisms than do focal seizures with impaired awareness, but the distinctions are not absolute. EEG information may be required for accurate classification. Definition from ILAE 2017 Classification of Seizure Types Expanded Version]</nowiki>
+**** Typical-absence-seizure <nowiki>{inLibrary=score} [A sudden onset, interruption of ongoing activities, a blank stare, possibly a brief upward deviation of the eyes. Usually the patient will be unresponsive when spoken to. Duration is a few seconds to half a minute with very rapid recovery. Although not always available, an EEG would show generalized epileptiform discharges during the event. An absence seizure is by definition a seizure of generalized onset. The word is not synonymous with a blank stare, which also can be encountered with focal onset seizures. Definition from ILAE 2017 Classification of Seizure Types Expanded Version]</nowiki>
+**** Atypical-absence-seizure <nowiki>{inLibrary=score} [An absence seizure with changes in tone that are more pronounced than in typical absence or the onset and/or cessation is not abrupt, often associated with slow, irregular, generalized spike-wave activity. Definition from ILAE 2017 Classification of Seizure Types Expanded Version]</nowiki>
+**** Myoclonic-absence-seizure <nowiki>{inLibrary=score} [A myoclonic absence seizure refers to an absence seizure with rhythmic three-per-second myoclonic movements, causing ratcheting abduction of the upper limbs leading to progressive arm elevation, and associated with three-per-second generalized spike-wave discharges. Duration is typically 10 to 60 s. Impairment of consciousness may not be obvious. Definition from ILAE 2017 Classification of Seizure Types Expanded Version]</nowiki>
+**** Eyelid-myoclonia-absence-seizure <nowiki>{inLibrary=score} [Eyelid myoclonia are myoclonic jerks of the eyelids and upward deviation of the eyes, often precipitated by closing the eyes or by light. Eyelid myoclonia can be associated with absences, but also can be motor seizures without a corresponding absence, making them difficult to categorize. The 2017 classification groups them with nonmotor (absence) seizures, which may seem counterintuitive, but the myoclonia in this instance is meant to link with absence, rather than with nonmotor.

In other words, seizure semiology describes the physical manifestations of a seizure. Semiology is described according to the ILAE Glossary of Descriptive Terminology for Ictal Semiology (Blume et al., 2001). Besides the name, the semiologic finding can also be characterized by the somatotopic modifier, laterality, body part and centricity. Uses Location-property tags.]</nowiki>

+* allowedCharacter <nowiki>{valueClassProperty} [A schema attribute of value classes specifying a special character that is allowed in expressing the value of a placeholder. Normally the allowed characters are listed individually. However, the word letters designates the upper and lower case alphabetic characters and the word digits designates the digits 0-9. The word blank designates the blank character.]</nowiki>
+* conversionFactor <nowiki>{unitProperty, unitModifierProperty} [The multiplicative factor to multiply these units to convert to default units.]</nowiki>
+* deprecatedFrom <nowiki>{elementProperty} [Indicates that this element is deprecated. The value of the attribute is the latest schema version in which the element appeared in undeprecated form.]</nowiki>
+* defaultUnits <nowiki>{unitClassProperty} [A schema attribute of unit classes specifying the default units to use if the placeholder has a unit class but the substituted value has no units.]</nowiki>
+* extensionAllowed <nowiki>{boolProperty, nodeProperty, isInheritedProperty} [A schema attribute indicating that users can add unlimited levels of child nodes under this tag. This tag is propagated to child nodes with the exception of the hashtag placeholders.]</nowiki>
+* inLibrary <nowiki>{elementProperty} [Indicates this schema element came from the named library schema, not the standard schema. This attribute is added by tools when a library schema is merged into its partnered standard schema.]</nowiki>
+* recommended <nowiki>{boolProperty, nodeProperty} [A schema attribute indicating that the event-level HED string should include this tag.]</nowiki>
+* relatedTag <nowiki>{nodeProperty, isInheritedProperty} [A schema attribute suggesting HED tags that are closely related to this tag. This attribute is used by tagging tools.]</nowiki>
+* requireChild <nowiki>{boolProperty, nodeProperty} [A schema attribute indicating that one of the node elements descendants must be included when using this tag.]</nowiki>
+* required <nowiki>{boolProperty, nodeProperty} [A schema attribute indicating that every event-level HED string should include this tag.]</nowiki>
+* reserved <nowiki>{boolProperty, nodeProperty} [A schema attribute indicating that this tag has special meaning and requires special handling by tools.]</nowiki>
+* rooted <nowiki>{nodeProperty} [Indicates a top-level library schema node is identical to a node of the same name in the partnered standard schema. This attribute can only appear in nodes that have the inLibrary schema attribute.]</nowiki>
+* SIUnit <nowiki>{boolProperty, unitProperty} [A schema attribute indicating that this unit element is an SI unit and can be modified by multiple and submultiple names. Note that some units such as byte are designated as SI units although they are not part of the standard.]</nowiki>
+* SIUnitModifier <nowiki>{boolProperty, unitModifierProperty} [A schema attribute indicating that this SI unit modifier represents a multiple or submultiple of a base unit rather than a unit symbol.]</nowiki>
+* SIUnitSymbolModifier <nowiki>{boolProperty, unitModifierProperty} [A schema attribute indicating that this SI unit modifier represents a multiple or submultiple of a unit symbol rather than a base symbol.]</nowiki>

