Racism linked to cognitive decline in African American women

African Americans have higher rates of dementia and Alzheimer’s disease than white Americans. Chronic stress, associated with cognitive impairment and reduced volume in the brain’s memory area, could be a culprit. But racism may be one of the ultimate causes. And for African American women, the problem may be particularly pernicious. We are epidemiologists at Boston University. Our work is focused on the Black Women’s Health Study (BWHS), a landmark investigation that has followed 59,000 African American women since 1995. Previous data from our study showed that racism experiences are associated with increased risks of premature birth, obesity, Type 2 diabetes, uterine fibroids, adult-onset asthma and insomnia. More recently, we wanted to see how racism might impact cognition in African...

How COVID-19 might increase risk of memory loss and cognitive decline

Of all frightening ways that the SARS-COV-2 virus affects the body, one of the more insidious is the effect of COVID-19 on the brain. It is now clear that many patients suffering from COVID-19 exhibit neurological symptoms, from loss of smell, to delirium, to an increased risk of stroke. There are also longer-lasting consequences for the brain, including myalgic encephalomyelitis /chronic fatigue syndrome and Guillain-Barre syndrome. These effects may be caused by direct viral infection of brain tissue. But growing evidence suggests additional indirect actions triggered via the virus’s infection of epithelial cells and the cardiovascular system, or through the immune system and inflammation, contribute to lasting neurological changes after COVID-19.
