An
epileptic seizure, occasionally referred to as a
fit, is defined as a transient symptom of "abnormal excessive or
synchronous neuronal activity in the brain".
The outward effect can be as dramatic as a wild thrashing movement or as mild as a brief loss of awareness. It can manifest as an alteration in
mental state,
tonic or
clonic movements,
convulsions, and various other psychic symptoms. Sometimes it is not accompanied by convulsions but a full body "slump", where the person simply will lose body control and slump to the ground. The medical syndrome of recurrent, unprovoked seizures is termed
epilepsy, but seizures can occur in people who do not have epilepsy. For more information, see
non-epileptic seizure.