+* tagGroup <nowiki>{boolProperty, nodeProperty} [A schema attribute indicating the tag can only appear inside a tag group.]</nowiki>
+* takesValue <nowiki>{boolProperty, nodeProperty} [A schema attribute indicating the tag is a hashtag placeholder that is expected to be replaced with a user-defined value.]</nowiki>
+* topLevelTagGroup <nowiki>{boolProperty, nodeProperty} [A schema attribute indicating that this tag (or its descendants) can only appear in a top-level tag group. A tag group can have at most one tag with this attribute.]</nowiki>
+* unique <nowiki>{boolProperty, nodeProperty} [A schema attribute indicating that only one of this tag or its descendants can be used  in the event-level HED string.]</nowiki>
+* unitClass <nowiki>{nodeProperty} [A schema attribute specifying which unit class this value tag belongs to.]</nowiki>
+* unitPrefix <nowiki>{boolProperty, unitProperty} [A schema attribute applied specifically to unit elements to designate that the unit indicator is a prefix (e.g., dollar sign in the currency units).]</nowiki>
+* unitSymbol <nowiki>{boolProperty, unitProperty} [A schema attribute indicating this tag is an abbreviation or symbol representing a type of unit. Unit symbols represent both the singular and the plural and thus cannot be pluralized.]</nowiki>
+* valueClass <nowiki>{nodeProperty} [A schema attribute specifying which value class this value tag belongs to.]</nowiki>
+
+'''Properties'''
+* boolProperty <nowiki>[Indicates that the schema attribute represents something that is either true or false and does not have a value. Attributes without this value are assumed to have string values.]</nowiki>
+* elementProperty <nowiki>[Indicates this schema attribute can apply to any type of element(tag term, unit class, etc).]</nowiki>
+* isInheritedProperty <nowiki>[Indicates that this attribute is inherited by child nodes. This property only applies to schema attributes for nodes.]</nowiki>
+* nodeProperty <nowiki>[Indicates this schema attribute applies to node (tag-term) elements. This was added to allow for an attribute to apply to multiple elements.]</nowiki>
+* unitClassProperty <nowiki>[Indicates that the schema attribute is meant to be applied to unit classes.]</nowiki>
+* unitModifierProperty <nowiki>[Indicates that the schema attribute is meant to be applied to unit modifier classes.]</nowiki>
+* unitProperty <nowiki>[Indicates that the schema attribute is meant to be applied to units within a unit class.]</nowiki>
+* valueClassProperty <nowiki>[Indicates that the schema attribute is meant to be applied to value classes.]</nowiki>
+'''Epilogue'''
+The Standardized Computer-based Organized Reporting of EEG (SCORE) is a standard terminology for scalp EEG data assessment designed for use in clinical practice that may also be used for research purposes.
+The SCORE standard defines terms for describing phenomena observed in scalp EEG data. It is also potentially applicable (with some suitable extensions) to EEG recorded in critical care and neonatal settings.
+The SCORE standard received European consensus and has been endorsed by the European Chapter of the International Federation of Clinical Neurophysiology (IFCN) and the International League Against Epilepsy (ILAE) Commission on European Affairs.
+A second revised and extended version of SCORE achieved international consensus.

-   <prologue>This schema is a Hierarchical Event Descriptors (HED) Library Schema implementation of Standardized Computer-based Organized Reporting of EEG (SCORE)[1,2] for describing events occurring during neuroimaging time series recordings.
-The HED-SCORE library schema allows neurologists, neurophysiologists, and brain researchers to annotate electrophysiology recordings using terms from an internationally accepted set of defined terms (SCORE) compatible with the HED framework.
-The resulting annotations are understandable to clinicians and directly usable in computer analysis.
-
-Future extensions may be implemented in the HED-SCORE library schema.

-            <name>Posterior-dominant-rhythm</name>
-            <description>Rhythmic activity occurring during wakefulness over the posterior regions of the head, generally with maximum amplitudes over the occipital areas. Amplitude varies. Best seen with eyes closed and during physical relaxation and relative mental inactivity. Blocked or attenuated by attention, especially visual, and mental effort. In adults this is the alpha rhythm, and the frequency is 8 to 13 Hz. However the frequency can be higher or lower than this range (often a supra or sub harmonic of alpha frequency) and is called alpha variant rhythm (fast and slow alpha variant rhythm). In children, the normal range of the frequency of the posterior dominant rhythm is age-dependant.</description>

-            <description>EEG rhythm at 7-11 Hz composed of arch-shaped waves occurring over the central or centro-parietal regions of the scalp during wakefulness. Amplitudes varies but is mostly below 50 microV. Blocked or attenuated most clearly by contralateral movement, thought of movement, readiness to move or tactile stimulation.</description>

If the eye blink is unilateral, consider prosthetic eye. If it is in F8 rather than Fp2 then the electrodes are plugged in wrong.</description>

-               <description>Example for EEG: There is an upward deflection in the Fp2-F8 derivation, when the eyes move to the right side. In this case F8 becomes more positive and therefore. When the eyes move to the left, F7 becomes more positive and there is an upward deflection in the Fp1-F7 derivation.</description>

The downward rotation of the eyeball was associated with the negative deflection. The time course of the deflections was similar to the time course of the eyeball movement.</description>

-               <description>The tongue functions as a dipole, with the tip negative with respect to the base. The artifact produced by the tongue has a broad potential field that drops from frontal to occipital areas, although it is less steep than that produced by eye movement artifacts. The amplitude of the potentials is greater inferiorly than in parasagittal regions; the frequency is variable but usually in the delta range. Chewing and sucking can produce similar artifacts.</description>

-               <description>Example for EEG: Large amplitude artifact, with irregular morphology (usually resembling a slow-wave or a wave with complex morphology) seen in one or several channels, due to movement. If the causing movement is repetitive, the artifact might resemble a rhythmic EEG activity.</description>

-               <description>Respiration can produce 2 kinds of artifacts. One type is in the form of slow and rhythmic activity, synchronous with the body movements of respiration and mechanically affecting the impedance of (usually) one electrode. The other type can be slow or sharp waves that occur synchronously with inhalation or exhalation and involve those electrodes on which the patient is lying.</description>

-               <description>Example for EEG: Far-field potential generated in the heart. The voltage and apparent surface of the artifact vary from derivation to derivation and, consequently, from montage to montage. The artifact is observed best in referential montages using earlobe electrodes A1 and A2. ECG artifact is recognized easily by its rhythmicity/regularity and coincidence with the ECG tracing.</description>

-               <description>Myogenic potentials are the most common artifacts. Frontalis and temporalis muscles (ex..: clenching of jaw muscles) are common causes. Generally, the potentials generated in the muscles are of shorter duration than those generated in the brain. The frequency components are usually beyond 30-50 Hz, and the bursts are arrhythmic.</description>

-            <description>Seizure type frequent in neonates, sometimes referred to as motor automatisms; they may include random and roving eye movements, sucking, chewing motions, tongue protrusion, rowing or swimming or boxing movements of the arms, pedaling and bicycling movements of the lower limbs; apneic seizures are relatively common. Although some subtle seizures are associated with rhythmic ictal EEG discharges, and are clearly epileptic, ictal EEG often does not show typical epileptic activity.</description>

-               <description>PLMS. Periodic limb movement in sleep. Episodes are characterized by brief (0.5- to 5.0-second) lower-extremity movements during sleep, which typically occur at 20- to 40-second intervals, most commonly during the first 3 hours of sleep. The affected individual is usually not aware of the movements or of the transient partial arousals.</description>

