Provocative international disparities reported in the prevalence rates of dementia and depression require further investigation.
This is the first psychiatric study, to the best of our knowledge, about the prevalence of DSM-III-R dementing and depressive disorders and their relationships in a representative, stratified community sample of the elderly in both a Spanish-speaking country and southern Europe.
A two-stage screening was completed in 1080 elderly.
Sampling with replacement was done, and the cumulative response rate was 88%. In phase 1, lay interviewers administered the Spanish versions of the Mini-Mental State examination and the Geriatric Mental State Schedule-Automated Geriatric Examination for Computer Assisted Taxonomy package.
In phase 2, research psychiatrists administered the same instruments and the History and Aetiology Schedule to all the probable cases and a similar number of randomly selected, probably normal subjects.
An estimated 5.5% of the elderly were considered to have a dementing disorder, the most prevalent type being primary degenerative dementia, Alzheimer's type (4.3%), and multi-infarct dementia (0.6%). Conslusions : Among the elderly, the prevalence of Alzheimer's disease and multi-infarct dementia, as opposed to depression, increases steeplywith age.
The overlap found between dementia and depression may have nosological implications.
