Predictive Factors for Therapeutic Response of Subthalamic Stimulation on Quality of Live in Parkinson's Disease

University Hospital, Lille·observational·Posted Feb 10, 2015·Updated Apr 22, 2026

In Brief

An observational study evaluating patients with Parkinson's disease for Parkinson's Disease. Completed, enrolled 700 participants across 15 sites.

Detailed Summary

This study identify preoperative predictors of response to subthalamic stimulation at 1 year, 3 years and 5 years in terms of quality of life, from a broad prospective multicenter study French with standardized collection of clinical data , imaging and genetic . The investigators want to identify factors that predict the improvement of quality of life for one year corresponding to a decrease of PDQ39 score of at least 20 %. They believe that improvement would be less likely to become zero to 3 or 5 years and question the indication of the subthalamic stimulation (risks and costs). This is part of a process of "personalization" of the therapeutic care that is of any interest to the subthalamic stimulation. It is a therapeutic option that could be dangerous if patient selection is not optimal , and expensive, if the benefit is not large enough to reduce the number of medications and hospitalizations medium term . In addition, it will quantify the improvement of quality of life in the longer term and harmonize national assessments .
