A new study conducted by researchers at the University of Cambridge and Imperial College London shows that coronaviruses can cause cognitive impairment equivalent to aging 20 years and losing 10 IQ points.
A person has a positive Covid test.
The study found that survivors of severe Covid-19 infections had cognitive impairments similar to aging that occurs between the ages of 50 to 70.
Researchers found that cognitive impairments were worse for people who had been put on a ventilator.
The study found that patients with severe Covid who were hospitalized for more than six months were more likely to have cognitive impairments than patients who were hospitalized for less than six months.
According to the researchers, the results suggest patients may need longer-term care for cognitive deficits.
The patterns we saw were distinct from all the others.
A growing body of research shows that people recovering from severe Covid can experience a range of long-term mental health and cognitive symptoms. A study of 740 people with no history of memory problems was conducted by the Icahn School of Medicine at Mount Sinai in October 2021. Unvaccinated people are more likely to develop long-term Covid symptoms than vaccine recipients. One of the first inquiries into the long-term effects of severe Covid was done by the University of Cambridge and Imperial College London.
Exactly what causes long-term cognitive effects. The body's inflammatory response and immune system are potential pathways, but researchers said future studies should focus on cognitive deficits to underlying issues in the body.
A new study finds that cognitive impairment is caused by COVID.
Unvaccinated people are more likely to get long covid and suffer symptoms for longer.
