Abstract
Older adults are at risk for functional impairment in performing instrumental activities of daily living. Previous research has demonstrated that poor functional performance is associated with executive dysfunction. The current study investigated neuropsychological tests of executive function in determining functional ability in older adults. Fifty study participants consisted of community-dwelling and nursing home volunteers, and subjects referred for a neuropsychological. evaluation for assessment of dementia. Executive function tests accounted for 58% of the variance in functional status, with Trail Making Test-Part B demonstrating the strongest predictive power. Results also suggested that tests of executive function contribute significantly to the prediction of functional status, even after statistically controlling for memory function and global cognitive function. Depression had a low, statistically significant association with functional ability. In conclusion, results supported the hypothesis that common clinical measures of executive control predict functional status in older adults.
