Memory and concentration issues, fogginess, anxiety, depression, and loss of taste and smell: these are all neurocognitive symptoms of what is known as Long Covid Syndrome.
Antibodies and immunology
According to some clinical observations, the immune system of young Covid-19 survivors appears to age prematurely, contributing to the onset of Long Covid. But this ageing process could also be reversed
Solongevity Research, published by the international scientific journal in Immunology, addresses the issue of interactions between SARS-CoV-2 and other seasonal coronaviruses, immunological interactions that may explain the severe clinical course of some patients and the seasonal pattern.
As the immune system ages, it undergoes alterations and becomes less efficient. This is how processes such as immunosenescence and inflammaging affect it, exposing us to an increased risk of infection by pathogens such as the new coronavirus SARS-CoV-2.
The elderly are more susceptible to infections such as coronavirus SARS-CoV-2 due to phenomena such as immunosenescence and inflammation. At their origin, however, there are epigenetic changes that we can influence through our lifestyle.
