title: Residual effects of cigarette smoking on cognitive performance in normal aging.
abstract: The present study examined the residual effects of smoking status on cognitive function in 76 nondemented older adults. Current smokers, ex-smokers, and nonsmokers who were screened for health and intellectual impairments were administered a battery of standardized neuropsychological tests to measure problem solving, psychomotor speed, memory, attention span, perception, and language production. Performance decrements were found for smokers on measures of psychomotor speed. No between-group differences were noted on any of the nonspeeded tests. There were no differences between nonsmokers and ex-smokers on any measures. The results suggest that the residual effects of current cigarette smoking negatively influence speeded cognitive capabilities in older adults.
