Could this be for you?

Answer for yourself. This is not a decision: only the study team can say whether you can take part.

  • Are you between 40 and 85 years old?
  • Has a doctor told you that you have a different condition with similar signs, such as multiple system atrophy or progressive supranuclear palsy?
  • Which medicine do you take for Parkinson's disease now?
  • Do you have dementia, or serious problems with memory and thinking?
