NEW YORK — Michael J. Fox’s battle with Parkinson’s disease has “gotten harder,” but he remains optimistic that a cure is coming.

The 65-year-old television star was 29 years old when he was diagnosed with the the incurable neurological disorder in 1991. He went public with his condition in 1998 and retired from acting for for the first time in 2000 when he started the Michael J. Fox Foundation for Parkinson’s Research.

Following a second retirement due to his deteriorating health in 2020, Fox is very much back on the scene. The Canadian star was nominated for a 2026 Emmy Award for his work on Apple TV’s “Shrinking.” But life isn’t getting easier as he continues his fight.

“Of course, things have gotten harder over the years,” he admitted to People in an interview published Wednesday. “I’m privileged to commit my time and energy to bringing everything I’ve got to help cure this disease.”

He was honored with the Lasker-Bloomberg Public Service Award for Transformative Leadership in Parkinson’s Research on Wednesday in recognition for his foundation’s work. Fox’s team has raised $3 billion in search of a cure, which the “Back to the Future” star believes is on the way.

“We don’t know exactly when it’ll happen, but it will happen,” Fox told People.

The five-time Emmy winner was one of the biggest stars on primetime while playing Alex P. Keaton in the NBC sitcom “Family Ties” from 1982 to 1989. He also enjoyed great success with the show’s “Spin City” and “The Good Wife.”

His biggest role on the movie screen was arguably Marty McFly in the “Back to the Future” trilogy. He also starred in the teen comedy “Teen Wolf” and the debauched New York-centric film “Bright Lights, Big City.”
