Depression, dementia, and social supports

Recent literature on the relationships among dementia, depression, and social support was reviewed, with particular emphasis on the diagnostic differentiation of dementia and depression, and the role of these three entities in elderly individuals with cognitive impairment. Dementia-like symptoms arising in depression and the coexistence of dementia and depression are discussed. Research is necessary to determine more objective criteria for depression and dementia, to provide cognitive and psychiatric testing for elderly individuals, to clarify the diagnostic or prognostic value of the term pseudodementia, and to further elucidate relationships between depression, dementia, and social support.
