We investigated the effect of pallidal deep brain stimulation (GPi-DBS) in dystonia on cognition, mood, and quality of life and also assessed if DYT1 gene status influenced cognitive outcome following GPi-DBS. Fourteen patients with primary generalized dystonia (PGD) were assessed, measuring their estimated premorbid and current IQ, memory for words and(More)

Although a range of psychiatric and behavioral problems have been documented following deep brain stimulation, the short-term effects of subthalamic nucleus stimulation on patients' mood have only been investigated in a few studies. Our(More)