-               <name>Sleep-walking</name>
-               <description>Episodes characterized by ambulation during sleep; the patient is difficult to arouse during an episode, and is usually amnesic following the episode. Episodes usually occur in the first third of the night during slow wave sleep. Polysomnographic recordings demonstrate 2 abnormalities during the first sleep cycle: frequent, brief, non-behavioral EEG-defined arousals prior to the somnambulistic episode and abnormally low gamma (0.75-2.0 Hz) EEG power on spectral analysis, correlating with high-voltage (hyper-synchronic gamma) waves lasting 10 to 15 s occurring just prior to the movement. This is followed by stage I NREM sleep, and there is no evidence of complete awakening.</description>

Cataplexy usually is precipitated by an outburst of emotional expression-notably laughter, anger, or startle. It is one of the tetrad of symptoms of narcolepsy. During cataplexy, respiration and voluntary eye movements are not compromised. Consciousness is preserved.</description>

-                  <description>EEG rhythm between 14 and 40 Hz, which is considered part of the background (ongoing) activity but does not fulfill the criteria of the posterior dominant rhythm. Most characteristically: a rhythm from 14 to 40 Hz recorded over the fronto-central regions of the head during wakefulness. Amplitude of the beta rhythm varies but is mostly below 30 microV. Other beta rhythms are most prominent in other locations or are diffuse.</description>

-            <description>Location can be scored for findings. Semiologic finding can also be characterized by the somatotopic modifier (i.e. the part of the body where it occurs). In this respect, laterality (left, right, symmetric, asymmetric, left greater than right, right greater than left), body part (eyelid, face, arm, leg, trunk, visceral, hemi-) and centricity (axial, proximal limb, distal limb) can be scored.</description>

-                     <description>A sudden onset, interruption of ongoing activities, a blank stare, possibly a brief upward deviation of the eyes. Usually the patient will be unresponsive when spoken to. Duration is a few seconds to half a minute with very rapid recovery. Although not always available, an EEG would show generalized epileptiform discharges during the event. An absence seizure is by definition a seizure of generalized onset. The word is not synonymous with a blank stare, which also can be encountered with focal onset seizures. Definition from ILAE 2017 Classification of Seizure Types Expanded Version</description>

Eyelid myoclonia can be associated with absences, but also can be motor seizures without a corresponding absence, making them difficult to categorize. The 2017 classification groups them with nonmotor (absence) seizures, which may seem counterintuitive, but the myoclonia in this instance is meant to link with absence, rather than with nonmotor.

-               <description>Seizure semiology refers to the clinical features or signs that are observed during a seizure, such as the type of movements or behaviors exhibited by the person having the seizure, the duration of the seizure, the level of consciousness, and any associated symptoms such as aura or postictal confusion. In other words, seizure semiology describes the physical manifestations of a seizure. Semiology is described according to the ILAE Glossary of Descriptive Terminology for Ictal Semiology (Blume et al., 2001). Besides the name, the semiologic finding can also be characterized by the somatotopic modifier, laterality, body part and centricity. Uses Location-property tags.</description>

-                     <description>The term describes events in which (1) disturbance of cognition is the predominant or most apparent feature, and (2a) two or more of the following components are involved, or (2b) involvement of such components remains undetermined. Otherwise, use the more specific term (e.g., mnemonic experiential seizure  or hallucinatory experiential seizure). Components of cognition: ++ perception: symbolic conception of sensory information ++ attention: appropriate selection of a principal perception or task ++ emotion: appropriate affective significance of a perception ++ memory: ability to store and retrieve percepts or concepts ++ executive function: anticipation, selection, monitoring of consequences, and initiation of motor activity including praxis, speech.</description>

-                  <description>Prodrome is a preictal phenomenon, and it is defined as a subjective or objective clinical alteration (e.g., ill-localized sensation or agitation) that heralds the onset of an epileptic seizure but does not form part of it (Blume et al., 2001). Therefore, prodrome should be distinguished from aura (which is an ictal phenomenon).</description>

-               <description>For posterior dominant rhythm: a difference in amplitude between the homologous area on opposite sides of the head that consistently exceeds 50 percent. When symmetrical could be labeled with base schema Symmetrical tag. For sleep: Absence or consistently marked amplitude asymmetry (greater than 50 percent) of a normal sleep graphoelement.</description>

-            <description>Characteristic rhythms mostly at 4-5 Hz, recorded most prominently over the posterior regions of the head. Generally alternate, or are intermixed, with alpha rhythm to which they often are harmonically related. Amplitude varies but is frequently close to 50 micro V. Blocked or attenuated by attention, especially visual, and mental effort. Comment: slow alpha variant rhythms should be distinguished from posterior slow waves characteristic of children and adolescents and occasionally seen in young adults.</description>

-            <description>Physiologic response consisting of rhythmic activity elicited over the posterior regions of the head by repetitive photic stimulation at frequencies of about 5-30 Hz. Comments: term should be limited to activity time-locked to the stimulus and of frequency identical or harmonically related to the stimulus frequency. Photic driving should be distinguished from the visual evoked potentials elicited by isolated flashes of light or flashes repeated at very low frequency.</description>

-            <description>A response to intermittent photic stimulation characterized by the appearance in the record of brief, repetitive muscular artifacts (spikes) over the anterior regions of the head. These often increase gradually in amplitude as stimuli are continued and cease promptly when the stimulus is withdrawn. Comment: this response is frequently associated with flutter of the eyelids and vertical oscillations of the eyeballs and sometimes with discrete jerking mostly involving the musculature of the face and head. (Preferred to synonym: photo-myoclonic response).</description>

Duration greater than 0.5 s. Amplitude is generally maximal in the frontal vertex. K complexes occur during nonREM sleep, apparently spontaneously, or in response to sudden sensory / auditory stimuli, and are not specific for any individual sensory modality.</description>

-            <description>Benign epileptiform Transients of Sleep (BETS). Small sharp spikes (SSS) of very short duration and low amplitude, often followed by a small theta wave, occurring in the temporal regions during drowsiness and light sleep. They occur on one or both sides (often asynchronously). The main negative and positive components are of about equally spiky character. Rarely seen in children, they are seen most often in adults and the elderly. Two thirds of the patients have a history of epileptic seizures.</description>

-            <description>Subclinical rhythmic EEG discharge of adults (SERDA). A rhythmic pattern seen in the adult age group, mainly in the waking state or drowsiness. It consists of a mixture of frequencies, often predominant in the theta range. The onset may be fairly abrupt with widespread sharp rhythmical theta and occasionally with delta activity. As to the spatial distribution, a maximum of this discharge is usually found over the centroparietal region and especially over the vertex. It may resemble a seizure discharge but is not accompanied by any clinical signs or symptoms.</description>

-   <epilogue>The Standardized Computer-based Organized Reporting of EEG (SCORE) is a standard terminology for scalp EEG data assessment designed for use in clinical practice that may also be used for research purposes.
-The SCORE standard defines terms for describing phenomena observed in scalp EEG data. It is also potentially applicable (with some suitable extensions) to EEG recorded in critical care and neonatal settings.
-The SCORE standard received European consensus and has been endorsed by the European Chapter of the International Federation of Clinical Neurophysiology (IFCN) and the International League Against Epilepsy (ILAE) Commission on European Affairs.
-A second revised and extended version of SCORE achieved international consensus.

