| Annotation | The accuracy of a dementia diagnosis by specialist physicians, as verified by autopsy, is greater than 90% in many series. This Canadian study investigated whether clinical features of dementia could be detected, retrospectively, using brains donated by individuals who did not have expert dementia diagnoses before death. Informants for 36 individuals who had donated their brains were interviewed by specialist physicians using a semi-structured retrospective interview based on the Brief Cognitive Rating Scale (BCRS). The mean duration of dementia was between 8.5 and 12. 8 years based on proxy reports, and most cases suggested severe dementia on the retrospective BCRS (RetroBCRS) before death. A score of 4 or more on the RetroBCRS had 100% sensitivity and specificity in detecting dementia. The accuracy of the retrospective diagnosis of the cause of dementia, compared with autopsy, was 92%. The study concluded that the RetroBCRS used by an expert physician with a reliable informant is a valid method of detecting dementia and determining whether Alzheimer's diseasee (AD) was present.
