Abstract:
Low-frequency deep brain stimulation (DBS) of the pedunculopontine nucleus (PPN) has been reported to improve akinesia and gait difficulties in patients with Parkinson's disease (PD). We report on a patient with PD and L: -dopa refractory gait symptoms who developed detrusor over-activity immediately after right PPN DBS. Proximity between caudal PPN and brainstem structures implicated in control of micturition is a possible explanation.
