Which statement about Alzheimer's disease is true?

• A. It is a temporary memory issue that improves spontaneously.
• B. It is only a childhood developmental disorder.
• C. It is a degenerative brain disease and the most common form of dementia.
• D. It is a muscular disorder affecting mobility primarily.

Answer: (C)

Alzheimer's disease is a progressive neurodegenerative condition that causes a gradual decline in memory, thinking, and daily functioning. It is the most common form of dementia, meaning it accounts for the majority of dementia cases seen in older adults. This is not a temporary memory issue that improves on its own, nor is it something that begins in childhood. It’s also not a muscular disorder; the main problems arise from brain cell loss and changes in brain structure and chemistry as the disease progresses. Pathologically, this includes neuron damage and brain changes like amyloid plaques and tau tangles, which underlie the gradual cognitive decline.
