The cholinesterase inhibitors provide the first clearly effective treatments for the cognitive deficits of AD and appear to have a beneficial effect on activities of daily living function and noncognitive behavior. There is increasing support for starting donepezil, rivastigmine, or galantamine early in the disease course and maintaining treatment at least during the early and middle stages of AD. Depressive signs and symptoms complicating AD are treated best with SSRIs. Placebo-controlled trials support the use of citalopram and sertraline in AD complicated by depression. The atypical antipsychotics are the first choice for managing psychosis and disruptive agitation in AD and particularly in the Lewy body variant of AD. Studies suggest that low-dose treatment with risperidone, 1 mg/d, or olanzapine, 5 mg/d, offers the optimal ratio of therapeutic to adverse effects.
