Which of the following statements is one of the main differences between Alzheimer’s disease and dementia?

Alzheimer’s disease is a specific disease that can cause dementia, and it can begin before age 65—including in people as young as forty-five. Dementia is a general term for a decline in thinking and memory that interferes with daily life; it is not the cause of Alzheimer’s disease. Therefore, the correct choice is “Alzheimer’s disease can affect individuals as young as forty-five.”
