Conditions

Procedure: bilateral high frequency deep brainstimulation of the subthalamic nucleus combined with best medical treatment
Registration Number
NCT06498349
Lead Sponsor
University of Kiel
Brief Summary

The focus of the study is on patients Parkinson's disease showing as well behavioral disorders that can be described as pathological and are summarized under the term impulse control disorder (ICD). Changes in behavior and also pathological disorders are a common side effect of treatment for Parkinson's disease. The goal of this academic study is to compare the effect of surgical (deep brain stimulation, DBS) treatment combined with a coordinated and adapted best medical treatment (BMT) to be compared with the effect of optimized best medical treatment (BMT) alone. The stimulation arm (DBS+BMT) as well as the medication arm (BMT only) will be monitored according to clinical routine. Participants will have to agree to be randomly assigned to either deep brain stimulation in combination with the best medical treatment (DBS group) or the best medical treatment alone (BMT group). Participants will have to come regularly according to clinical routine to the clinic and complete various questionaires and scales for the study.

An intra-group comparison will be performed between the individual patient's safety speech outcome of Parkinson's disease Dysarthria Compound Score (PD-DCS) The PD-DCS is a speech acoustic summary measure of the main speech affected domains in PD, namely monopitch, monoloudness, imprecise consonants, inappropriate silences, harsh/breathy voice, and speech timing abnormalities. Acoustic proxy measures of these perceptual speech domains can be extracted from speech using modern acoustic speech analysis.