+   <prologue>This schema is a Hierarchical Event Descriptors (HED) Library Schema implementation of Standardized Computer-based Organized Reporting of EEG (SCORE)[1,2] for describing events occurring during neuroimaging time series recordings.
+The HED-SCORE library schema allows neurologists, neurophysiologists, and brain researchers to annotate electrophysiology recordings using terms from an internationally accepted set of defined terms (SCORE) compatible with the HED framework.
+The resulting annotations are understandable to clinicians and directly usable in computer analysis.
+
+Future extensions may be implemented in the HED-SCORE library schema.

+            <description>Rhythmic activity occurring during wakefulness over the posterior regions of the head, generally with maximum amplitudes over the occipital areas. Amplitude varies. Best seen with eyes closed and during physical relaxation and relative mental inactivity. Blocked or attenuated by attention, especially visual, and mental effort. In adults this is the alpha rhythm, and the frequency is 8 to 13 Hz. However the frequency can be higher or lower than this range (often a supra or sub harmonic of alpha frequency) and is called alpha variant rhythm (fast and slow alpha variant rhythm). In children, the normal range of the frequency of the posterior dominant rhythm is age-dependant.</description>

+            <description>EEG rhythm at 7-11 Hz composed of arch-shaped waves occurring over the central or centro-parietal regions of the scalp during wakefulness. Amplitudes varies but is mostly below 50 microV. Blocked or attenuated most clearly by contralateral movement, thought of movement, readiness to move or tactile stimulation.</description>

+            <description>Seizure type frequent in neonates, sometimes referred to as motor automatisms; they may include random and roving eye movements, sucking, chewing motions, tongue protrusion, rowing or swimming or boxing movements of the arms, pedaling and bicycling movements of the lower limbs; apneic seizures are relatively common. Although some subtle seizures are associated with rhythmic ictal EEG discharges, and are clearly epileptic, ictal EEG often does not show typical epileptic activity.</description>

Episodes are characterized by brief (0.5- to 5.0-second) lower-extremity movements during sleep, which typically occur at 20- to 40-second intervals, most commonly during the first 3 hours of sleep. The affected individual is usually not aware of the movements or of the transient partial arousals.</description>

+               <description>Episodes characterized by ambulation during sleep; the patient is difficult to arouse during an episode, and is usually amnesic following the episode. Episodes usually occur in the first third of the night during slow wave sleep. Polysomnographic recordings demonstrate 2 abnormalities during the first sleep cycle: frequent, brief, non-behavioral EEG-defined arousals prior to the somnambulistic episode and abnormally low gamma (0.75-2.0 Hz) EEG power on spectral analysis, correlating with high-voltage (hyper-synchronic gamma) waves lasting 10 to 15 s occurring just prior to the movement. This is followed by stage I NREM sleep, and there is no evidence of complete awakening.</description>

+            <description>Episode with loss of consciousness and muscle tone that is abrupt in onset, of short duration and followed by rapid recovery; it occurs in response to transient impairment of cerebral perfusion. Typical prodromal symptoms often herald onset of syncope and postictal symptoms are minimal. Syncopal convulsions resulting from cerebral anoxia are common but are not a form of epilepsy, nor are there any accompanying EEG ictal discharges.</description>

+            <name>Cataplexy</name>
+            <description>A sudden decrement in muscle tone and loss of deep tendon reflexes, leading to muscle weakness, paralysis, or postural collapse. Cataplexy usually is precipitated by an outburst of emotional expression-notably laughter, anger, or startle. It is one of the tetrad of symptoms of narcolepsy. During cataplexy, respiration and voluntary eye movements are not compromised. Consciousness is preserved.</description>

Generally alternate, or are intermixed, with alpha rhythm to which they often are harmonically related. Amplitude varies but is frequently close to 50 micro V. Blocked or attenuated by attention, especially visual, and mental effort. Comment: slow alpha variant rhythms should be distinguished from posterior slow waves characteristic of children and adolescents and occasionally seen in young adults.</description>

These often increase gradually in amplitude as stimuli are continued and cease promptly when the stimulus is withdrawn. Comment: this response is frequently associated with flutter of the eyelids and vertical oscillations of the eyeballs and sometimes with discrete jerking mostly involving the musculature of the face and head.

Small sharp spikes (SSS) of very short duration and low amplitude, often followed by a small theta wave, occurring in the temporal regions during drowsiness and light sleep. They occur on one or both sides (often asynchronously). The main negative and positive components are of about equally spiky character. Rarely seen in children, they are seen most often in adults and the elderly. Two thirds of the patients have a history of epileptic seizures.</description>

+            <description>Synonym: Pseudo petit mal discharge. Paroxysmal discharge that consists of generalized or nearly generalized high voltage 3 to 4/sec waves with poorly developed spike in the positive trough between the slow waves, occurring in drowsiness only. It is found only in infancy and early childhood when marked hypnagogic rhythmical theta activity is paramount in the drowsy state.</description>

+            <description>Subclinical rhythmic EEG discharge of adults (SERDA). A rhythmic pattern seen in the adult age group, mainly in the waking state or drowsiness. It consists of a mixture of frequencies, often predominant in the theta range. The onset may be fairly abrupt with widespread sharp rhythmical theta and occasionally with delta activity. As to the spatial distribution, a maximum of this discharge is usually found over the centroparietal region and especially over the vertex. It may resemble a seizure discharge but is not accompanied by any clinical signs or symptoms.</description>

+               <description>The tongue functions as a dipole, with the tip negative with respect to the base. The artifact produced by the tongue has a broad potential field that drops from frontal to occipital areas, although it is less steep than that produced by eye movement artifacts. The amplitude of the potentials is greater inferiorly than in parasagittal regions; the frequency is variable but usually in the delta range. Chewing and sucking can produce similar artifacts.</description>

One type is in the form of slow and rhythmic activity, synchronous with the body movements of respiration and mechanically affecting the impedance of (usually) one electrode. The other type can be slow or sharp waves that occur synchronously with inhalation or exhalation and involve those electrodes on which the patient is lying.</description>

