The identification of a metabolic pathway could lead to answers and new treatments for those experiencing brain fog because of long COVID. Researchers from UNSW Sydney and St. Vincent's Hospital have identified a key pathway, involved in inflammation, which appears to be activated in people with long COVID who have symptoms of 'brain fog'. Scientists from the School of Psychology and Faculty of Medicine & Health found that of the study cohort of 128 people, those who had a prolonged activation of the kynurenine pathway were more likely to have mild cognitive deficits 12 months after developing COVID-19.
