Purpose
In the advanced stages of Parkinson Disease deep brain stimulation of the subthalamic nucleus (STN DBS) is the next therapeutic option. Despite the beneficial motor effects there are important negative side-effects of STN DBS. Our hypothesis is that changes in cognition and behavior during STN DBS are related to stimulation of the non-motor parts of the STN.
The primary objective is to avoid cognitive and affective side effects by selective stimulation of the STN motor part.
The main objective of this feasibility study is to measure the patients burden and to test the technical feasibility.
Intervention:
The intervention is an expansion of the classical STN DBS procedure. The targeting using the multichannel registration system by stimulation of the motor cortex and registration of the subthalamic nucleus will be added to the procedure. For this procedure, it is necessary to place a subdural strip under the skull.
