Pallidal stimulation-induced psychosis and suicidality in Parkinson’s disease
Abstract
Neuropsychiatric adverse events have been previously reported following deep brain stimulation (DBS) for Parkinson’s disease (PD). Most cases described have involved DBS of the subthalamic nucleus (STN). We report a unique case of acute-onset and reversible psychosis, suicidality, and depressive symptoms following DBS of the globus pallidus internus (GPi) and review the relevant literature.
