title: [Dementia diseases and minor cognitive impairments in elderly patients in general practice. Results of a cross-sectional study].
abstract: General practitioners in 24 Mannheim practices kept a record of all over-65-year-old patients seen during four weeks (n = 3,737), and made ratings of their cognitive functioning with the help of simple guidelines. For a sub-sample of patients (n = 407), these ratings could be compared with assessments made by the research team, on the basis of a standardized interview and test procedure (Hierarchic Dementia Scale). The research data indicate that 8% of the patients manifested clinical dementia, a further 8% so-called 'mild dementia' and 17% milder, non-disabling degrees of cognitive impairment. The proportion of affected persons in each of the groups rises steeply with increasing age above 65 yr. The ability of the practitioners to detect dementia--including the milder degrees--among their elderly patients exceeded expectation (sensitivity 92%; specificity 76%). The test-score profiles of the patients, grouped according to their own doctors' ratings, conformed to clinical concepts of the progressive course ('staging') of dementing illness, while the degree of disability in everyday life, and dependency on others, also increased steeply across the groups. These findings emphasize the importance of general medical practice for the early detection of dementia in the elderly population, and potentially also for case management.
