| gelastic seizure | A seizure characterised by laughing. This seizure type is often accompanied by hypothalamic lesions, such as hamartomas. (05 Mar 2000) |
| generalised seizure | <neurology> A type of seizure that results in loss of consciousness, generalised muscle contractions, urinary incontinence, tongue biting and a post-ictal state (confusion and lethargy) following cessation of the seizure. Synonym: grand-mal seizure. See: epilepsy. (03 Jul 1999) |
| generalised tonic-clonic seizure | <neurology> A type of seizure that results in loss of consciousness, generalised muscle contractions, urinary incontinence, tongue biting and a post-ictal state (confusion and lethargy) following cessation of the seizure. Synonym: grand-mal seizure. See: epilepsy. (03 Jul 1999) |
| versive seizure | A partial seizure associated with head and eye deviation to one side. (05 Mar 2000) |
| partial seizure | <neurology> A brief temporary alteration in movement, sensation or autonomic nerve function caused by abnormal electrical activity in a localised area of the brain. Focal seizures (i.e. Partial or Jacksonian seizures) usually cause no change in awareness or alertness. An example of a focal (partial) seizure would be rhythmic muscle contractions in one area of the body: lip smacking, mouth movements, drooling, head turning, eye movements or seemingly purposeful movements (for example picking at clothes). Other presentations may be strictly sensory with abnormal numbness, tingling or a crawling sensation to the skin. More unusual symptoms include changes in speech, thought, personality, mood, sensation of deja vu or hallucinations. (27 Sep 1997) |

| grand mal seizure | A type of seizure that results in loss of consciousness, generalised muscle contractions, urinary incontinence, tongue biting and a post-ictal state (confusion and lethargy) following cessation of the seizure. Also referred to as a grand-mal seizure. See: epilepsy. (27 Sep 1997) |
| petit mal seizure | An absence seizure. (05 Mar 2000) |
| clonic seizure | A seizure characterised by repetitive rhythmical jerking of all or part of the body. (05 Mar 2000) |
| CO2-withdrawal seizure test | Utilization of hyperventilation to demonstrate abnormalities in the brain waves or even to precipitate a convulsion. (05 Mar 2000) |
| motor | <neurology, physiology> A muscle, nerve or centre that effects or produces movement. (18 Nov 1997) |
