Summary

At the moment, the number of people with long COVID is unkown because there is still no effective diagnosis. This is why is very important to analyze the most common symptoms, which are: depression, anxiety and fatigue. This project seeks to analyze some blood components of people with long COVID, such as microRNAs and vitamin B12, in order to identify the body processes that changed after COVID-19 and thereby design better therapies and diagnostic methods focused on each of them. The hypothesis is that the expression of miR-21, -146a and -155 will be overexpressed as well as there will be a deficiency of vitamin B12 in serum in subjects suffering from long COVID with neurological symptoms of depression, anxiety and fatigue.
