Preoperative Glymphatic Asymmetry Is Associated with Motor Outcomes Following STN-DBS in Parkinson's Disease.
BACKGROUND Interindividual variability in motor outcomes after subthalamic nucleus deep brain stimulation (STN-DBS) in Parkinson's disease (PD) remains incompletely understood. Glymphatic-related imaging abnormalities have been reported in PD, but their relevance to neuromodulation response is unclear. OBJECTIVES To...
