Cognitive Screening Beliefs and Behaviors Among Older US Adults: Results from the National Poll on Healthy Aging

Background Fewer than half of people with dementia have been formally diagnosed by a clinician. Consequently, the US National Plan to Address Alzheimer’s Disease (AD) has prioritized early disease detection. A critical first step to early detection is primary care‐based screening for cognitive decline. Greater understanding of public perceptions and use of cognitive screening is needed to optimize early detection of AD among older adults. Method We analyzed data from the March 2023 fielding of the University of Michigan National Poll on Healthy Aging, a nationally representative web and telephone survey of community‐dwelling US adults aged 50‐80 using the NORC AmeriSpeak panel. Respondents for this analysis were aged 65‐80 without AD or dementia. Our primary outcome was self‐reported history of cognitive screening (never versus ever had screening). Logistic regression was used to estimate associations between respondent characteristics (i.e., sociodemographic factors, health factors, beliefs about cognitive screening) and self‐report of cognitive screening, and to examine whether primary care provider status moderates the association between screening beliefs and self‐report of screening. Result Of 1,242 respondents, 42% reported having ever undergone cognitive screening (21% within the past year). In adjusted analyses, sociodemographic factors (i.e., older age, higher level of education), insurance status (Medicare Advantage vs. traditional Medicare) and poorer physical health were associated with greater likelihood of cognitive screening (all p
