A seizure is a sudden disruption of the brain's normal electrical activity accompanied by altered consciousness and/or other neurological and behavioral abnormalities. Epilepsy is a condition characterized by recurrent seizures that may include...

Seizures A temporary series of uncontrollable muscle spasms brought on by unusual electrical activity in the brain. Also known as convulsion, clonic seizure, or tonic-clonic seizure. A seizure is characterized by a sudden episode of un- controllable...
