Parkinson's Disease study: Deep Brain Stimulation
Official title Adaptive Neurostimulation to Restore Sleep in Parkinson's Disease (Aim 2)
ClinicalTrials.gov ID: NCT05070013
What this study is testing
- What it's testing
- The study wants to find out if adaptive stimulation of the subthalamic nucleus can change sleep episode maintenance and improve sleep quality in people with Parkinson's disease.
- Who it's for
- Adults with Parkinson's disease who still have motor symptoms despite medication and are already scheduled for deep brain stimulator implantation.
- What's involved
- Before surgery, sleep will be tracked with questionnaires and a watch‑like device. About four months after implantation, each participant will undergo two separate one‑week periods of deep brain stimulation and one one‑week period with no stimulation, in random order, while sleep is continuously monitored.
- Time commitment
- The study lasts about four months, with visits before surgery, the implantation surgery, and three one‑week monitoring sessions after surgery.
This is a blinded study.
