Michael J. Fox's Personal Battle
In 1991, at the height of his career, Michael's life took an unexpected turn. He was diagnosed with Parkinson's disease, a chronic neurological disorder that can cause debilitating tremors.
At first, Michael kept his diagnosis private. He went on to produce and star in the comedic series Spin City . Then, as his symptoms worsened and became harder to disguise, Michael went public with his battle.
