Abstract

Behavioral and psychological symptoms of dementia, including depression, might complicate the course of the disorder additionally. Dementia is more frequent in older people and suicide rates are higher in later life than in any other age group. To explore the phenomenology of suicidal behavior in patients with dementia, we searched electronic databases and key journals for original research and review articles on suicide in demented patients using the search terms "suicide, suicidal behavior, dementia, Alzheimer disease, and old age". Although cognitive impairment could result in a diminishing ability to think flexibly and to solve problems or to cope with conflict, in the early stage of dementia such impairments are absent or mild, and suicidal behavior might be expected, especially following diagnosis. In addition, personality changes based on declining cognitive capacity and the neurochemical imbalances described in late-life depression and in dementia may predispose patients to aggressive or impulsive acts, such as suicide attempt. The literature on suicidal behavior and dementia highlights the need for further research in this area.
