title: [Myoclonic epilepsy with non-progressive encephalopathy].
abstract: We report 6 cases of particular type of myoclonic epilepsy with non-progressive encephalopathy. It consists of a syndrome characterized by an onset of seizures in the first year of life, frequent myoclonic status, generalized spikes and waves on EEG and an unfavourable outcome with encephalopathy. At the beginning, the diagnosis is difficult, the symptomatology later suggests a progressive encephalopathy. In the present study, a detailed analysis of the early electroencephalographic aspects and of the arguments in favour of a non-progressive encephalopathy is proposed. Hypothesis of perinatal vascular lesions mainly involving the central areas is forwarded.
