IntroductionDespite increased risk of cognitive decline in Hispanics/Latinos, research on early risk markers of Alzheimer's disease in this group is lacking. Subjective cognitive decline (SCD) may be an early risk marker of pathological aging. We investigated associations of SCD with objective cognition among a diverse sample of Hispanics/Latinos living in the United States.MethodsSCD was measured with the Everyday Cognition Short Form (ECog-12) and cognitive performance with a standardized battery in 6125 adults aged≥50 years without mild cognitive impairment or dementia (x̄age =63.2 years, 54.5% women). Regression models interrogated associations of SCD with objective global, memory, and executive function scores.ResultsHigher SCD was associated with lower objective global (B=-0.16, SE=0.01), memory (B=-0.13, SE=0.02), and executive (B=-0.13, SE=0.02, p's&nbsp

BackgroundCardiovascular disease is linked to cognitive decline and disorders (e.g., dementia). The evidence is based largely on older non-Latino White cohorts.ObjectiveExamine the association between global vascular risk and cognitive function among Hispanics/Latinos in the United States.MethodsWe used data from a large sample of stroke- and cardiovascular disease-free, middle-aged and older Hispanics/Latinos with diverse backgrounds (n=7,650) from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). We compared associations between two measures of cardiovascular risk (CVR), the Framingham Cardiovascular Risk Score (FCRS) and the multiethnic Global Vascular Risk Score (GVRS), and cognitive performance using measures of global and domain specific cognitive function, and tested for modification by sex and age.ResultsHigher FCRS and GVRS were associated with lower global cognition and higher probability of low mental status, after covariates adjustment. Both CVR indices were associated with lower performances in learning and memory, verbal fluency, and psychomotor speed. Higher GVRS presented stronger associations with lower cognitive function compared to the FCRS. Women and younger age (45-64 years) exhibited more pronounced associations between higher CVR and worse cognition, particularly so with the GVRS.DiscussionCVR is also a risk for compromised cognitive function and evident in middle-age among Hispanics/Latinos. The multiethnic GVRS, tailored to specific risks based on racial/ethnic background, is feasible to use in primary care settings and can provide important insight on cognitive risk. Even modest shifts in population toward cardiovascular health in the high-risk Hispanic/Latino population can have important positive impacts on healthy cognitive aging.
