== Principles for terms and definitions ==

In developing the “lexique” of this report, the following principles have been adopted and applied.
Terms and definitions should
# Contain features that distinguish or modify seizure entities.
# Be descriptive of the phenomena involved.
# Comply with terminology of clinical neuroscience.
# Use current terminology and definitions wherever possible.
# Contain new terms only if necessary.
# Be easily translatable to other languages.
# Be readily understood and used by potential users.

== General terms ==
1. SEMIOLOGY

That branch of linguistics concerned with signs and symptoms.

2. EPILEPTIC SEIZURE

Manifestation(s) of epileptic (excessive and/or hyper- synchronous), usually self-limited activity of neurons in the brain.

3. ICTUS

A sudden neurologic occurrence such as a stroke or an epileptic seizure.

4. EPILEPSY
* Epileptic Disorder: A chronic neurologic condition characterized by recurrent epileptic seizures.
* Epilepsies: Those conditions involving chronic recurrent epileptic seizures that can be considered epileptic disorders.

5. FOCAL (syn. partial),

A seizure whose initial semiology indicates, or is consistent with, initial activation of only part of one cerebral hemisphere.

6. GENERALIZED (syn. bilateral)

A seizure whose initial semiology indicates, or is consistent with, more than minimal involvement of both cerebral hemispheres.

7. CONVULSION

Primarily a lay term. Episodes of excessive, abnormal muscle contractions, usually bilateral, which may be sustained or interrupted.

== Terms describing epileptic seizure semiology ==

These are descriptors of seizures unless specified otherwise.

=== MOTOR ===

Involves musculature in any form. The motor event could consist of an increase (positive) or decrease (negative) in muscle contraction to produce a movement.
Unless noted, the following terms are adjectives modifying “motor seizure” or “seizure” (e.g., “tonic motor seizure or dystonic seizure”), and whose definitions can usually be understood as prefaced by “refers to . . .”.

==== ELEMENTARY MOTOR ====

A single type of contraction of a muscle or group of muscles that is usually stereotyped and not decomposable into phases. (However, see tonic–clonic, an elementary motor sequence).

1.1.1 TONIC

A sustained increase in muscle contraction lasting a few seconds to minutes.

1.1.1.1 EPILEPTIC SPASM (Formerly Infantile Spasm)

Noun: A sudden flexion, extension, or mixed extension–flexion of predominantly proximal and truncal muscles that is usually more sustained than a myoclonic movement but not so sustained as a tonic seizure (i.e., ∼1 s). Limited forms may occur: grimacing, head nodding. Epileptic spasms frequently occur in clusters.

1.1.1.2 POSTURAL

Adoption of a posture that may be bilaterally symmetric or asymmetric (as in a “fencing posture”).

1.1.1.2.1 VERSIVE

A sustained, forced conjugate ocular, cephalic, and/or truncal rotation or lateral deviation from the midline.

1.1.1.2.2 DYSTONIC

Sustained contractions of both agonist and antagonist muscles producing athetoid or twisting movements, which, when prolonged, may produce abnormal postures.

1.1.2 MYOCLONIC (adjective); MYOCLONUS (noun)

Sudden, brief (<100 ms) involuntary single or multiple contraction(s) of muscles(s) or muscle groups of variable topography (axial, proximal limb, distal).

1.1.2.1 NEGATIVE MYOCLONIC

Interruption of tonic muscular activity for <500 ms without evidence of preceding myoclonia.

1.1.2.2 CLONIC

Myoclonus that is regularly repetitive, involves the same muscle groups, at a frequency of ∼2–3 c/s, and is prolonged. Synonym: rhythmic myoclonus.

1.1.2.2.1 JACKSONIAN MARCH

Noun: Traditional term indicating spread of clonic movements through contiguous body parts unilaterally.

1.1.3 TONIC–CLONIC

A sequence consisting of a tonic followed by a clonic phase. Variants such as clonic–tonic–clonic may be seen.

1.1.3.1 GENERALIZED TONIC–CLONIC SEIZURE (syn. bilateral tonic–clonic seizure) (Formerly “Grand Mal” Seizure)

Noun: Bilateral symmetric tonic contraction and then bilateral clonic contractions of somatic muscles, usually associated with autonomic phenomena.

1.1.4 ATONIC

Sudden loss or diminution of muscle tone without ap- parent preceding myoclonic or tonic event lasting 􏰃1 to 2 s, involving head, trunk, jaw, or limb musculature.

1.1.5 ASTATIC

Loss of erect posture that results from an atonic, myoclonic, or tonic mechanism. Synonym: drop attack.

1.1.6 SYNCHRONOUS (Asynchronous)

Motor events occurring (not) at the same time or at the same rate in sets of body parts.

==== AUTOMATISM ====

Noun: A more or less coordinated, repetitive, motor activity usually occurring when cognition is impaired and for which the subject is usually amnesic afterward. This often resembles a voluntary movement and may consist of an inappropriate continuation of ongoing preictal motor activity.

The following adjectives are usually employed to modify “automatism.”

1.2.1 OROALIMENTARY

Lip smacking, lip pursing, chewing, licking, tooth grinding, or swallowing.

1.2.2 MIMETIC

Facial expression suggesting an emotional state, often fear.

1.2.3 MANUAL OR PEDAL
# Indicates principally distal components, bilateral or unilateral.
# Fumbling, tapping, manipulating movements.

1.2.4 GESTURAL

Often unilateral.
# Fumbling or exploratory movements with the hand, directed toward self or environment.
# Movements resembling those intended to lend fur- ther emotional tone to speech.

1.2.5 HYPERKINETIC
# Involves predominantly proximal limb or axial muscles producing irregular sequential ballistic movements, such as pedaling, pelvic thrusting, thrashing, rocking movements.
# Increase in rate of ongoing movements or inappro- priately rapid performance of a movement.

1.2.6 HYPOKINETIC

A decrease in amplitude and/or rate or arrest of ongoing motor activity.

1.2.7 DYSPHASIC

Impaired communication involving language without dysfunction of relevant primary motor or sensory pathways, manifested as impaired comprehension, anomia, paraphasic errors, or a combination of these.

1.2.8 DYSPRAXIC

Inability to perform learned movements spontaneously or on command or imitation despite intact relevant motor and sensory systems and adequate comprehension and cooperation.

1.2.9 GELASTIC

Bursts of laughter or giggling, usually without an appropriate affective tone.

1.2.14 INTERACTIVE

Not stereotyped, involve more than self, environmentally influenced.

=== NONMOTOR ===

2.1 AURA

2.2.2 EXPERIENTIAL

Affective, mnemonic, or composite perceptual phenomena including illusory or composite hallucinatory events; these may appear alone or in combination. Included are feelings of depersonalization. These phenomena have subjective qualities similar to those experienced in life but are recognized by the subject as occurring outside of actual context.
