Question What is the association of cardiovascular health (CVH) levels, estimated by the American Heart Association’s Life’s Essential 8 score, with life expectancy free of major chronic diseases?
Findings In this cohort study of 135 199 adults from the UK Biobank study, high CVH level was associated with substantially longer life expectancy free of 4 major chronic diseases (cardiovascular disease, diabetes, cancer, and dementia) in both men and women. Furthermore, the disease-free life expectancy was similar between low and other socioeconomic groups among participants with high CVH.
Meaning These findings support improvement in population health by promoting a high CVH level, which may also narrow health disparities associated with socioeconomic status.

Patients with dementia are at higher risk for Covid-19 and are more likely to have worse outcomes, according to a new study published today.
The study, led by Case Western Reserve University researchers, reviewed electronic health records of 61.9 million adults in the United States and found that the risk for contracting Covid-19 was twice as high for people with dementia compared to the general population.
The risk was even greater still for African Americans with dementia, who were found to be close to three times as likely to be infected with Covid-19.
The study, which was published in the journal Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, also found that certain types of dementia had a greater risk than others.

The early prognosis of high-risk older adults for amnestic mild cognitive impairment (aMCI), using noninvasive and sensitive neuromarkers, is key for early prevention of Alzheimer’s disease. A recent study, published in the Journal of Alzheimer’s Disease, by researchers at the University of Kentucky establishes what they believe is a new way to predict the risk years before a clinical diagnosis. Their work shows that direct measures of brain signatures during mental activity are more sensitive and accurate predictors of memory decline than current standard behavioral testing.
“Many studies have measured electrophysiological rhythms during resting and sleep to predict Alzheimer’s risk. This study demonstrates that better predictions of a person’s cognitive risk can be made when the brain is challenged with a task. Additionally, we learned that out of thousands of possible brain oscillation measures, left-frontal brainwaves during so-called working memory tasks are good predictors for dementia risk,” explained lead investigator Yang Jiang, associate professor of behavioral sciences and an affiliated faculty member at the Sanders-Brown Center on Aging.
