Depression in dementia.

People with dementia of any type have a high incidence of major depression. The occurrence of a first major depressive episode in an older adult is a risk factor for developing dementia. Management of depression in a person with dementia should be enthusiastic with an aim to optimise quality of life. Non-pharmacological and pharmacological strategies are both important in treating depression in dementia and management of these patients requires a collaborative approach. Selective serotonin reuptake inhibitors are the first-line pharmacotherapy for depression in dementia, although they are less likely to be effective in older people.
