Exercise and Parkinson's

"Parkinson's disease is a disease of motor and other brain function, and it is a component of Lewy Bodies Dementia.  Generalized slowness of movement occurs in nearly all people who have Parkinson -- or in the case of Lewy Bodies Dementia, parkinsonian features.  Some people also have tremors, rigidity and balance problems.  Any exercise that helps with balance, flexibility and strength is helpful for someone with Parkinson's.  It is particularly helpful to have exercise supervised or designed by a physical therapist.  Tai chi is especially helpful for balance in persons with Parkinson's.
