Which disease is characterized by tremors and a stooped posture, often with a pin rolling movement?

• A. Alzheimer's
• B. Huntington's
• C. Multiple sclerosis
• D. Parkinson's

Answer: (D)

Parkinson's disease presents with a resting tremor that is often described as a pill-rolling movement, along with a stiff, stooped posture and slowed movements. This combination arises from loss of dopamine-producing cells in the brain, leading to motor symptoms like tremor at rest, rigidity, and bradykinesia that contribute to the characteristic hunched, shuffling gait. The tremor described as pill-rolling is a classic sign and helps distinguish this condition from others. By contrast, Alzheimer’s disease mainly involves memory and cognitive decline; Huntington’s disease features choreiform, jerky movements and behavioral changes; multiple sclerosis presents with episodes of weakness, numbness, vision problems, and coordination issues due to demyelination. So the described symptoms most closely fit Parkinson's disease.
