Question: 237
7. Symptoms of Alzheimer's disease include all of the following EXCEPT:
- A. disorientation.
- B. forgetfulness.
- C. mood swings.
- D. slow, uncoordinated fine movements.
Correct Answer: D
Explanation:
Alzheimer's disease involves the loss of vital neurons throughout the cerebral cortex; symptoms include disorientation (choice A can be eliminated), forgetfulness (choice B can be eliminated), mood swings (choice C can be eliminated), and impairment of other cognitive functions like speaking, writing, thinking, reasoning, and making judgments and decisions. As the disease progresses, it can also lead to changes in personality and behavior, depression, and social withdrawal. However, Alzheimer's disease does not affect the ability to produce fine movement (choice D is correct).
