Unveiling the Hidden Impact of Long COVID: New Findings and Treatment Breakthroughs

Researchers from the University of New South Wales and St. Vincent's Hospital have discovered a key biological pathway, known as the kynurenine pathway, that is activated in people with long COVID and is linked to the cognitive challenges commonly referred to as "brain fog." The study found that patients with prolonged activation of this pathway were more likely to have mild cognitive deficits even 12 months after developing COVID-19. The identification of this pathway could lead to potential treatments for brain fog and provide a diagnostic marker for long COVID. The findings highlight the biological basis behind long COVID's cognitive effects and offer hope for those experiencing long-term symptoms.
