Question

Quizplus · Accepted Answer

Dopamine does not readily penetrate the blood-brain barrier, making it ineffective in treating Parkinson's disease, which primarily affects the brain. While dopaminergic neurons are important in Parkinson's disease, their restriction to the peripheral nervous system is not the reason why dopamine is ineffective as a treatment option. Parkinson's disease is also not primarily a cholinergic or noradrenergic dysfunction, although changes in these neurotransmitter systems may contribute to some of the symptoms of the disease. d'Orta is not a recognized treatment for Parkinson's disease.
