Question

Quizplus · Accepted Answer

Parkinson's disease is caused by the progressive degeneration of dopaminergic neurons in an area of the brain called the substantia nigra. These neurons are responsible for producing dopamine, a neurotransmitter that helps regulate movement and coordination in the body. As dopamine levels decrease, the characteristic motor symptoms of Parkinson's disease, such as tremors, rigidity, and bradykinesia (slowness of movement), become more pronounced.
