Parkinson's disease is a nervous system disorder that affects the brain. This disease involves the part of the brain that controls extremity movement and the muscles that generate speech. The main symptoms include tremors, muscle rigidity and difficulty with coordination, balance, walking, and changes in speech.
Although there is no cure for Parkinson's disease, various treatments can relieve symptoms and help patients maintain their quality of life. Physical, occupational, and speech therapy are forms of treatment known to help individuals with Parkinson's disease.
