Abstract
This study examines longitudinal changes in cognitive functioning over the course of 2 years in participants of adult day cae programs. Cognitive measures included the Brief Cognitive Rating Scale (BCRS) and the Mini-Mental State Examination (MMSE). Longitudinal data were available for five measurement points over 2 years for 82 participants (22 males and 60 females). Overall, results from this study suggest that there were significant cognitive declines on BCRS and MMSE, even after only 1 or 2 years in the study. The rates of impairment over the 2 years for BCRS and MMSE were highly correlated. Within each measure, the individual rates of decline were very heterogenous and were influenced by the presence, type, and prognosis of dementia. Participants with multi-infarct dementia had greater cognitive decline than did those with other types of dementias. Initial cognitive functioning and physician's prognosis of dementia trajectory were also significant predictors of change over time. Results suggest a floor effect in the BCRS.
