Influence of cognitive functioning on functional status in an older population: 3‐ and 6‐year follow‐up of the Maastricht Aging Study

Abstract

Thus while cognitive functioning is useful clinically for predicting the short-term functional status of an older person, it is not useful for predicting that person's long-term (>3 years) functional status and thus the period of validity of the results of these tests in answering such questions is limited.
