This study is about Parkinson's disease, a brain disorder that affects movement. The research will examine how the disease progresses over 12 months. Participants will use wearable devices to track sleep and movement. **Parkinson's disease (PD)** is a disorder that affects the brain and causes shaking, stiffness, and difficulty with walking, balance, and coordination. The study is **observational**, meaning researchers will watch and record data without giving any treatment. Participants need to be between 18 to 85 years old. They must be generally healthy, aside from having Parkinson's, and able to follow study procedures both in the clinic and at home. People who can't commit to the 12-month duration or have other conditions that could impact the study won't be able to join. This includes those with a history of frequent falls or substance use issues. The study won't be testing any new treatments, so there's no risk of side effects from a new drug.

• The study lasts for 12 months.
• No new treatments will be given.
• Participants must be able to commit to regular data collection activities.
