A cure for Alzheimer's disease (AD) is still far off, and clinicians face the burden of caring for patients at all stages of dementia for the foreseeable future. Those with advanced disease suffer neurological symptoms and signs that include incontinence; problems with gait and mobility; marked cognitive, language, and functional impairment; and in about 90% of patients, significant behavior problems. Dementia precludes the ability to initiate meaningful activities or social interactions. Whether patients are resident in the community or living in a nursing home, this composite reflects a highly complex medical and neuropsychiatric management challenge. Predictable medical conditions also must be addressed (i.e., those that accompany dementia, such as parkinsonism, and those that are prevalent in any aging population, such as hypertension). Clinicians can better address these problems with awareness of current treatment options. Placebo-controlled trials of some psychotropic agents have shown modest favorable effects on behavior problems. Use of acetylcholinesterase inhibitors (AChEIs) to treat cognitive impairment and secondary behavioral symptoms derives primarily from results of placebo-controlled clinical trials. Trials in patients with moderate to severe AD, outpatients as well as nursing home residents, show overall effects similar to those seen in outpatients with milder dementia. Treatment with AChEIs may delay institutional placement. Memantine has shown benefit in trials in moderate to severe dementia, although it is not yet approved in the United States. Emerging data have expanded physicians' ability to use pharmacotherapy in patients with advanced dementia. Physicians need to enact the principle that something can be done for our afflicted parents and grandparents.
