title: Personality and dementia.
abstract: Personality describes persistent human behavioral responses to broad classes of environmental stimuli. Change in personality may be an early sign of dementia. Our goal was to review scientific literature on the association between personality and dementia. Medline and Google Scholar searches were conducted for relevant articles, chapters, and books published since 1980. Search terms used included personality, dementia, Alzheimer's disease, frontotemporal dementia, dementia with Lewy bodies. People with dementia commonly exhibit changes in personality that sometimes precede the other early clinical manifestations of the condition, such as cognitive impairment. Premorbid personality might be a determining factor so that caricature or exaggeration of original personality emerges as dementia progresses. Although it is generally accepted that these personality changes reflect the impact of progressive brain damage, there are several possible patterns of personality alterations with dementia. Early identification of personality modifications might assist with the timely diagnosis of dementia.
