Which condition causes tremors, a shuffled gait, and mask-like expression, with many developing some level of dementia?

• A. Incontinent
• B. Osteoarthritis
• C. Nosocomial
• D. Parkinson's Disease

Answer: (D)

These signs point to Parkinson's disease, a neurodegenerative movement disorder. The resting tremor, the small, shuffling steps of the gait, and the mask-like, expressionless face (hypomimia) come from reduced movement and stiffness caused by loss of dopamine-producing cells in the brain. Over time, Parkinson's can include cognitive changes, and many people develop some level of dementia as the disease progresses. The other options don’t fit this pattern: urinary incontinence is a urinary issue, osteoarthritis causes joint pain and stiffness but not a resting tremor or masked face, and nosocomial refers to hospital-acquired infections.
