Early myoclonic encephalopathy (EME) is a rare malignant epileptic syndrome. The erratic myoclonus with or without focal motor seizures, onset before 3 months of age, and persistent suppression-burst pattern in electroencephalograph (EEG) are accepted as the diagnostic criteria for EME. The pathogenesis of EME is variable, with structural, metabolic, and genetic abnormalities all playing a role. Associated metabolic abnormalities are frequently described. In particular, nonketotic hyperglycinemia has been associated with a large number of cases.
