Long Covid may lead to reduced brain oxygen levels, cognitive decline: Study
Covid-19 patients who were symptomatic were poor on two computer based tasks, one which measures inhibition and the other impulsive decision making.
The study said that compared to people who were not infected with Covid, the infected lack increase in oxygen saturation in an area of the brain that is usually engaged during the tasks. "We are the first to show reduced oxygen uptake in the brain during a cognitive task in the months following a symptomatic COVID-19 infection," said Peter Hall, lead author, and researcher at the University of Waterloo. "This is important because a lack of sufficient oxygen supply is thought to be one of the mechanisms by which COVID-19 may cause cognitive impairment," Hall added.
The other study as part of the research was a population survey of Canadians aged between 18 to 56 and it examined the relationship between COVID, cognitive function, and psychiatric symptoms.
According to the study, individuals who contracted COVID-19 experienced challenges with focus and inhibition, along with heightened symptoms of depression and anxiety.
