Severe Covid: Another 20 years for the brain!

Fatigue, brain fog, difficulty finding words, sleep disturbances, shortness of breath, anxiety, depression, post-traumatic stress …: Since the emergence of the Covid-19 virus – contaminating more than 500 million people worldwide (for recorded cases) – more And more observations indicate that it causes permanent mental disorders. But there has been a lack of study analyzing the really failing cognitive skills of people with the virus, and that’s in the long run.

Here it is, and that’s not really good news, as it only worsens the previous results. In fact, doctors and neurologists from the University of Cambridge and Imperial College London regularly tested the mental health of 46 people with Covid-19 who received intensive care at Addenbrooke Hospital. (16 of them had to be ventilated), between March 10, 2020 and July 31, 2020. They appear to have lost 10 IQ points, which equates to normal brain aging between 50 and 70 years…

More specifically, the researchers gave them, as far as possible, cognitive tests as well as tests with questionnaires to measure anxiety, depression, and PTSD. This is for six to ten months after the acute phase of Covid-19 infection for each patient.

The result: All subjects were significantly less accurate in carrying out tasks and much slower than people who had never had Covid-19 answering multiple questions for tests and rating scales. The effects are most pronounced in individuals who have to breathe in order to breathe. More specifically, people who have contracted the virus show a deficit in verbal reasoning and therefore have difficulty finding their words; Their cognitive processing speed is also slower, so they experience less attention and short-term memory, and therefore have more difficulty solving complex problems.

long recovery…

Altogether, the researchers are of the opinion that the former patients showed an IQ loss of 10 points, six or ten months after injury, that is, twenty years of normal cerebral aging plus … but some people seem to regain more effective kidneys after about ten months – infection. However, according to the researchers, cognitive defects are of particular importance because the disease is initially serious, persists for a long time in the chronic phase and is slowly absorbed, if at all. For David Menon, who was involved in the study, it would be a “deep brain fingerprint of Covid-19”. Therefore, the patients concerned should benefit from long-term support in order to restore better brain function. But why these cognitive disorders?

On ignore encore exactment comment le virus du Covid-19 perturbe le cerveau, mais quelques pistes, notamment liées aux complications neurologiques des soins intensifs, peuvent rendre compte de ces troubles cognitifs persistants: un manque d’oxygène, une inflammation ut des cérédébra Blood vessels. For example, another recent study found evidence of a form of brainstem inflammation in severe Covid cases. However, all of these brain problems can cause neuronal dysfunction and thus cognitive difficulties, sometimes irreversible. And that counts without the health measures and restrictions associated with the pandemic, including another study also published this month in scalpel, She asserts that they are directly related to the risk of stress, suffering from anxiety, depression, and even post-traumatic stress – thus questioning the benefit-risk balances of “zero transmission” and “zero virus” policies in relation to the number of deaths.
