Cortical thickness in visuo-motor areas is related to motor outcomes after STN DBS for Parkinson's disease

Introduction Deep brain stimulation (DBS) is a widely accepted therapy for Parkinson's disease. While outcome predictors such as levodopa-response are well established, there remains a need for objective and unbiased predictors in clinical practice. We performed an exploratory study to examine whether cortical thickness, derived from preoperative MRI, correlates with postoperative outcome. Methods Using freesurfer, we retrospectively measured...
