Michael J Fox has opened up about his Parkinson's diagnosis and why he was reluctant to tell fans. You can watch it here:

The 61-year-old has since spoken out about why he didn't tell fans about his diagnosis until seven years later, in 1998.

"Most people with Parkinson's start to develop symptoms when they're over 50, although around one in 20 people with the condition first experience symptoms when they're under 40," the website continues.

The actor stated: "My fear was that if they knew I had an illness, a condition, that they wouldn't be able to laugh.

"You know it was a really strange period of time because over a period of seven years that I kept it to myself."

However, when Fox finally did open up to people about his condition, he discovered they were 'incredibly receptive' and 'incredibly supportive'.

The actor also discovered his fear of the audience not feeling able to laugh was quickly put at ease.

"The audience did, in fact, continue to laugh and continue to watch my work," he continued.

What's more, speaking out about his diagnosis also led to a 'whole opportunity' opening up.

"I started talking to scientists and they started telling me the science is ahead of the money. We know more than we can pay for. We understand more than we're getting. and i thought well, I can do that," Fox added.

The Michael J. Fox Foundation 'is dedicated to finding a cure for Parkinson's disease through an aggressively funded research agenda and to ensuring the development of improved therapies for those living with Parkinson's today' and exists 'to accelerate the next generation of Parkinson’s disease (PD) treatments'.
