Childhood absence epilepsy

a generalised epilepsy syndrome characterised by the onset of absence seizures in childhood, typically at age six or seven years. There is a strong genetic predisposition and girls are affected more often than boys. Eeg reveals generalised 3 hz spike-wave activity on a normal background. Prognosis for remission is good if the patient does not also have generalised tonic-clonic seizures.

See: absence.

Synonym: petit mal epilepsy, pyknolepsy.