+               <description>Example for EEG: Occurs when an EEG electrode is placed over a pulsating vessel. The pulsation can cause slow waves that may simulate EEG activity. A direct relationship exists between ECG and the pulse waves (200-300 millisecond delay after ECG equals QRS complex).</description>

+               <description>Example for EEG: Far-field potential generated in the heart. The voltage and apparent surface of the artifact vary from derivation to derivation and, consequently, from montage to montage. The artifact is observed best in referential montages using earlobe electrodes A1 and A2. ECG artifact is recognized easily by its rhythmicity/regularity and coincidence with the ECG tracing.</description>

+               <description>Myogenic potentials are the most common artifacts. Frontalis and temporalis muscles (ex..: clenching of jaw muscles) are common causes. Generally, the potentials generated in the muscles are of shorter duration than those generated in the brain. The frequency components are usually beyond 30-50 Hz, and the bursts are arrhythmic.</description>

+                  <description>EEG rhythm between 14 and 40 Hz, which is considered part of the background (ongoing) activity but does not fulfill the criteria of the posterior dominant rhythm. Most characteristically: a rhythm from 14 to 40 Hz recorded over the fronto-central regions of the head during wakefulness. Amplitude of the beta rhythm varies but is mostly below 30 microV. Other beta rhythms are most prominent in other locations or are diffuse.</description>

+            <description>Location can be scored for findings. Semiologic finding can also be characterized by the somatotopic modifier (i.e. the part of the body where it occurs). In this respect, laterality (left, right, symmetric, asymmetric, left greater than right, right greater than left), body part (eyelid, face, arm, leg, trunk, visceral, hemi-) and centricity (axial, proximal limb, distal limb) can be scored.</description>

Usually the patient will be unresponsive when spoken to. Duration is a few seconds to half a minute with very rapid recovery. Although not always available, an EEG would show generalized epileptiform discharges during the event. An absence seizure is by definition a seizure of generalized onset. The word is not synonymous with a blank stare, which also can be encountered with focal onset seizures. Definition from ILAE 2017 Classification of Seizure Types Expanded Version</description>

+                     <description>A myoclonic absence seizure refers to an absence seizure with rhythmic three-per-second myoclonic movements, causing ratcheting abduction of the upper limbs leading to progressive arm elevation, and associated with three-per-second generalized spike-wave discharges. Duration is typically 10 to 60 s. Impairment of consciousness may not be obvious. Definition from ILAE 2017 Classification of Seizure Types Expanded Version</description>

+                     <description>Eyelid myoclonia are myoclonic jerks of the eyelids and upward deviation of the eyes, often precipitated by closing the eyes or by light. Eyelid myoclonia can be associated with absences, but also can be motor seizures without a corresponding absence, making them difficult to categorize. The 2017 classification groups them with nonmotor (absence) seizures, which may seem counterintuitive, but the myoclonia in this instance is meant to link with absence, rather than with nonmotor.

+               <description>Seizure semiology refers to the clinical features or signs that are observed during a seizure, such as the type of movements or behaviors exhibited by the person having the seizure, the duration of the seizure, the level of consciousness, and any associated symptoms such as aura or postictal confusion. In other words, seizure semiology describes the physical manifestations of a seizure. Semiology is described according to the ILAE Glossary of Descriptive Terminology for Ictal Semiology (Blume et al., 2001). Besides the name, the semiologic finding can also be characterized by the somatotopic modifier, laterality, body part and centricity. Uses Location-property tags.</description>

Otherwise, use the more specific term (e.g., mnemonic experiential seizure  or hallucinatory experiential seizure). Components of cognition: ++ perception: symbolic conception of sensory information ++ attention: appropriate selection of a principal perception or task ++ emotion: appropriate affective significance of a perception ++ memory: ability to store and retrieve percepts or concepts ++ executive function: anticipation, selection, monitoring of consequences, and initiation of motor activity including praxis, speech.</description>

+                  <description>Prodrome is a preictal phenomenon, and it is defined as a subjective or objective clinical alteration (e.g., ill-localized sensation or agitation) that heralds the onset of an epileptic seizure but does not form part of it (Blume et al., 2001). Therefore, prodrome should be distinguished from aura (which is an ictal phenomenon).</description>

+   <epilogue>The Standardized Computer-based Organized Reporting of EEG (SCORE) is a standard terminology for scalp EEG data assessment designed for use in clinical practice that may also be used for research purposes.
+The SCORE standard defines terms for describing phenomena observed in scalp EEG data. It is also potentially applicable (with some suitable extensions) to EEG recorded in critical care and neonatal settings.
+The SCORE standard received European consensus and has been endorsed by the European Chapter of the International Federation of Clinical Neurophysiology (IFCN) and the International League Against Epilepsy (ILAE) Commission on European Affairs.
+A second revised and extended version of SCORE achieved international consensus.

+'''Prologue'''
+This schema is a Hierarchical Event Descriptors (HED) Library Schema implementation of Standardized Computer-based Organized Reporting of EEG (SCORE)[1,2] for describing events occurring during neuroimaging time series recordings.
+The HED-SCORE library schema allows neurologists, neurophysiologists, and brain researchers to annotate electrophysiology recordings using terms from an internationally accepted set of defined terms (SCORE) compatible with the HED framework.
+The resulting annotations are understandable to clinicians and directly usable in computer analysis.
+
+Future extensions may be implemented in the HED-SCORE library schema.
+For more information see https://hed-schema-library.readthedocs.io/en/latest/index.html.

Amplitude varies. Best seen with eyes closed and during physical relaxation and relative mental inactivity. Blocked or attenuated by attention, especially visual, and mental effort. In adults this is the alpha rhythm, and the frequency is 8 to 13 Hz.

In children, the normal range of the frequency of the posterior dominant rhythm is age-dependant.]</nowiki>

+*** Absence-seizure <nowiki>[Absence seizures present with a sudden cessation of activity and awareness. Absence seizures tend to occur in younger age groups, have more sudden start and termination, and they usually display less complex automatisms than do focal seizures with impaired awareness, but the distinctions are not absolute.

Although not always available, an EEG would show generalized epileptiform discharges during the event. An absence seizure is by definition a seizure of generalized onset. The word is not synonymous with a blank stare, which also can be encountered with focal onset seizures. Definition from ILAE 2017 Classification of Seizure Types Expanded Version]</nowiki>

Eyelid myoclonia can be associated with absences, but also can be motor seizures without a corresponding absence, making them difficult to categorize. The 2017 classification groups them with nonmotor (absence) seizures, which may seem counterintuitive, but the myoclonia in this instance is meant to link with absence, rather than with nonmotor.

