Disease Duration Differentiates Freezing of Gait Response to Subthalamic and Nigral Stimulation for Parkinson's Disease in an Exploratory Multicenter Controlled Trial

BACKGROUND: Freezing of gait (FoG) belongs to most pressing unmet symptoms in the treatment of Parkinson's disease. OBJECTIVES: To explore whether combined subthalamic and nigral (STN + SNr) deep brain stimulation improves FoG compared with optimized STN stimulation alone; to ide...

Inconsistent subthalamic local field potential beta activity amid in- and antiphasic neuronal bursts

Abstract Elevated subthalamic (STN) beta (12–32 Hz) local field potentials (LFP) are a hallmark of Parkinson’s disease and closely tied to synchronized spiking. The biomarker guides deep brain stimulation (DBS) lead implantation and is under investigation to inform DBS programmin...
