Alzheimer's disease accounts for 50–60% of dementia cases in older people. Dementia with Lewy bodies is now recognized as the second most common type of dementia. It is different from Alzheimer's disease and has important pharmacotherapeutic implications. Key features include early‐onset, persistent, well‐formed, visual hallucinations and motor features of parkinsonism. Pharmacologic management of neurobehavioral symptoms is complicated by an exaggerated response to neuroleptics, which causes excessive morbidity and mortality. Patients with dementia with Lewy bodies may be particularly responsive to cholinesterase inhibitors. When neurobehavioral symptoms are severe enough to require pharmacologic intervention, it is recommended that agents such as trazodone or cholinesterase inhibitors be considered first‐line therapy. If these fail, neuroleptics may be prescribed with caution.
