Parkinson’s illness causes Michael J Fox to stumble on stage during a Back to the Future QA.

Just over a month ago, Michael announced that his almost three-decade battle with Parkinson’s disease, a chronic degenerative condition affecting the neurological system and motor skills, was becoming increasingly difficult.

Michael, most known for playing Marty McFly in all three Back to the Future movies, adopted a laid-back look for the occasion. He wore black jeans, a denim jacket, and a white T-shirt. He finished his casual look with white Nike sneakers, a blue and yellow baseball cap, and clear-rimmed glasses for an air of elegance.
