What is Parkinson’s disease?
According to the Parkinson’s Foundation, Parkinson’s disease is a progressive, neurological disorder that occurs when the cells in the brain that make dopamine start to die. Symptoms start gradually, sometimes starting with a barely noticeable tremor in just one hand. Tremors are common, but the disorder also commonly causes stiffness or slowing of movement.
In the early stages of Parkinson’s disease, the face may show little or no expression. Your arms may not swing when you walk. Your speech may become soft or slurred. Parkinson’s disease symptoms worsen as your condition progresses over time.
