title: [Suboptimal health and memory performance of elderly].
abstract: The influence of health-related incidents on memory test performance and subjective memory ratings was assessed in a) a group of healthy older adults recruited via the register of population (group 1: N = 117, mean age 62 years, range 46-89) and b) a group of healthy older subjects having memory complaints and applying for memory training (group 2: N = 111, mean age 63 years, range 45-85). The study tries to cross-validate a previous study, where the presence and frequency of health-related incidents were related to cognitive performance. The presence of 9 categories of health-related incidents (consultation of a neurologist, systemic diseases, repeated mild concussions, repeated anaesthesia, use of psychotropic medication, alcohol use, other neurotoxic factors, such as exposure to organic solvents, psychiatric disorders, birth complications or developmental problems) was assessed in a semi-structured interview. Memory performance was assessed with a battery covering different aspects of memory. Memory self-ratings were assessed with questionnaires asking for frequencies of memory failures and a general judgement of memory capacity. Health-related incidents occurred in about half of both subject groups and were not related to age or other demographic characteristics. In both subject groups, the presence, nor the number of health-related incidents was related to memory performance or memory complaints and there was no interaction with age. The results are not in agreement with the notion that health-related indices explain age differences in cognitive performance.
