Quizplus · Accepted Answer

Parkinson's disease is primarily caused by the loss of dopamine-producing neurons in the substantia nigra region of the brain. This leads to symptoms such as tremors, slowed movement, rigidity, and difficulty with balance and coordination.

This reduction in dopamine is responsible for the movement-related symptoms of Parkinson's disease.
