The sequelae of long covid infection have a greater impact on cognitive ability than stroke
Symptoms called 'brain fog' have been reported as sequelae of the new coronavirus infection (COVID-19), such as poor concentration, loss of sense of direction, and inability to understand correct words. When an ability measurement test was actually conducted on a scale of 80,000 people, COVID-19-infected persons had a lower test score than non-infected persons, especially in the case of severely ill patients who were equipped with a ventilator, IQ 7 points. It is said that a score decrease corresponding to was seen.

Large study finds COVID-19 is linked to a substantial drop in intelligence
It has been reported that COVID-19 ' may cause serious brain damage even if the symptoms are mild'. In fact, some people still suffer from dementia-like symptoms called 'brain fog' after recovery.
What is the reality of 'dementia-like symptoms' experienced by some people who have recovered from the new corona? --GIGAZINE
Adam Hampshire and colleagues at Imperial College London used data from 81,337 collaborators to investigate the effects of COVID-19 on cognitive function. Hampshire and colleagues conducted nine types of cognitive ability measurement tests.
As a result, COVID-19-infected individuals scored lower than non-infected individuals. The areas that were particularly affected were those that required 'reasoning,' 'planning,' and 'problem solving,' which were consistent with the symptoms of 'brain fog.'
In addition, the extent of the decline in cognitive ability was also associated with the degree of symptoms, and the decline in score was particularly noticeable for those who 'worn a respirator.' The amount of decrease is equivalent to IQ 7 points in the classic intelligence test. The score of the severely ill was lower than that of the person who suffered a stroke or had a learning disability.
