Quizplus · Accepted Answer

Parkinsonism is primarily associated with the degeneration of neurons that use dopamine as a neurotransmitter in the substantia nigra, a region of the brain. This degeneration leads to the characteristic symptoms of tremors, muscular rigidity, and reduced control over voluntary movements.
