Which of the following would most likely be an initial treatment for a patient with Alzheimer's disease?
1. Levodopa (Larodopa)
2. Haloperidol (Haldol)
3. Benztropine mesylate (Cogentin)
4. Donepezil hydrochloride (Aricept)
Correct Answer: 4
Rationale: Donepezil hydrochloride (Aricept) is an acetylcholinesterase inhibitor, and the most frequently used drug for Alzheimer's disease. Levodopa (Larodopa) and benztropine mesylate (Cogentin) are used for Parkinson's disease. Haloperidol (Haldol) can be used in some cases of Alzheimer's disease, but due to its adverse effects is not frequently used.
