Abstract
Three cases of myoclonic epilepsy presenting in adolescence are described. Seizures were uninfluenced by treatment with carbamazepine. Substitution of sodium valproate in early adult life resulted in all becoming seizure-free. A high degree of clinical awareness is required in making the correct diagnosis and in choosing appropriate therapy for this form of epilepsy which can present with generalised tonic-clonic or partial seizures.
