ABSTRACT This study examined the relationship between multiple chronic conditions (MCC) and risk of cognitive impairment with no dementia (CIND) and dementia among older Americans. A sample of 637 individuals aged 70 or older was drawn from the Aging, Demographics, and Memory Study, a supplementary dataset of the larger national Health and Retirement Study. Multinomial logistic regression analysis was conducted to investigate the association between MCC and cognition categorized as (a) no cognitive impairment, (b) CIND, or (c) dementia. Having MCC, particularly three or more chronic conditions, was significantly related to being diagnosed with CIND in our study, but not dementia. Our findings suggest that the presence of MCC may be a risk factor for cognitive impairment in later life. However, further investigation using a longitudinal design is needed to better understand the mechanism of how MCC may be related to CIND and dementia among older adults in the United States.
