Patients recovering from Covid-19 experience brain aging
–
GridHEALTH.id – Attack re-infection of the corona virus on patient that recovered from Covid-19 has indeed haunted the whole world.
Even, re-infection of the corona virus it is more dangerous and more deadly.
But behind the shadow of re-infection with the corona virus, it seems that patients who recover from Covid-19 can also suffer significant brain function impacts.
Recent studies suggest that the adverse effects of coronavirus infection are linked to mental decline, which is equivalent to brain aging up to 10 years older than the age of a Covid-19 patient.

a study non-peer-review of more than 84,000 people, led by Adam Hampshire, a doctor at Imperial College London, found that in some severe cases, coronavirus infection was associated with substantial cognitive deficits over months.
“Our analysis is consistent with the view that there are chronic cognitive consequences as a result of Covid-19,” wrote the investigators in their report of findings. Reuters, Tuesday (27/10/2020).
“People who have recovered, including those who no longer report symptoms, show significant cognitive deficits,” he added.

Researchers used cognitive tests to measure how well the brain performed tasks, such as remembering words or joining dots on a puzzle.
Such tests are widely used to assess brain performance in diseases such as Alzheimer’s, and can also help doctors assess temporary brain disorders.
The Hampshire team analyzed the results of 84,285 people who completed the so-called study Great British Intelligence Test.
The findings, which have not been reviewed by other experts, are published online on the MedRxiv website.
“Cognitive deficits are a substantial effect size, especially among people who have been hospitalized with Covid-19,” the researchers said.
The worst case shows an impact equivalent to an average 10-year decline in global performance between the ages of 20 and 70.
Scientists not directly involved with the study, however, say the results should be viewed with caution.
“Participants’ cognitive function was not known prior to Covid-19, and the results also did not reflect long-term recovery, so any effects on cognition may be short-term,” said Joanna Wardlaw, professor of applied neuroimaging at the University of Edinburgh.

Derek Hill, a professor of medical imaging sciences at University College London, also noted that the study’s findings were not completely reliable, because they did not compare before and after scores, and involved a large number of people who reported themselves having Covid-19, who had no results. positive test.
“Overall, (this) is an interesting but inconclusive study of the effects of Covid-19 on the brain,” said Hill.
“As researchers seek to better understand the long-term impact of Covid-19, it is important to further investigate the extent to which cognition impacts in the weeks and months following infection, and whether permanent damage to brain function causes some people,” he added.
