Clinical-electrophysiological correlation of tremor and myoclonus in a kindred with the N279K tau mutation.

Abstract excerpt

We used electrophysiological methods to study the hyperkinetic movement disorders in a pallido-ponto-nigral degeneration (PPND) family, which harbors the N279K tau gene mutation. Our purpose was to: (1). characterize the tremor patterns, (2). characterize the myoclonus physiology, (3). determine whether electrophysiology can detect abnormalities in asymptomatic cases. In PPND, we found that the activation tremors...
