Cholinesterase inhibitors. Comparing the options for mild-to-moderate dementia

Cholinesterase inhibitors can be used as one element of a comprehensive approach to management of mild-to-moderate AD. Benefits include modest cognitive improvement, increased activation, and improved mood and behavior. Patients with other disorders, such as Lewy-body dementia, may also improve. The most common side effects include GI disturbances, insomnia, dizziness, fatigue, and muscle cramps. Adverse effects can be significantly reduced by waiting 4 to 6 weeks before increasing doses. Insomnia may be alleviated by having the patient take the medication early in the day.