+** Seizure-semiology-manifestation <nowiki>{requireChild} [Seizure semiology refers to the clinical features or signs that are observed during a seizure, such as the type of movements or behaviors exhibited by the person having the seizure, the duration of the seizure, the level of consciousness, and any associated symptoms such as aura or postictal confusion. In other words, seizure semiology describes the physical manifestations of a seizure. Semiology is described according to the ILAE Glossary of Descriptive Terminology for Ictal Semiology (Blume et al., 2001). Besides the name, the semiologic finding can also be characterized by the somatotopic modifier, laterality, body part and centricity. Uses Location-property tags.]</nowiki>

+The Standardized Computer-based Organized Reporting of EEG (SCORE) is a standard terminology for scalp EEG data assessment designed for use in clinical practice that may also be used for research purposes.
+The SCORE standard defines terms for describing phenomena observed in scalp EEG data. It is also potentially applicable (with some suitable extensions) to EEG recorded in critical care and neonatal settings.
+The SCORE standard received European consensus and has been endorsed by the European Chapter of the International Federation of Clinical Neurophysiology (IFCN) and the International League Against Epilepsy (ILAE) Commission on European Affairs.
+A second revised and extended version of SCORE achieved international consensus.

-   <prologue>This schema is a Hierarchical Event Descriptors (HED) Library Schema implementation of Standardized Computer-based Organized Reporting of EEG (SCORE)[1,2] for describing events occurring during neuroimaging time series recordings.
-The HED-SCORE library schema allows neurologists, neurophysiologists, and brain researchers to annotate electrophysiology recordings using terms from an internationally accepted set of defined terms (SCORE) compatible with the HED framework.
-The resulting annotations are understandable to clinicians and directly usable in computer analysis.
-
-Future extensions may be implemented in the HED-SCORE library schema.

-            <description>Rhythmic activity occurring during wakefulness over the posterior regions of the head, generally with maximum amplitudes over the occipital areas. Amplitude varies. Best seen with eyes closed and during physical relaxation and relative mental inactivity. Blocked or attenuated by attention, especially visual, and mental effort. In adults this is the alpha rhythm, and the frequency is 8 to 13 Hz. However the frequency can be higher or lower than this range (often a supra or sub harmonic of alpha frequency) and is called alpha variant rhythm (fast and slow alpha variant rhythm). In children, the normal range of the frequency of the posterior dominant rhythm is age-dependant.</description>

-            <description>EEG rhythm at 7-11 Hz composed of arch-shaped waves occurring over the central or centro-parietal regions of the scalp during wakefulness. Amplitudes varies but is mostly below 50 microV. Blocked or attenuated most clearly by contralateral movement, thought of movement, readiness to move or tactile stimulation.</description>

-               <description>The tongue functions as a dipole, with the tip negative with respect to the base. The artifact produced by the tongue has a broad potential field that drops from frontal to occipital areas, although it is less steep than that produced by eye movement artifacts. The amplitude of the potentials is greater inferiorly than in parasagittal regions; the frequency is variable but usually in the delta range. Chewing and sucking can produce similar artifacts.</description>

One type is in the form of slow and rhythmic activity, synchronous with the body movements of respiration and mechanically affecting the impedance of (usually) one electrode. The other type can be slow or sharp waves that occur synchronously with inhalation or exhalation and involve those electrodes on which the patient is lying.</description>

The voltage and apparent surface of the artifact vary from derivation to derivation and, consequently, from montage to montage. The artifact is observed best in referential montages using earlobe electrodes A1 and A2. ECG artifact is recognized easily by its rhythmicity/regularity and coincidence with the ECG tracing.</description>

-               <description>Myogenic potentials are the most common artifacts. Frontalis and temporalis muscles (ex..: clenching of jaw muscles) are common causes. Generally, the potentials generated in the muscles are of shorter duration than those generated in the brain. The frequency components are usually beyond 30-50 Hz, and the bursts are arrhythmic.</description>

-            <description>Seizure type frequent in neonates, sometimes referred to as motor automatisms; they may include random and roving eye movements, sucking, chewing motions, tongue protrusion, rowing or swimming or boxing movements of the arms, pedaling and bicycling movements of the lower limbs; apneic seizures are relatively common. Although some subtle seizures are associated with rhythmic ictal EEG discharges, and are clearly epileptic, ictal EEG often does not show typical epileptic activity.</description>

-               <description>PLMS. Periodic limb movement in sleep. Episodes are characterized by brief (0.5- to 5.0-second) lower-extremity movements during sleep, which typically occur at 20- to 40-second intervals, most commonly during the first 3 hours of sleep. The affected individual is usually not aware of the movements or of the transient partial arousals.</description>

-               <description>Episodes characterized by ambulation during sleep; the patient is difficult to arouse during an episode, and is usually amnesic following the episode. Episodes usually occur in the first third of the night during slow wave sleep. Polysomnographic recordings demonstrate 2 abnormalities during the first sleep cycle: frequent, brief, non-behavioral EEG-defined arousals prior to the somnambulistic episode and abnormally low gamma (0.75-2.0 Hz) EEG power on spectral analysis, correlating with high-voltage (hyper-synchronic gamma) waves lasting 10 to 15 s occurring just prior to the movement. This is followed by stage I NREM sleep, and there is no evidence of complete awakening.</description>

Typical prodromal symptoms often herald onset of syncope and postictal symptoms are minimal. Syncopal convulsions resulting from cerebral anoxia are common but are not a form of epilepsy, nor are there any accompanying EEG ictal discharges.</description>

Cataplexy usually is precipitated by an outburst of emotional expression-notably laughter, anger, or startle. It is one of the tetrad of symptoms of narcolepsy. During cataplexy, respiration and voluntary eye movements are not compromised. Consciousness is preserved.</description>

-                  <description>EEG rhythm between 14 and 40 Hz, which is considered part of the background (ongoing) activity but does not fulfill the criteria of the posterior dominant rhythm. Most characteristically: a rhythm from 14 to 40 Hz recorded over the fronto-central regions of the head during wakefulness. Amplitude of the beta rhythm varies but is mostly below 30 microV. Other beta rhythms are most prominent in other locations or are diffuse.</description>

-            <description>Location can be scored for findings. Semiologic finding can also be characterized by the somatotopic modifier (i.e. the part of the body where it occurs). In this respect, laterality (left, right, symmetric, asymmetric, left greater than right, right greater than left), body part (eyelid, face, arm, leg, trunk, visceral, hemi-) and centricity (axial, proximal limb, distal limb) can be scored.</description>

