Seven boys aged between 14 months and 13 years with focal or multifocal partial epilepsy had very unusual seizures, characterized by series of periodic bilateral spasms. These consisted of a brief, complex movement of slight to severe intensity, mainly involving the axial muscles, with raising of the shoulders, adversion of the eyes and head, often with rictus-type facial grimaces and occasional stretching of the legs and emission of guttural sound. The ictal EEG showed a pattern of periodic complexes, characterized by a slow wave with superimposed fast activity. This form of epileptic seizure is resistant to treatment and is found only in patients affected by a brain disease consisting of a fixed or progressive encephalopathy. These observations document the existence of a rare form of seizure or epileptic event, not yet included in the International Classification of epileptic seizures and clinically relevant because of its diagnostic and prognostic implications.
