Actor Alan Alda, in going public with his Parkinson’s disease, wants to take away the stigma with the disease. He said he is keeping active  by playing tennis, boxing and marching. While there is no known cause and no cure, there are some proven methods of treatment that keep the progressive disease from restricting mobility.  These range from medication to staying fit and deep-brain stimulation.

"Yes, I believe we are near a cure." (5:04) And with early detection and treatment, he said, "There's no reason patients can't get back to an almost completely normal life."
