Actor Michael J. Fox was diagnosed with early-onset Parkinson's disease in 1991 at the age of 29. Despite initially hiding his illness for seven years, Fox shared his diagnosis publicly in 1998 and founded his foundation, the Michael J.-Fox Foundation for Parkinson's Research, two years later. Since 2000, Fox has raised over $2 billion and made significant strides in researching the progressive neurodegenerative disorder. He incorporated his diagnosis into his future acting roles to promote research. Fox has been open about his struggles with Parkinson's but continues to see the positive in his life.
