The MARKERS-NDD study looks for early signs of neurodegenerative diseases (NDDs), like Parkinson's, by collecting information over time from normal medical check-ups. **Neurodegenerative diseases** are illnesses where parts of the brain slowly stop working. The study uses different tests like brain scans, movement checks, and blood tests. These help doctors see how the disease is progressing and can even use smart computer programs (AI) to find new ways to diagnose and predict these diseases.
**Key Points:**
- The study is observational, meaning it watches and records things without changing them. No new treatments are given.
- Participants must be willing to join, understand the process, and sign a consent form.
- There's no age limit, and you can join even if you have other health issues, as long as you can take the tests.
