| Annotation | This study examines whether cognitive markers at prior examinations are indicative of subsequent dementia and mortality. The sample of Swedish subjects aged 84-90 at baseline were re-examined three times over a 6 year period on a comprehensive biobehavioural battery of tests: memory-in-reality (MIR) test; a prose recall test (100 words); the Swedish clock test; the coin test; and the Mini-Mental State Examination (MMSE). Dementia was evaluated at each examination using DSM-III-R criteria. Results indicated that incident cases of dementia had lower cognitive scores both 2 and 4 years prior to diagnosis, compared to non-demented survivors. Evidence for terminal decline was also found, as people who subsequently died also had lower cognitive performance at prior examinations, compared to non-demented survivors. The findings suggest that mild cognitive dysfunction is an important clinical finding among the oldest old, and may herald either the onset of dementia or mortality. |
