This study looks at how a drug called Lemborexant might help people with Parkinson's disease who have trouble moving and sleeping. Parkinson's is a disease that affects movement, causing slow movements, shaking, and stiffness. Many people with Parkinson's also have trouble sleeping, which can make things worse.
Lemborexant is a type of medicine that blocks something in the brain called orexin, which helps with sleep and movement. The study will see if taking Lemborexant can help with these problems. People in the study will take 5 mg of Lemborexant or a placebo (a fake pill) each night for 28 days. They will visit the study team four times during this period to check on their progress.
- Study Length: 28 days with 4 visits.
- Eligibility: Must be 50 or older with Parkinson's and sleep problems.
- Compensation: Participants will receive benefits for taking part.
