| seizure | <clinical sign, neurology> A sudden attack or convulsion due to involuntary electrical activity in the brain. It is due to an uncontrolled burst of electrical activity in the brain that can result in a wide variety of clinical manifestations such as: muscle twitches, staring, tongue biting, urination, loss of consciousness and total body shaking. Examples include: focal seizure, absence seizure, partial seizure, psychomotor seizure, petit-mal seizure and grand-mal seizures. (27 Sep 1997) |
|---|---|
| seizure, causes of | Known causes of seizures include head injuries, brain tumours, lead poisoning, maldevelopment of the brain, genetic and infectious illnesses. But in fully half of the patients with seizures, no cause can be found. (12 Dec 1998) |
| pyridoxine dependency with seizure | An inherited disorder (autosomal recessive) apparently associated with deficient brain type I glutamate decarboxylase; seizures can be controlled with vitamin B6. (05 Mar 2000) |
| simple partial seizure | A partial seizure that is not associated with impairment of consciousness. (05 Mar 2000) |
| subclinical seizure | A seizure detected by EEG, which has no clinical correlate, i.e., an EEG seizure alone or an electrical seizure alone. Synonym: electrographic seizure. (05 Mar 2000) |
| nonconvulsive seizure | A seizure without clonic or tonic activity or other convulsive motor activity. See: complex partial seizure, absence seizure. (05 Mar 2000) |
| nonepileptic seizure | <neurology> Any behaviour that resembles a seizure, but is not epileptic, i.e., not associated with abnormal cerebral EEG activity. See: psychogenic seizure. (05 Mar 2000) |
| early seizure | A seizure occurring within one week after craniocerebral trauma. (05 Mar 2000) |
| electrographic seizure | A seizure detected by EEG, which has no clinical correlate, i.e., an EEG seizure alone or an electrical seizure alone. Synonym: electrographic seizure. (05 Mar 2000) |
| 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) |
| tonic seizure | Sustained contractures of skeletal muscle as occur during convulsions. Synonym: tonic convulsion. (05 Mar 2000) |
| epileptic seizure | A seizure that is caused by epilepsy. (05 Mar 2000) |
| Jacksonian seizure | 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) |
| febrile seizure | <neurology, paediatrics> A convulsion that occurs secondary to a rapid increase in body temperature. Common in infants under two years of age. (27 Sep 1997) |
| focal motor seizure | A simple partial seizure with localised motor activity. (05 Mar 2000) |
