| Annotation | Dementia in community settings is often diagnosed by computerised algorithms. This study examines the extent to which independent diagnosticians agreed among themselves in diagnosing dementia, severity and type when presented with data obtained during a population-based incidence study of cognitive decline and dementia. It also examines how judgements, based initially on respondents' self-reports and cognitive performance, were affected first by informants' reports and then by short case-vignettes written by trained lay interviewers. Diagnosticians' diagnosis of dementia is then compared with the algorithmic diagnosis (AGECAT). Items presented were from two screening interviews at wave 1 and wave 2, separated by 2 years, and from wave 2 assessment and informant interviews, and included medical, psychiatric and ADL (activities of daily living) items and interviewers own observations. The sample of 42 derived from the first year of the wave 2 assessments. Agreement on diagnosis and type of dementia improved with increasing information, particularly from informants, but remained poor regarding severity. Operational and algorithmic diagnoses showed good agreement. Causes of disagreement and relevance of the results are discussed. (RH. |
