Long Covid and Impaired Cognition — More Evidence and More Work to Do; New England Journal of Medicine
"The results of the study by Hampshire and colleagues are of concern, and the broader implications require evaluation. For example, what are the functional implications of a 3-point loss in IQ? Whether one group of persons is affected more severely than others is not clear. Whether these cognitive deficits persist or resolve along with predictors and trajectory of recovery should be investigated. Will Covid-19–associated cognitive deficits confer a predisposition to a higher risk of Alzheimer’s disease or other forms of dementia later in life? The effects on educational attainment, work performance, accidental injury, and other activities that require intact cognitive abilities should also be evaluated." more »
Stanford Medicine Study Identifies Distinct Brain Organization Patterns in Women and Men
“A key motivation for this study is that sex plays a crucial role in human brain development, in aging, and in the manifestation of psychiatric and neurological disorders,” said Vinod Menon, PhD, professor of psychiatry and behavioral sciences and director of the Stanford Cognitive and Systems Neuroscience Laboratory. “Identifying consistent and replicable sex differences in the healthy adult brain is a critical step toward a deeper understanding of sex-specific vulnerabilities in psychiatric and neurological disorders.” more »
Ferida's Wolff's Backyard: The Snow Turned Into Snowy Rain As It Fell From The Trees. Still Lovely ...
Ferida Wolff Writes: There was a slight rise in temperature and the snow started melting off the tree branches, splashing down like heavy rain. What was fluffy became squishy, thick and wet. It was very dramatic but shifted what started as an snowstorm into something new – it seemed to be raining snow! As our communities become more urbanized, the natural features around us tend to get pushed into the background and often go unnoticed." more »
NIH Study Offers New Clues Into the Causes of Post-infectious ME/CFS: Myalgic Encephalomyelitis/chronic Fatigue Syndrome; These findings, for the first time, suggest a link between specific abnormalities or imbalances in the brain and ME/CFS.
“People with ME/CFS have very real and disabling symptoms, but uncovering their biological basis has been extremely difficult,” said Walter Koroshetz, M.D., (seen right) director of NIH’s National Institute of Neurological Disorders and Stroke (NINDS). “This in-depth study of a small group of people found a number of factors that likely contribute to their ME/CFS. Now researchers can test whether these findings apply to a larger patient group and move towards identifying treatments that target core drivers of the disease.” Immune testing revealed that the ME/CFS group had higher levels of naive B cells and lower levels of switched memory B cells — cells that help the immune system fight off pathogens — in blood compared to healthy controls. more »
