Parkinson's VIP


  • People diagnosed with Parkinson’s;
  • Healthy individuals unaffected by any neurological disease.

What: You can take part in our study using your own computer at home. If you decide to participate, you will be asked to complete a few online questionnaires about your health and then perform a series of simple vision tests. Vision tests include several optical illusions, each designed to challenge a different vision process in the brain to find out which parts of vision are most affected.

Why: For some people with Parkinson’s visual symptoms take the form of hallucinations. For others it can be difficulties with everyday tasks such as reading the newspaper or following maps. These problems are not well studied in Parkinson’s and there is a real need to understand these symptoms better. Our study will measure changes in vision in a large number of people with Parkinson’s and healthy volunteers, via the internet. Our aim is to work out what sometimes goes wrong with vision in people with Parkinson’s.
