Abstract | INTRODUCTION: Little is known about functional limitations and health care resource utilization of people with cognitive impairment with no dementia (CIND). METHODS: Respondents with stable or progressive cognitive impairment (CI) after the first (index) indication of CIND in 2000-2010 were identified from the Health and Retirement Study (HRS). Respondents never exhibiting CI were identified as potential controls. Propensity score-based optimal matching was used to adjust for differences in demographics and history of stroke. Differences between cohorts were assessed accounting for HRS survey design. RESULTS: After matching, CIND respondents had more functional limitations (difficulty with ≥1 activities of daily living: 24% vs. 15%; ≥1 instrumental activities of daily living: 20% vs. 11%) and hospital stays (37% vs. 27%) than respondents with no CI (all P < .001). Seventy five percent of CIND respondents developed dementia in the observable follow-up (median time: ∼6 years). DISCUSSION: Even before dementia onset, CI is associated with increased likelihood of functional limitations and greater health care resource use. |
