Cognitive impairment reported after COVID-19 infection

HealthDay News – Cognitive impairment was reported after recovery from COVID-19, according to two studies presented at the Alzheimer’s Association’s annual international conference July 26-30 in Denver.

Gabriel de Erausquin, MD, Ph.D., of the University of Texas Health Science Center at the San Antonio Long School of Medicine, and colleagues conducted a prospective cohort study of senior Native Americans from Argentina to assess chronic neuropsychiatric consequences of severe acute respiratory syndrome Investigate coronavirus 2 (SARS-CoV-2) infection. Data from 233 SARS-CoV-2 infected participants and 64 controls were included. The researchers divided the sample into three groups: normal cognition, memory impairment, and multiple domain impairment (44.6, 21.0, and 34.4 percent, respectively). A correlation was observed between the severity of cognitive impairment and the severity of olfactory dysfunction, but no correlation with the severity of acute COVID-19.

George Vavougios, Dr. The researchers found that 56.2 percent of patients had cognitive decline, with a Montreal Cognitive Assessment (MoCA) score of <24. The predominant patterns of cognitive impairment were short-term memory disorders and multi-domain disorders with no short-term memory deficits. An association for the MoCA score with age, waist circumference, waist-to-hip ratio, and pulse oximetry oxygen saturation was observed during the six-minute walk test.

“A brain without oxygen is not healthy, and persistent deficiency can very well contribute to cognitive difficulties,” Vavougios said in a statement. “These data suggest some common biological mechanisms between the dycognitive spectrum of COVID-19 and post-COVID-19 fatigue that have been anecdotally reported in the past few months.”
