Question

Quizplus · Accepted Answer

Nigrostriatal neurons, which are responsible for producing dopamine, die in Parkinson's disease. This loss of dopamine leads to the characteristic symptoms of PD, such as tremors, rigidity, and difficulty with movement. PD is not a rare disease, but rather a fairly common neurodegenerative disorder. Most cases of PD are not inherited, although there is a rare genetic form of the disease. Muscle flaccidity is not a typical symptom of PD, as the rigidity associated with the disease actually causes increased muscle tone. While early intervention can help manage PD symptoms, there is currently no cure for the disease.
