Abstract

Parkinson’s disease (PD) and Essential Tremor (ET) are progressive conditions with high world-wide prevalence. Deep Brain Stimulation (DBS) is an accepted therapy, yet the underlying therapeutic neurophysiological mechanisms are not well understood. We studied the wash in/out times of DBS therapy for tremor suppression and speech side-effect to gain further insight into these mechanisms and to establish guidelines for future research. Methods: After obtaining informed consent, 10 patients (ET or tremor-dominant PD) with DBS were recruited into our study from the medical registers of two neurologists. Over the course of a two hour assessment, DBS amplitude was systematically varied between ..
