Alan Alda on fighting Parkinson

Is it even possible to choose a favorite Alan Alda character? How about Senator Arnold Vinick on "The West Wing"? Or lawyer Jack Burroughs in "The Four Seasons"? And, of course, "Hawkeye" Pierce, the sarcastic Korean War combat surgeon, on "M*A*S*H"?

"I have doctors coming up to me on the street all the time telling me that seeing me in the show made them want to become a doctor," Alda said. "Not a single one said it made them want to become an actor!"

Long before playing Pierce, Alda – now 90 – was on the other side of the stethoscope. As a seven-year-old he had polio, before there was a vaccine. "My father had just gotten a huge part in a movie, playing George Gershwin," he said. "And about a week after he started shooting, I got polio. And he and my mother had to administer the treatment, which was almost-scalding hot packs of wool on every limb. So, they were practically torturing their kid. I remember thinking it was hard on them."

But Lady Luck dealt the family a difficult hand. His mother, Joan, a former beauty pageant winner, was complicated. "My mother was mentally ill, had schizophrenia and was paranoid," Alda said. "So sometimes the communication would be about the crack in the wall was where they had a camera taking pictures of us. I think that contributed a lot to tools I later had, trying to figure out what's real and what's not real. I had to pick one reality and try to stick with that. … It made me more observant. And I think it even helped – I'm just realizing this for the first time in this moment! – I think

Which had a huge impact on viewers. More than 100 million people watched the series' final episode. "They think 106. But I think it was probably more. Not that I'm greedy!" he laughed.

He said, "Improvisation really puts you in touch with the other person, and that's when I realized the value of connection."

To Alda, connecting with people means being clear and honest, which is why he will openly discuss his Parkinson's disease. "I had a symptom, which at the time was not that well-known: Acting out your dreams," he said. "I had a dream that somebody was attacking me. And I picked up a sack of potatoes and threw it at 'em. What I was really doing was throwing a pillow at Arlene, my wife."

At the time he had no other symptoms: "I had no twitch, no tremor, no problems with my voice."

There's currently no cure for the neurological disorder, but there are medications and other treatments. "I don't let Parkinson's define me," he said. "It's not who I am. It's just a hobby."

But what is funny about Parkinson's? "I'll be at the computer keyboard writing an email, and Dr. Parkinson is moving my hand all over the screen. I have the mouse, and he's eliminating things and he's deleting things that I need," Alda laughed. "Once in a while I get frustrated. But I find what makes me laugh about it, and then I go tell Arlene. Laughing first brought us together. We were invited to dinner at a friend's house. And Arlene was sitting at one end of the table, and I was sitting at the other end. And I noticed that she was laughing at my jokes. So already I was smitten. In March,

Alan Alda says he feels really good, even if Arlene has to help button his shirt in the morning, which he admitted he hated. "Of course, I feel that from time to time," Alda said. "I do hate it, but the only thing that's helpful is: what haven't I tried? And pretty soon, you get the feeling, 'If I keep looking for new ways to try this, I'll get a solution.' It's a puzzle. Will I be able eventually to put my socks on? The last time I put my socks on was a tremendous moment to celebrate!"
