Coronavirus could age the brain by 10 years or cause IQ to fall, by Katie Gibson.
Coronavirus survivors may be at risk of lasting cognitive damage, according to a study that found that in the worst cases the infection can cause mental decline equivalent to an 8.5-point fall in IQ or the brain ageing 10 years.
The “brain fog” reported by many people weeks and months after their recovering from the virus may be a symptom of more serious cognitive deficits, scientists have said.
Research involving 84,285 people who had recovered from confirmed or suspected COVID-19 found that damage to the brain had happened to varying extents, depending upon the severity of the infection. However, more work is needed to identify how long this lasts. …
Those who had had no breathing difficulties but had tested positive also exhibited cognitive decline. People who had recovered at home had an average deficit equivalent to ageing five years or dropping four IQ points.
“This is a large enough difference that as an individual you would notice an impact on the ability to cope with your normal job and everyday life,” Dr Hampshire said.
This fits in with the impairment bioweapon theory. A few deaths among the old and sick are just a side effect.
Meanwhile, here is another example of the shocking economic carnage that results from applying a lockdown too late. London left it even later than Melbourne.
