The prevalence of dementia: A quantitative integration of the literature

Jorm, A. F., Korten, A. E., Henderson, A. S.·1987·Acta Psychiatrica Scandinavica

Abstract

ABSTRACT— Data from studies of dementia prevalence between 1945 to 1985 were analyzed statistically. Prevalence rates were found to vary as a function of methodological differences between studies. However, despite these differences, the relationship between prevalence and age was found to be consistent across studies, with rates doubling every 5.1 years. Across studies, Alzheimer's disease (AD) was found to be more common in women, with a tendency for multi‐infarct dementia (MID) to be more common in men. There were also national differences in the relative prevalence of AD and MID, with MID being more commmon in Japanese and Russian studies, no difference in Finnish and American studies, and an excess of AD in other Western European countries.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
