Parkinson's sufferers 'face regular discrimination'

Nearly half of those with Parkinson's face regular discrimination, such as having their symptoms mistaken for drunkenness, a survey suggests.

The survey of more than 2,000 people was commissioned by charity Parkinson's UK.

One person in 500 people is affected by the condition in Britain.

Parkinson's sufferer Mark Worsfold told the BBC's Graham Satchell about the prejudice and discrimination he encounters.
