Parkinson's Disease commonly includes tremors, a shuffled gait, and mask-like expression; many patients may develop what associated condition?

• A. Dementia
• B. Osteoarthritis
• C. Incontinence
• D. Nosocomial infection

Answer: (A)

Parkinson's disease not only affects movement but also cognitive function as it progresses. The brain changes involved, including Lewy bodies in cortical areas, can lead to dementia, with difficulties in memory, attention, and judgment that develop later in the disease. This makes dementia the most commonly associated condition seen in many Parkinson's patients. While conditions like osteoarthritis, incontinence, or hospital-acquired infections can occur in older adults, they are not specific associations of Parkinson's disease itself.
