Welcome to the Cholinesterase Inhibitors to Prevent Falls in Parkinson’s Trial. This is a medical research trial that is examining whether drugs normally used to treat people with memory problems can be used to reduce the number of falls that people with Parkinson’s experience.

We are currently recruiting participants across 26 NHS hospital sites in the UK. We need to enrol 600 people with Parkinson’s who have experienced a fall in the past year. If you would like to participate in the trial, please go to the Taking Part page for more information and to keep up to date with the trial, please sign up to our mailing list.
