| tonic epilepsy | An attack in which the body is rigid. (05 Mar 2000) |
|---|---|
| tonic pupil | Usually a unilateral abnormality of the eye characterised by slow pupillary constriction to light and in which there is a delayed reaction to changes in accommodation and convergence. The affected pupil is usually larger. (12 Dec 1998) |
| tonic reflex | The occurrence of an appreciable interval after the production of a reflex before relaxation, e.g., the leg remains up for a time after a knee jerk. Synonym: Gordon's symptom. (05 Mar 2000) |
| tonic spasm | A continuous involuntary muscular contraction. (05 Mar 2000) |
| absence seizure | <neurology> A type of seizure that in contrast to the grand mal seizure, are noted for their brevity and for the degree of loss of awareness (brief staring spell) accompanied by minimal motor manifestations. A common form of childhood epilepsy. (06 Oct 1997) |
| akinetic seizure | Seizure characterised by sudden loss of muscle tone. Synonym: akinetic seizure. (05 Mar 2000) |
| atonic seizure | Seizure characterised by sudden loss of muscle tone. Synonym: akinetic seizure. (05 Mar 2000) |
| atypical absence seizure | An absence seizure associated with an EEG pattern of irregular or slow spike and wave at less than 2.5 Hz or paroxysmal fast activity on an abnormally slow background EEG. (05 Mar 2000) |
| audiogenic seizure | A reflex seizure precipitated by loud noises, rare in humans. Audiogenic seizures in rodents are an animal model of epilepsy. (05 Mar 2000) |
| major motor seizure | A grand mal seizure or other convulsive seizure. (05 Mar 2000) |
| 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) |
| 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) |
