Alda reveals Parkinson’s battle

Legendary actor Alan Alda has been battling Parkinson’s disease for more than three years, he revealed Tuesday on “CBS This Morning.”

The “M*A*S*H” star, 82, says he went to his doctor after he began to experience a very early symptom of the disease, and he’s maintained a positive mindset about his condition in the years since.

“The reason I want to talk about it in public is that I was diagnosed 3½ years ago, and I’ve had a full life since then,” Alda said on the talk show.

The actor said he wanted to open up about his experience because he’s been doing TV interviews recently and had noticed his thumb twitching in certain shots.
