| Annotation | Factors related to physical health have been implicated in both normal and pathological ageing of cognitive abilities. To substantiate this notion, the authors studied existing morbidity, as diagnosed by the general practitioner according to well-defined criteria, as a potential predictor of cognitive test performance. A sample of 1,360 people aged 24 to 81 and living in the community was stratified by age, sex, and general ability. Active and total morbidity were classified according to the International Classification of Primary Care. Neurocognitive tests were used to assess domains of verbal memory, sensorimotor speed and cognitive flexibility. Multiple regression analyses adjusted for age, sex and educational level showed both insulin-dependent and non-insulin-dependent diabetes to be negatively associated with all cognitive measures. More specific negative associations were found for chronic bronchitis (performance speed) and presbyacusia (memory). Single or aggravated cardiovascular morbidity (including hypertension) was unrelated to test performance. Thus, some, but not all, common diseases may be associated with age related decline in cognitive ability. (RH). |
