title: A patient with myoclonic epilepsy in infancy followed by myoclonic astatic epilepsy.
abstract: Myoclonic epilepsy in infancy (MEI) is a primary generalized epilepsy. According to the literature, the outcome of MEI is usually benign. Here we report a patient who developed myoclonic astatic epilepsy at age four, having been seizure free without antiepileptic drug treatment for 2 years after his recovery from MEI. At age four, a video-EEG-recording showed frequent head nodding (atonic seizures) and myoclonic astatic seizures associated with diffuse spikes or polyspikes and waves. The interictal EEG revealed frequent bursts of generalized 100-200 μV, 2-4 Hz spike-and-slow-wave complexes. Despite a general favorable outcome, more severe epilepsy syndromes may develop after MEI, and mental retardation is sometimes observed. Our case and the previous literature suggest that epilepsies following on from MEI often involve myoclonic seizures.
