Doctors have already found that recovered Covid-19 patients have had brain fog. A disease that often manifests itself in a lack of concentration.
People infected with Covid-19 would have a greater risk of developing neurological diseases such as Alzheimer’s, Parkinson’s or stroke. This was revealed by a recent Danish study carried out on more than 900,000 Danes, of whom 43,375 tested positive for Covid-19. In the opinion of the doctors contacted by “Le Matin”, even more extensive studies are necessary to confirm these findings. Otherwise, “these figures can create panic among the populations”, they warn.
The link between the Covid-19 virus and the risk of eventually developing chronic diseases is still the subject of scientific research. The latest was carried out on more than 900,000 Danes, of whom 43,375 tested positive for Covid-19. It appears that people who have contracted Covid-19 would have a greater risk of developing neurological diseases in the long term. The researchers had, in fact, found that people who tested positive for Covid-19 had a 3.5 times higher risk of suffering from Alzheimer’s disease and 2.6 times greater risk of developing Parkinson’s disease. , compared to other negative patients. Their risk of stroke was 2.7 times higher and that of intracerebral hemorrhage was 4.8 times higher.
Commenting on these results, Dr Tayeb Hamdi, medical researcher in health policies and systems, believes that the relationship between viral infection and the development of chronic diseases, particularly neurological ones, is not new. He recalls, in this regard, that several people, including young people, had Parkinson’s disease, a few years after the influenza pandemic of 1918. And to add that scientists knew, from the appearance of Covid-19 , that this virus could be the cause of neurological and cerebral damage. “Their predictions were supported by the detection in some Covid-19 patients of what is called brain fog. “A disease that often manifests itself in a lack of concentration, a feeling of constantly being elsewhere or of not being as quick-witted as before,” explains the doctor-researcher.
Results to take with sparks
Dr Hamdi would like to point out that, at the same time, researchers are increasingly looking into the respiratory sequelae of Covid-19. Studies are multiplying to verify whether the virus promotes diseases such as asthma or tuberculosis. Questioned on this aspect, Dr Nadia Chafli, pulmonologist notes that, certainly cured of Covid-19 had respiratory sequelae, but nothing has been confirmed. “Studies are multiplying, but today we do not have the necessary hindsight to confirm the findings of researchers and to argue that Covid-19 would promote diseases, whether respiratory or neurological”. And to add that to have surer conclusions, it is necessary to be based on cross-sectional, analytical and comparative studies.
The pulmonologist also wishes to note that the studies, whose figures and data are very often shared by the laboratories, risk creating panic among the populations. For now, she adds, efforts must be concentrated to ensure protection against the virus. This point of view was supported by Dr. Hamdi who notes the need to take with sparks all the data found on social networks, citing international studies.
The expert thinks that citizens should instead be made more aware of the importance of protecting themselves against the virus by having reflexes such as wearing a mask in enclosed spaces, frequent hand washing and avoiding gatherings. These reflexes, which are added to vaccination, the role of which no longer needs to be demonstrated, are extremely important in order to be able to live with the virus without having to undergo more health restrictions.
