Michael J. Fox has said that the cure for Parkinson's Disease is 'closer than it's ever been'.
The much-loved actor was just 29 when he was diagnosed with the degenerative condition after developing tell-tale symptoms - notably a nervous twitching of the fingers - while filming romantic comedy Doc Hollywood in 1991.
