What is the goal of drug therapy in treating Parkinson's disease?

• A. Cure the disease
• B. Prevent onset
• C. Slow the progression of the disease
• D. Completely reverse symptoms

Answer: (C)

Parkinson’s disease is a progressive neurodegenerative condition where dopamine-producing neurons are lost over time. Drug therapy aims to restore dopaminergic signaling enough to reduce motor symptoms and help people stay independent, but it cannot cure the disease or completely reverse the damage that has already occurred. There isn’t a proven way to prevent the onset of Parkinson’s once the process has started. The level best achieved with medications is to slow the decline in function and improve quality of life as the disease progresses. Some treatments may be explored for potential disease-modifying effects, but they do not change the reality that the underlying neurodegeneration continues.
