Which statement about Parkinson's disease medications is true?

• A. They slow progression but do not cure
• B. They cure the disease
• C. They reverse brain damage
• D. They prevent onset

Answer: (A)

Parkinson's drugs are symptom-focused treatments that boost or mimic dopamine to compensate for loss of dopaminergic neurons. They improve motor symptoms such as tremor, stiffness, and slowness, and can help people stay functional for longer. However, they do not stop the underlying neurodegenerative process nor repair already damaged brain tissue. They do not prevent the disease from starting, nor do they cure it or reverse brain damage. So the true statement is that these medications slow functional decline while not offering a cure.
