Question

Quizplus · Accepted Answer

Parkinson's disease is a neurological disorder that occurs due to degeneration of dopamine-releasing neurons in the substantia nigra. This results in a lack of dopamine, a neurotransmitter responsible for motor movements, leading to symptoms such as tremors, rigidity, and bradykinesia. Alzheimer's disease is a neurodegenerative disorder that primarily affects cognitive function, while Huntington's disease is an inherited disorder that leads to the progressive breakdown of brain cells. Autoimmune diseases result from the body's immune system attacking its own tissues and organs, and are not related to Parkinson's disease.
