Фрагмент работы

The factual cause of Parkinson's is unknown. Parkinson's Disease is a a progressive disorder characterized primarily by uncontrollable tremors in the limbs, a shuffling gait, and generalized muscular rigidity. It is usually not fatal, but leads to changes in the entire body. Parkinson's is also know as PD. Recently a defective gene found in few families with backrounds of PD was found. Though researchers do not believe that genetic
conditions are responsible for the disease. They instead think that it could be the combination of a genetic preference and an unidentified environmental stimulate. When PD occurs, degenerative changes are found in an area of the brain, which produces dopamine. Parkinson's is characterized by a severe shortage of dopamine.
