Muhammad Ali is Diagnosed with Parkinson's Disease

In November of 1982, Ali returned to the gym to train for a three-week exhibition tour, with stops planned in Saudi Arabia, India, and Pakistan. However, since retiring, Ali's health, as well as the health of his former boxing assistants, had intensely deteriorated. In 1984, after checking himself into Columbia Presbyterian Hospital, Ali was given a devastating diagnosis: Parkinson's disease.
