Michael J. Fox, the beloved Back to the Future star, has been a public advocate for Parkinson’s disease awareness for over two decades. Recently, he has opened up about the increasing challenges he faces as the condition continues to impact his health, including the effects on his short-term memory and other aspects of daily life.
Fox’s journey with Parkinson’s is not just a personal battle—it has become a beacon of hope and resilience for millions around the world.
Diagnosed at 29: A Life Changed by Parkinson’s Disease
Michael J. Fox was diagnosed with Parkinson’s disease in 1991 at the young age of 29, a condition he made public seven years later in 1998【source: Michael J. Fox Foundation】. Parkinson’s disease is a progressive neurodegenerative disorder that primarily affects movement but can also impair other cognitive and sensory functions【source: Mayo Clinic】.
Despite the diagnosis, Fox initially continued acting, even starring in the successful sitcom Spin City, for which he won multiple awards. However, by 2000, the worsening symptoms led him to semi-retire from full-time acting to focus on his health and advocacy work.

Impact on Memory and Acting Career
In a candid interview with People magazine, Michael J. Fox shared that his short-term memory has been significantly impacted【source: People Magazine】.
“My short-term memory is shot,” he revealed, explaining that remembering lines for acting roles has become increasingly difficult. “I used to have a real proficiency for lines and memorization, but the last couple of years have been trickier than most.”
Although he continued to work in various acting projects, including voice roles in animated films such as Stuart Little and Atlantis: The Lost Empire, he admitted that heavily worded scripts have become more challenging. Fox’s honesty about these struggles reflects the broader reality faced by many Parkinson’s patients, where cognitive and motor skills can decline over time.

Loss of Sense of Smell: A Lesser-Known Symptom
In a recent conversation with comedian Mike Birbiglia, Fox also shared that he has lost his sense of smell, a symptom that is surprisingly common among Parkinson’s patients【source: Parkinson’s Foundation】.
Although losing this sense saddened him, he expressed that he still retains vivid memories of certain smells, like the scent of pine during Christmas. According to medical research, anosmia (loss of smell) can occur months or even years before more recognizable motor symptoms of Parkinson’s disease appear【source: Mayo Clinic】.
This symptom often goes unnoticed but can be an important early indicator of the disease’s onset.

Family Support and Personal Resilience
Despite his health challenges, Michael J. Fox remains optimistic, largely due to the unwavering support of his family. He has been married to actress Tracy Pollan since 1988, and the couple has four children【source: Biography.com】.
Fox often speaks about how his family’s love and encouragement provide him with strength. In interviews, he emphasizes that surrounding himself with positivity has been crucial in coping with the progression of his illness.
“People don’t believe me, but I love life. I love being with my family,” he told People magazine. His optimism remains a defining characteristic, even as he faces increasing physical limitations.
