[A gerontopsychological pilot study on the sleep of the very elderly--initial experiences with the Nürnberg Gerontopsychologic Inventory].

In an ongoing study of sleep in aged seniors the relationship between physiological, pathophysiological changes of sleep parameters and cognitive function was studied. It will be argued that the Nuremberg gerontopsychological inventory is superior to commonly used psychometric test-batteries to assess cognitive function in the aged. Preliminary results on the application of the Nuremberg gerontopsychological inventory will be presented, which were achieved in 10, non-demented, independently living subjects aged 80 to 85 years. The relationship between subjective complaints on aging, everyday activities and psychometric assessed performance was analyzed in detail.
