Bilateral Subthalamic Stimulation in PD Patients With Impulse Control Disorders - STIMPulseControl

This study (called STIMPulseControl) is testing whether deep brain stimulation (DBS) surgery — which uses implanted electrodes to regulate brain signals — can reduce compulsive behaviors (like gambling, hypersexuality, or binge eating) in people with Parkinson's disease who have developed these problems, often as a side effect of their medications. **You may be eligible if...** - You are 70 or younger and have been diagnosed with Parkinson's disease for at least 4 years - You have moderate to severe impulse control problems (like compulsive gambling, shopping, eating, or hypersexuality) as measured by a validated scale - Your Parkinson's motor symptoms are responsive to levodopa medication - Your general health and cognitive function are adequate for surgery **You may NOT be eligible if...** - You have severe dementia or major psychiatric illness that would prevent surgery - You are above 70 years of age - Your Parkinson's does not respond well to levodopa - You have other neurological conditions or implanted devices incompatible with the stimulator Talk to your doctor to see if this trial is right for you.
