Background The aim of this study was to investigate the causes,severity, and prevalence of dementia in a representative sampleof 494 85-year-olds living in Gothenburg, Sweden.
Methods The study included a psychiatric interview, neuropsychologicaland physical examinations, comprehensive laboratory tests, electrocardiography,chest radiography, computed tomography (CT) of the head, andanalysis of cerebrospinal fluid. A person close to each subjectwas also interviewed. Dementia was defined according to thecriteria proposed in the Diagnostic and Statistical Manual ofMental Disorders (third edition, revised), Alzheimer's diseaseaccording to the criteria of the National Institute of Neurologicaland Communicative Disorders and Stroke and the Alzheimer's Diseaseand Related Disorders Association, and vascular dementia accordingto recently proposed criteria that incorporate information fromCT scanning and the patient's neurologic history.
Results The prevalence of dementia was 29.8 percent (147 subjects).The condition was mild in 8.3 percent, moderate in 10.3 percent,and severe in 11.1 percent. There were no significant sex-relateddifferences in prevalence or severity. Of the subjects withdementia, 43.5 percent had Alzheimer's disease, 46.9 percenthad vascular dementia (multi-infarct dementia in 34.6 percent,dementia related to cerebral hypoperfusion in 4.1 percent, andmixed dementia in 8.2 percent), and 9.5 percent had dementiadue to other causes. The three-year mortality rate was 23.1percent in the subjects without dementia, 42.2 percent in thepatients with Alzheimer's disease, and 66.7 percent in the patientswith vascular dementia. Infarcts detected by CT scanning weresignificantly more common in the subjects with dementia thanin those without it (27.9 percent vs. 12.6 percent).
Conclusions Dementia was present in nearly a third of unselected85-year-olds in Sweden. Almost half these subjects appearedto have vascular dementia, which may currently be more amenableto prevention or treatment than Alzheimer's disease.
