Safety and Feasibility of Using Low Frequency Deep Brain Stimulation of the Subthalamic Nucleus to Improve Cognitive Performance in Patients With Parkinson's Disease
Safety and Feasibility of Using Low Frequency Deep Brain Stimulation of the Subthalamic Nucleus to Improve Cognitive Performance in Patients With Parkinson's Disease
Prospective trial of low frequency deep brain stimulation of the ventral subthalamic nucleus to improve cognitive performance in patients with advanced Parkinson's disease. All study participants have undergone DBS implantation surgery as part of their routine care for motor manifestations of Parkinson's disease. In this study, a temporary low frequency period of stimulation will be applied to determine its effects on cognition.
In this randomized cross-over pilot study, our primary aim was to determine the effect of theta (5 Hz), and gamma (130 Hz) frequency stimulation in the ventral STN on cognitive control in patients with PD. This study provides a first look at frequency dependent modulation of cognitive function and provides important insights into the utility of DBS for non-motor symptoms of PD and other neuropsychiatric disorders.
