CONCURRENT NOCTURNAL AND DIURNAL PAROXYSMAL DYSTONIA

The authors describe a case of a 15-year-old girl who presented with a progressive sequence of nocturnal dystonic episodes, generalized seiz ures, and diurnal dystonic episodes. A diagnosis of nocturnal paroxysm al dystonia has been proposed in view of the association between noctu rnal episodes and epileptic seizures, while the diurnal episodes are a typical. Neurophysiological data recorded during critical episodes are reported. A linkage between dystonic attacks and epilepsy is hypothes ized.
