What are the most common treatments for Parkinson's disease?

The common feature among these disorders is that the parts of the brain that are affected are part of the same system. The group of structures often entangled in these abnormalities includes the basal ganglia (a large cluster of cells that lie deep in the hemispheres of the brain). The anatomic and biochemical connections from the basal ganglia to other parts of the brain are extremely complex, and not fully understood. Although the actual weakness can develop in some pathological states involving the basal ganglia, most of these diseases affect an individual’s speed, quality and ease of movement.
