It's sad to see Ali going through such a thing as Parkinson's.
My step-grandfather went through that torture, and a long-term friend/business associate of mine is going through the late stages now. There's not a lot that they can do, the few medications they have, tend to not work for the long term as the body becomes immune to them. In the late stages there are a few brain surgeries that can be done, but they are experimental and outlawed in the U.S. The research in the states is not progressing due to the religous right and they're continued stance angainst stem-cell use and limitations.
As the years go by the physical body basically slips into a coma, unable to physically control and function, while the mind and mental being is still there but unable to react.
