The Parkinson's Big Brother House

This week's Healthy Conversation takes place in a small house in Bristol where an extraordinary experiment is taking place which could help find new drugs to treat Parkinson's. The house is packed with cameras and sensors which record the every move of people who come to stay for five days, as researchers try to find a better way of measuring the progression of Parkinson's. Rory Cellan-Jones talks to Dr Alan Whone and Dr Cathy Morgan about the Parkinson's Big Brother House and what they hope to achieve with their project.
