Also called a FIT, this is a sudden burst of uncontrolled electrical activity in the BRAIN. A seizure may be generalised or partial: in the former, abnormal electrical activity may affect the whole brain, resulting in abnormal movements of many or all parts of the body and a period of unconsciousness. This is characteristic of EPILEPSY; in partial seizures, abnormal electrical activity occurs in one part of the brain. HALLUCINATIONS may occur and localised symptoms include muscular twitching or a tingling sensation in a small area of the face, arm, leg or trunk. Different neurological or medical disorders may cause seizures: for example, STROKE, brain tumour, head injury, infection or metabolic disturbance (see METABOLISM; METABOLIC DISORDERS). People dependent on alcohol may suffer seizures if they stop drinking. Treatment is of the underlying condition coupled with antiepileptic drugs such as CARBAMAZEPINE, lamotrigine, SODIUM VALPROATE or PHENYTOIN SODIUM (see EPILEPSY).
