Fine tuning recommendations for older adults with memory complaints: using the Independent Living Scales with the Dementia Rating Scale

Abstract

The purpose of this study was to describe how functional test performance changed as global cognitive functioning dropped, as well as to examine the relationship of demographic variables and depression with functional test results. We found that level of performance on the Independent Living Scales (ILS) correlated highly with Dementia Rating Scale (DRS) scores in 83 older adults presenting for clinical neuropsychological assessment, while correlations with demographic factors and depression were nonsignificant or modest. Based on DRS scores, we divided our sample into four groups: normal cognitive status, borderline cognitive impairment, likely mild dementia, and likely moderate dementia. ILS profiles of the borderline impairment and mild dementia groups were similar and reflected particularly poor performance on subscales tapping financial management and everyday memory. Individuals with likely moderate dementia were markedly impaired on all subscales.
