Benign myoclonic epilepsy in infants: electroclinical features and long-term follow-up of 34 patients.

Purpose: Benign myoclonic epilepsy in infants (BMEI) is a rare epileptic syndrome characterized only by generalized myoclonic seizures (MSs) in normal children during the first 2 years. Our aim was to assess the electroclinical features and the follow-up of this syndrome.

Methods: BMEI was confirmed by electroencephalogram (EEG) in four neuropediatric units in France between 1981 and 2002.
