Which disease is described as progressive, with unknown cause and no cure?

• A. Spina bifida
• B. Subarachnoid hemorrhage
• C. Tourette syndrome
• D. Parkinson's Disease

Answer: (D)

This item is asking you to pick a condition that is progressive, has an unknown cause, and currently has no cure. The match is Parkinson's disease. It’s a chronic neurodegenerative disorder in which dopamine-producing neurons in the brain progressively die, leading to worsening motor symptoms such as tremor, slowed movements, stiffness, and balance problems over many years. The exact cause isn’t fully understood, involving a mix of genetic and environmental factors, and while there are effective treatments to manage symptoms and improve function, there is no cure to halt or reverse the disease. The other conditions don’t fit as well. Spina bifida is a congenital neural tube defect present at birth, not something that progresses in the same degenerative sense. Subarachnoid hemorrhage is an acute, life-threatening bleed that requires emergency treatment, not a slowly progressive condition. Tourette syndrome is a neurodevelopmental disorder characterized by tics; while its causes aren’t completely known and there’s no cure, it isn’t described as progressively worsening over time in the same way Parkinson’s is.
