Michael J. Fox has lived publicly with Parkinson’s disease for more than three decades. Diagnosed in 1991 at age 29, while already one of Hollywood’s biggest young stars, he kept the diagnosis private until 1998. He later became one of the world’s most prominent advocates for Parkinson’s research while continuing to act for many years. In 2026, his appearance in the third season of Apple TV+’s Shrinking gave longtime fans another chance to see him on screen.
The diagnosis came during the height of his success with Family Ties and the Back to the Future films, bringing an unpredictable challenge to both his career and personal life. Although he continued acting, Parkinson’s gradually made performing more difficult, and Fox has openly discussed the long process of accepting the condition.
Fox has never pretended the disease is easy. He has described Parkinson’s as difficult and frustrating while refusing to let it define his life as a tragedy. In interviews around Still: A Michael J. Fox Movie, he spoke about rejecting pity and focusing on what can still be achieved—a mix of realism and determination that has shaped his public journey.
