Brief summary
Although deep brain stimulation of the subthalamic nucleus(STN DBS) has become the surgical treatment of choice for Parkinson's disease(PD), a consensus on the timing of surgery is lacking. This study is intended to demonstrate that early, compared with delayed, introduction of STN DBS is more beneficial for PD patients who have developed motor complications.
Detailed description
In this prospective study, 200 PD patients will be recruited for STN DBS over three years, including 133 with motor complications existing for more than three years (late complication group) and 67 less than three years (early complication group). To make a comparison of therapeutic efficacy between the two groups, motor and non-motor symptoms will be assessed using specific rating scales and questionnaires.
