title: Electroencephalographic findings of hereditary dentatorubral-pallidoluysian atrophy (DRPLA).
abstract: The electroencephalograms (EEGs) of 22 patients suffering from hereditary DRPLA were studied. Epileptoform patterns were observed in 14 patients (63.6%) with epileptic seizures. The epileptoform patterns most frequently observed were those atypical spike-wave complexes. Slow wave bursts were seen in 18 patients (81.8%). Photosensitivity was revealed in six (27.3%) patients, all of whom presented progressive myoclonus epilepsy (PME) syndrome. Abnormal background activity was evident in 17 (77.3%) patients. These abnormalities in EEG were more severe in patients in the PME type than those of the A (ataxia) and AE (ataxia and epilepsy) types.