-                  <description>Absence seizures present with a sudden cessation of activity and awareness. Absence seizures tend to occur in younger age groups, have more sudden start and termination, and they usually display less complex automatisms than do focal seizures with impaired awareness, but the distinctions are not absolute. EEG information may be required for accurate classification. Definition from ILAE 2017 Classification of Seizure Types Expanded Version</description>

-                     <name>Typical-absence-seizure</name>
-                     <description>A sudden onset, interruption of ongoing activities, a blank stare, possibly a brief upward deviation of the eyes. Usually the patient will be unresponsive when spoken to. Duration is a few seconds to half a minute with very rapid recovery. Although not always available, an EEG would show generalized epileptiform discharges during the event. An absence seizure is by definition a seizure of generalized onset. The word is not synonymous with a blank stare, which also can be encountered with focal onset seizures. Definition from ILAE 2017 Classification of Seizure Types Expanded Version</description>

Duration is typically 10 to 60 s. Impairment of consciousness may not be obvious. Definition from ILAE 2017 Classification of Seizure Types Expanded Version</description>

-                     <description>Eyelid myoclonia are myoclonic jerks of the eyelids and upward deviation of the eyes, often precipitated by closing the eyes or by light. Eyelid myoclonia can be associated with absences, but also can be motor seizures without a corresponding absence, making them difficult to categorize. The 2017 classification groups them with nonmotor (absence) seizures, which may seem counterintuitive, but the myoclonia in this instance is meant to link with absence, rather than with nonmotor.

-               <description>Seizure semiology refers to the clinical features or signs that are observed during a seizure, such as the type of movements or behaviors exhibited by the person having the seizure, the duration of the seizure, the level of consciousness, and any associated symptoms such as aura or postictal confusion. In other words, seizure semiology describes the physical manifestations of a seizure. Semiology is described according to the ILAE Glossary of Descriptive Terminology for Ictal Semiology (Blume et al., 2001). Besides the name, the semiologic finding can also be characterized by the somatotopic modifier, laterality, body part and centricity. Uses Location-property tags.</description>

Otherwise, use the more specific term (e.g., mnemonic experiential seizure  or hallucinatory experiential seizure). Components of cognition: ++ perception: symbolic conception of sensory information ++ attention: appropriate selection of a principal perception or task ++ emotion: appropriate affective significance of a perception ++ memory: ability to store and retrieve percepts or concepts ++ executive function: anticipation, selection, monitoring of consequences, and initiation of motor activity including praxis, speech.</description>

-                  <description>Prodrome is a preictal phenomenon, and it is defined as a subjective or objective clinical alteration (e.g., ill-localized sensation or agitation) that heralds the onset of an epileptic seizure but does not form part of it (Blume et al., 2001). Therefore, prodrome should be distinguished from aura (which is an ictal phenomenon).</description>

-            <description>Characteristic rhythms mostly at 4-5 Hz, recorded most prominently over the posterior regions of the head. Generally alternate, or are intermixed, with alpha rhythm to which they often are harmonically related. Amplitude varies but is frequently close to 50 micro V. Blocked or attenuated by attention, especially visual, and mental effort. Comment: slow alpha variant rhythms should be distinguished from posterior slow waves characteristic of children and adolescents and occasionally seen in young adults.</description>

Comments: term should be limited to activity time-locked to the stimulus and of frequency identical or harmonically related to the stimulus frequency. Photic driving should be distinguished from the visual evoked potentials elicited by isolated flashes of light or flashes repeated at very low frequency.</description>

-            <description>A response to intermittent photic stimulation characterized by the appearance in the record of brief, repetitive muscular artifacts (spikes) over the anterior regions of the head. These often increase gradually in amplitude as stimuli are continued and cease promptly when the stimulus is withdrawn. Comment: this response is frequently associated with flutter of the eyelids and vertical oscillations of the eyeballs and sometimes with discrete jerking mostly involving the musculature of the face and head. (Preferred to synonym: photo-myoclonic response).</description>

It consists of a mixture of frequencies, often predominant in the theta range. The onset may be fairly abrupt with widespread sharp rhythmical theta and occasionally with delta activity. As to the spatial distribution, a maximum of this discharge is usually found over the centroparietal region and especially over the vertex. It may resemble a seizure discharge but is not accompanied by any clinical signs or symptoms.</description>

-   <epilogue>The Standardized Computer-based Organized Reporting of EEG (SCORE) is a standard terminology for scalp EEG data assessment designed for use in clinical practice that may also be used for research purposes.
-The SCORE standard defines terms for describing phenomena observed in scalp EEG data. It is also potentially applicable (with some suitable extensions) to EEG recorded in critical care and neonatal settings.
-The SCORE standard received European consensus and has been endorsed by the European Chapter of the International Federation of Clinical Neurophysiology (IFCN) and the International League Against Epilepsy (ILAE) Commission on European Affairs.
-A second revised and extended version of SCORE achieved international consensus.

+            <description>Rhythmic activity occurring during wakefulness over the posterior regions of the head, generally with maximum amplitudes over the occipital areas. Amplitude varies. Best seen with eyes closed and during physical relaxation and relative mental inactivity. Blocked or attenuated by attention, especially visual, and mental effort. In adults this is the alpha rhythm, and the frequency is 8 to 13 Hz. However the frequency can be higher or lower than this range (often a supra or sub harmonic of alpha frequency) and is called alpha variant rhythm (fast and slow alpha variant rhythm). In children, the normal range of the frequency of the posterior dominant rhythm is age-dependant.</description>

+            <description>EEG rhythm at 7-11 Hz composed of arch-shaped waves occurring over the central or centro-parietal regions of the scalp during wakefulness. Amplitudes varies but is mostly below 50 microV. Blocked or attenuated most clearly by contralateral movement, thought of movement, readiness to move or tactile stimulation.</description>

+            <description>Seizure type frequent in neonates, sometimes referred to as motor automatisms; they may include random and roving eye movements, sucking, chewing motions, tongue protrusion, rowing or swimming or boxing movements of the arms, pedaling and bicycling movements of the lower limbs; apneic seizures are relatively common. Although some subtle seizures are associated with rhythmic ictal EEG discharges, and are clearly epileptic, ictal EEG often does not show typical epileptic activity.</description>

+               <description>PLMS. Periodic limb movement in sleep. Episodes are characterized by brief (0.5- to 5.0-second) lower-extremity movements during sleep, which typically occur at 20- to 40-second intervals, most commonly during the first 3 hours of sleep. The affected individual is usually not aware of the movements or of the transient partial arousals.</description>

