"Link Between Long COVID and Brain Fog: Study Reveals Potential Cause"

A study by researchers at Trinity College in Ireland published in Nature Neuroscience found that long COVID patients with brain fog had increased permeability of their blood-brain barrier, indicating a potential biological mechanism for this symptom. The study involved specialized brain imaging and blood tests on 32 COVID-19 patients, revealing cognitive impairment and blood markers associated with inflammation and blood-brain barrier dysfunction. While the study has limitations and requires further research, it offers new insights into understanding and potentially treating long COVID symptoms, providing hope for future tests and treatments.
