The basal ganglia, residing deep below the cerebral cortex, contains a cluster of nerve cells that release dopamine, a neurotransmitter that controls movement. People with Parkinson’s disease have degeneration of these nerve cells and a deficit of dopamine.
This handout provides information about the symptoms, diagnosis, and treatment of Parkinson’s disease, including recommended dietary modifications and other lifestyle changes. Parkinson’s disease affects roughly one of 250 people over 40 and about one of 100 people older than 65, so the chances are pretty high that you know at least one person with the condition. As pointed out in this article by Johns Hopkins, the good news is that people with Parkinson’s disease are living longer and better than ever before.
