| dc.description.abstract | Current classification systems for identifying individuals at the earliest stages of dementia, based primarily on cognitive measures, may be limited in scope. The present study examined physical functioning in a sample of 304 nondemented, older adults, classified based on presence and severity of mild cognitive impairment. In general, lower levels of physical functioning and greater inconsistency in physical functioning were found in older participants and in participants with increasing severity of cognitive impairment. Evaluation of the combined and unique contributions of level of and inconsistency in physical functioning to predicting cognitive status group membership revealed that, for some physical measures, inconsistency in physical functioning provided unique information beyond level of performance. These results are consistent with the notion that inconsistency in performance may be a behavioural marker of compromised neurological functioning and that information regarding physical functioning may prove useful for identifying individuals at the earliest stages of dementia. | en_US |
