PPMI Clinical - Establishing a Deeply Phenotyped PD Cohort

The PPMI study is looking for healthy volunteers, aged 57 or older, to join as a comparison group. You wouldn't be able to join if a close family member (parent, sibling, or child) has Parkinson's disease. Also, if you have other serious brain conditions or certain other medical issues, you might not be eligible. They'll also check your current medications.

If you're a woman of childbearing age, you'll need to confirm you're not pregnant, not breastfeeding, and don't plan to become pregnant during the study. A pregnancy test will be done before certain procedures.

Ticking off these initial points doesn't guarantee you'll be in the study, as the research team will do further checks. The most important thing is that you are willing and able to give your informed consent, meaning you understand the study and agree to participate.

If you decide to take part as a healthy volunteer, you'll be asked to attend several appointments at the study centre. These appointments will involve various assessments, which may include physical check-ups, questionnaires, and perhaps some simple tasks to assess your movements or thinking. You would also have a special brain scan called a SPECT scan. Some participants might be asked to have a lumbar puncture (spinal tap), where a small amount of fluid is taken from your spine for analysis – this would only happen if it's considered safe for you. You might also be asked to try out digital tools, like mobile apps or wearable devices, to track certain activities at home.

Depending on the specific study activities, you might need to temporarily stop taking certain medications before scans or other procedures. This will always be discussed with you by the study team. Overall, you'll be followed for a period of time, with regular visits to track changes. The study is part of a larger programme, and you might be invited to take part in other related PPMI activities over time.
