An 80-year-old male with mild Alzheimer’s disease has been started on donepezil 5 mg after he continued to have difficulty in financial matters and keeping track of the day of the week and time. After 3 months the family feels that there has been no improvement. There are no complaints of nausea, dizziness, or hypotension. The patient’s wife feels the medication is unnecessary. The best advice is:
a. Discontinue donepezil
b. Increase the donepezil dose to 10 mg
c. Continue donepezil to prevent further plaque formation
d. Continue donepezil for 3 to 6 months and reevaluate mental status
e. Begin a new anticholinesterase inhibitor
