Michael J. Fox was 29 years old when he was diagnosed with Parkinson’s disease.

Quick Scoop

Here’s a bit more context around your question how old was Michael J Fox when he got Parkinson's:

  • He first noticed symptoms (a twitch in his pinky finger) while filming the movie Doc Hollywood in 1991.
  • That same year, at age 29, he received a diagnosis of early-onset/young-onset Parkinson’s disease.
  • He kept the diagnosis private for several years before going public and later founded The Michael J. Fox Foundation in 2000 to support Parkinson’s research.

A tiny “story” angle

In 1991, at just 29, at the height of his fame after Back to the Future and Family Ties , Fox noticed something small but persistent: his pinky finger wouldn’t stop twitching.

What seemed like a minor annoyance turned into a life-changing diagnosis of young-onset Parkinson’s, a condition usually seen in much older adults, and it eventually pushed him to become one of the most visible advocates for Parkinson’s research in the world.

TL;DR: Michael J. Fox was 29 years old when he was diagnosed with Parkinson’s disease.
