Alzheimer's Disease is defined as progressive, degenerative disease that occurs in the brain.

• A. Inflammation of the meninges
• B. Degenerative muscle disease
• C. Progressive, degenerative disease that occurs in the brain
• D. Acute infection of the brain

Answer: (C)

Alzheimer's Disease is a progressive neurodegenerative condition that affects the brain, leading to a gradual decline in memory and thinking skills. The best choice matches this definition exactly by describing a progressive degenerative disease that occurs in the brain. The other options describe different conditions: inflammation of the meninges would be meningitis, an inflammation of brain coverings; a degenerative muscle disease refers to disorders primarily affecting muscle tissue; an acute infection of the brain points to conditions like encephalitis. Understanding that Alzheimer's is a slowly advancing brain disease helps distinguish it from inflammatory, infectious, or muscle-related conditions.