+               <description>Episodes characterized by ambulation during sleep; the patient is difficult to arouse during an episode, and is usually amnesic following the episode. Episodes usually occur in the first third of the night during slow wave sleep. Polysomnographic recordings demonstrate 2 abnormalities during the first sleep cycle: frequent, brief, non-behavioral EEG-defined arousals prior to the somnambulistic episode and abnormally low gamma (0.75-2.0 Hz) EEG power on spectral analysis, correlating with high-voltage (hyper-synchronic gamma) waves lasting 10 to 15 s occurring just prior to the movement. This is followed by stage I NREM sleep, and there is no evidence of complete awakening.</description>

+            <description>Characteristic rhythms mostly at 4-5 Hz, recorded most prominently over the posterior regions of the head. Generally alternate, or are intermixed, with alpha rhythm to which they often are harmonically related. Amplitude varies but is frequently close to 50 micro V. Blocked or attenuated by attention, especially visual, and mental effort. Comment: slow alpha variant rhythms should be distinguished from posterior slow waves characteristic of children and adolescents and occasionally seen in young adults.</description>

Small sharp spikes (SSS) of very short duration and low amplitude, often followed by a small theta wave, occurring in the temporal regions during drowsiness and light sleep. They occur on one or both sides (often asynchronously). The main negative and positive components are of about equally spiky character. Rarely seen in children, they are seen most often in adults and the elderly. Two thirds of the patients have a history of epileptic seizures.</description>

It consists of a mixture of frequencies, often predominant in the theta range. The onset may be fairly abrupt with widespread sharp rhythmical theta and occasionally with delta activity. As to the spatial distribution, a maximum of this discharge is usually found over the centroparietal region and especially over the vertex. It may resemble a seizure discharge but is not accompanied by any clinical signs or symptoms.</description>

+               <description>The tongue functions as a dipole, with the tip negative with respect to the base. The artifact produced by the tongue has a broad potential field that drops from frontal to occipital areas, although it is less steep than that produced by eye movement artifacts. The amplitude of the potentials is greater inferiorly than in parasagittal regions; the frequency is variable but usually in the delta range. Chewing and sucking can produce similar artifacts.</description>

+               <description>Respiration can produce 2 kinds of artifacts. One type is in the form of slow and rhythmic activity, synchronous with the body movements of respiration and mechanically affecting the impedance of (usually) one electrode. The other type can be slow or sharp waves that occur synchronously with inhalation or exhalation and involve those electrodes on which the patient is lying.</description>

+               <description>Example for EEG: Far-field potential generated in the heart. The voltage and apparent surface of the artifact vary from derivation to derivation and, consequently, from montage to montage. The artifact is observed best in referential montages using earlobe electrodes A1 and A2. ECG artifact is recognized easily by its rhythmicity/regularity and coincidence with the ECG tracing.</description>

+               <description>Myogenic potentials are the most common artifacts. Frontalis and temporalis muscles (ex..: clenching of jaw muscles) are common causes. Generally, the potentials generated in the muscles are of shorter duration than those generated in the brain. The frequency components are usually beyond 30-50 Hz, and the bursts are arrhythmic.</description>

+                  <description>EEG rhythm between 14 and 40 Hz, which is considered part of the background (ongoing) activity but does not fulfill the criteria of the posterior dominant rhythm. Most characteristically: a rhythm from 14 to 40 Hz recorded over the fronto-central regions of the head during wakefulness. Amplitude of the beta rhythm varies but is mostly below 30 microV. Other beta rhythms are most prominent in other locations or are diffuse.</description>

+            <description>Location can be scored for findings. Semiologic finding can also be characterized by the somatotopic modifier (i.e. the part of the body where it occurs). In this respect, laterality (left, right, symmetric, asymmetric, left greater than right, right greater than left), body part (eyelid, face, arm, leg, trunk, visceral, hemi-) and centricity (axial, proximal limb, distal limb) can be scored.</description>

Usually the patient will be unresponsive when spoken to. Duration is a few seconds to half a minute with very rapid recovery. Although not always available, an EEG would show generalized epileptiform discharges during the event. An absence seizure is by definition a seizure of generalized onset. The word is not synonymous with a blank stare, which also can be encountered with focal onset seizures. Definition from ILAE 2017 Classification of Seizure Types Expanded Version</description>

Eyelid myoclonia can be associated with absences, but also can be motor seizures without a corresponding absence, making them difficult to categorize. The 2017 classification groups them with nonmotor (absence) seizures, which may seem counterintuitive, but the myoclonia in this instance is meant to link with absence, rather than with nonmotor.

+               <description>Seizure semiology refers to the clinical features or signs that are observed during a seizure, such as the type of movements or behaviors exhibited by the person having the seizure, the duration of the seizure, the level of consciousness, and any associated symptoms such as aura or postictal confusion. In other words, seizure semiology describes the physical manifestations of a seizure. Semiology is described according to the ILAE Glossary of Descriptive Terminology for Ictal Semiology (Blume et al., 2001). Besides the name, the semiologic finding can also be characterized by the somatotopic modifier, laterality, body part and centricity. Uses Location-property tags.</description>

Otherwise, use the more specific term (e.g., mnemonic experiential seizure  or hallucinatory experiential seizure). Components of cognition: ++ perception: symbolic conception of sensory information ++ attention: appropriate selection of a principal perception or task ++ emotion: appropriate affective significance of a perception ++ memory: ability to store and retrieve percepts or concepts ++ executive function: anticipation, selection, monitoring of consequences, and initiation of motor activity including praxis, speech.</description>

+                  <description>Prodrome is a preictal phenomenon, and it is defined as a subjective or objective clinical alteration (e.g., ill-localized sensation or agitation) that heralds the onset of an epileptic seizure but does not form part of it (Blume et al., 2001). Therefore, prodrome should be distinguished from aura (which is an ictal phenomenon).</description>

+   <epilogue>The Standardized Computer-based Organized Reporting of EEG (SCORE) is a standard terminology for scalp EEG data assessment designed for use in clinical practice that may also be used for research purposes.
+The SCORE standard defines terms for describing phenomena observed in scalp EEG data. It is also potentially applicable (with some suitable extensions) to EEG recorded in critical care and neonatal settings.
+The SCORE standard received European consensus and has been endorsed by the European Chapter of the International Federation of Clinical Neurophysiology (IFCN) and the International League Against Epilepsy (ILAE) Commission on European Affairs.
+A second revised and extended version of SCORE achieved international consensus.
