Diagnosed with Parkinson’s 15 years ago, Michael J. Fox hasn’t let the ravages of the disease take his attention from what’s really important: His wife, kids and quest for a cure.
“I’m so blessed with a great family, and I’ve had success in my career,” the actor, who’s been campaigning for candidates who support embryonic stem-cell research, tells PEOPLE in its new issue. “I feel this is a really unique opportunity for me to help out and try to effect change.”
Fox, 45, says his condition is now so much a part of his life that even his kids with wife Tracy Pollan – Sam, 17; twins Aquinnah and Schuyler, 11; and Esme, 5 – barely mention it anymore. “They know it so intimately,” he says. “It would be like asking your mother what it’s like to be that tall.”
The disease is also a learning experience for his children. “I think the thing it has taught my kids is resilience,” he says. “And that’s a great lesson and a great gift I’ve been able to give them just by example.”
Although he first revealed his illness publicly in 1998, he’s been in the public eye more than ever recently, in political ads and TV interviews that showcase the involuntary movements often associated with Parkinson’s.
“I have less control over the way my body moves,” he says. “The thing that gets tougher as you go along is that the medication gets less effective and has more side effects. So it’s a lot more challenging.”
But Boston Legal executive producer Bill D’Elia tells PEOPLE, “Michael has good days and bad, but the debilitating effects of the disease are obvious and ever-present. I’ve seen Michael during the filming appear just as he did in the commercial. We worked with him and around him to create the scenes we needed.”
But Fox and his family do their best to live a normal life, which means “going out to dinner and to movies and traveling and going on vacations,” the actor says. “This time of year what we do is supervise homework and get kids to the bus, music lessons, soccer practice and ballet. Just all the regular stuff.
“There’s nothing like supervising four kids – one in preschool, two in middle school and one in high school. Between talking about colleges and trying to pick a kindergarten, it’s a pretty busy life. It takes your mind off just about everything.”
For Tyler Mills, 19, who, confined to a wheelchair with cerebral palsy, showed up to hear Fox speak in Des Moines, Iowa, the actor – and his message – are inspiring: “We need those kinds of advocates, someone to put a face to this issue. I’ve met Michael. He took the time to talk to me for a half-hour. It was really special.”
It’s that kind of response, says Fox, that makes all the effort worthwhile. “For a lot of people, (getting Parkinson’s) is like being hit by a truck. But in a way it’s also gift – one that keeps on taking, but still a gift. To be able to be of service, to help people, that’s the greatest privilege I could have.”
