A handout on Alzheimer's disease states, "Alzheimer's is the third leading cause of dementia in older persons. It only affects the elderly, it causes marked deterioration in mental functioning without emotional disturbances, and it has no cure." Which portion of this statement is accurate

This question is missing the options. I've found the complete question online. It is as follows:

A handout on Alzheimer's disease states, "Alzheimer's is the third leading cause of dementia in older persons. It only affects the elderly, it causes marked deterioration in mental functioning without emotional disturbances, and it has no cure." Which portion of this statement is accurate:

a) It is accurate to say that Alzheimer's only affects the elderly.

b) It is accurate to say that Alzheimer's has no cure.

c) It is accurate to say that Alzheimer's is the third leading cause of dementia in older persons.

d) It is accurate to say that Alzheimer's causes marked deterioration in mental functioning without emotional disturbances.

Answer:

The portion that is accurate is letter b) It is accurate to say that Alzheimer's has no cure.

Explanation:

So far, Alzheimer's disease is still incurable, which makes letter b correct. However, it is not exclusively a disease of the elderly. Early-onset Alzheimer's affects younger people, which makes letter a incorrect. Letter c is also wrong, since Alzheimer's is the first, not the third, cause of dementia. Finally, letter d is incorrect for affirming that there are no emotional disturbances resulting from the disease.
