ABSTRACT
@#Objective To explore the various types of progressive myoclonus epilepsy seizure characteristics, diagnostic strategies, and pathological features.Methods12 cases of progressive myoclonus epilepsy were analyzed with the clinical characteristics, the routine laboratory examinations, the pathological examination by light and electron microscopy to extra cranial.Results12 cases carried out routine examinations, neural electrophysiological examinations and physical examinations. The result showed that there 5 patients diagnosed with Neuronal Ceroid Lipofuscinoses, 5 patients with MERRF, 1 patient with Lafora Disease, 1 patient with Unverricht-Lundborg disease.ConclusionProgressive myoclonus epilepsy is a group of rare myoclonus epilepsy syndrome.
