Question

Quizplus · Accepted Answer

Parkinson's disease is associated with the degeneration of neurons in the substantia nigra, resulting in a decrease in dopamine production and leading to motor symptoms such as tremors, rigidity, and bradykinesia. Amyotrophic lateral sclerosis (ALS), Huntington's disease, and myasthenia gravis are caused by different mechanisms and do not involve the substantia nigra.
