Which statement correctly describes Alzheimer's disease?

• A. A reversible mood disorder.
• B. A progressive neurodegenerative disease causing cognitive decline and functional impairment.
• C. A kidney disorder.
• D. An acute infectious disease.

Answer: (B)

Alzheimer's disease is a progressive neurodegenerative disorder characterized by worsening memory and thinking abilities, eventually leading to impairment in daily functioning. This captures the essential idea that brain cells progressively die, especially in memory and reasoning regions, causing symptoms to steadily worsen over time and currently not being fully reversible. It is not a mood problem, not a kidney issue, and not an acute infectious disease, which is why describing it as a progressive neurodegenerative condition with cognitive decline and functional impairment best fits.
