Question

Quizplus · Accepted Answer

Parkinson's disease is caused by the degeneration of dopamine neurons in the substantia nigra, an area of the brain responsible for movement control. The loss of dopamine leads to the motor symptoms associated with Parkinson's disease. Destruction of the caudate and putamen, decreased availability of serotonin, and atrophy of the motor cortex are not directly linked to Parkinson's disease.
