Covid disease can cause brain fog and dementia two years after infection – study – Axios

People infected with COVID-19 increased nervous system risks And psychological states such as brain fogpsychosis, seizures, and dementia for up to two years after infection.

News leadership: That’s according to a new large-scale Oxford University study that also found that anxiety and depression were more common after COVID, although they usually subside within two months of infection.

why does it matter: the studypublished in Lancet Psychiatry Wednesday’s Journal, is “the first attempt to examine some of the variability in ongoing neuropsychiatric aspects of COVID-19 in a large data set,” per accompanying opening.

  • “The findings have important implications for patients and health services as they indicate new cases of neurological conditions associated with COVID-19 infection that are likely to occur long after the epidemic has subsided,” said the study’s lead author. Paul Harrisonprofessor of psychiatry, in a statement.

recovery: Studying at Oxford University last year I found a third of COVID patients developed psychiatric or neurological illness six months after infection.

In numbers: In the latest study, researchers examined the risks of 14 different disorders in more than 1.25 million patients, ranging from children to the elderly who were mostly in the United States, two years after becoming infected with COVID.

  • She compared this information to the electronic records of 1.25 million people with other respiratory illnesses in the same period.

What they found: Adults 64 and younger who had MERS infection had a higher risk of developing brain fog (640 cases per 10,000 people) than those with different respiratory infections (550 cases per 10,000 people).

  • There were 1,540 cases of brain fog per 10,000 people in patients 65 and older who had COVID, compared to 1,230 cases per 10,000 for those with other respiratory infections.

while, There were 450 cases of dementia per 10,000 people and 85 cases of psychotic disorders per 10,000 among patients over 65 after COVID.

  • For other respiratory infections in this age group, there were 330 cases per 10,000 cases of dementia and 60 cases per 10,000 cases of psychotic disorders.

not worth anything The researchers found that children were more likely to develop epilepsy or seizures (260 out of every 10,000) within two years of contracting a COVID infection, compared to those who developed another respiratory infection (130 out of 10,000).

  • The risk of developing a mental disorder also increased, although the incidence is still rare – 18 out of every 10,000.

what are they saying: said Wes Elly, a professor at Vanderbilt University School of Medicine who researches COVID-19 STAT news The data showed that mood disorders and anxiety problems “prevalent in a prolonged period of Covid infection tend to resolve within months, which is good news” for patients.

  • Eli, who is also associate director of research at the VA Tennessee Valley Research and Education Clinical Center and was not involved in the study, added.
  • “Clinically, in my private practice and in our long Covid clinic, that’s exactly what we’re seeing: that the acquired dementia that these patients develop tends to be very persistent and problematic.”

bottom line, Via Harrison: The findings highlight the need for more research to understand why such neurological conditions occur after COVID “and what can be done to prevent or treat these conditions.”
