A new study has found that severe new crown patients experience a decline in brain function within a few months of recovery. Some common cognitive problems include memory loss, brain fog, inability to concentrate continuously, and so on. The researchers say cognitive decline is equivalent to 10 years of brain aging.
A new study looking at the long-term effects of the new coronavirus suggests that recovering new crown patients can develop significant cognitive impairment even in the months after the initial diagnosis. The study, which included more than 84,000 people, is being peer-reviewed and was recently published on medRixv.
The study found that people with COVID-19 “performed worse than expected on cognitive tests in multiple areas because of their detailed age and demographic characteristics.” “It is important to note that cognitive problems were observed not only in patients with COVID-19 infection at the time, but also in patients who recovered weeks and months ago in other cases.
When patients with severe neo crown symptoms that require hospitalization, the researchers found that the new coronavirus can age the brain for about 10 years. This equates to an 8.5-point drop in IQ, the study said.
The observed decline was not small, with the global composite score for the hospital and ventilator subgroup dropping by 0.57SD, equivalent to an average global decline of 10 years between the ages of 20 and 70 in this data set. It fell even more than the average of 512 people who said they had had a stroke (-0.40SDs) and 1,016 people who reported learning disabilities (-0.49SDs). For comparison, in a classic intelligence test, 0.57SDs is equivalent to an IQ difference of 8.5 points.
A similar study from Northwestern University, involving 509 hospitalized coronavirus patients, found that 31 percent experienced encephalopathy, an all-en-enshroned term that includes a range of changes in brain function, including confusion, memory loss, attention problems, and even minor personality changes.
Part of the study is this:
At the time of discharge, only 32. 1% of people with encephalopathy are able to take care of their own affairs, compared with 89. Three percent of patients did not develop encephalopathy. In addition, the mortality rate was higher for patients with brain disease (21.7 per cent), while for those without encephalopathy it was only 3.2 per cent.
There is no doubt that one of the more frightening aspects of the new coronavirus is that it clearly affects a person’s health and cognitive function within a few months of recovery. It remains unclear whether patients who have experienced significant cognitive decline will be able to return to their pre-infection levels of brain function in the coming days.
