Michael J. Fox talks Parkinson’s disease and how it impacted his wife

Michael J. Fox said going public with his Parkinson's diagnosis was 'really hard' on his wife Tracy Pollan and that she 'went through hell' for him.

Fox told Tracy Pollan, 'I have to go all the way here. No half measures,' when deciding to be open about his condition.

Fox returned to acting in the series 'Shrinking,' where he plays a character battling Parkinson's disease alongside Harrison Ford.

Fox's Parkinson's diagnosis began in 1991 when he was 29 years old.
