"Uncovering the Root Cause of Long COVID Brain Fog"

A team of scientists from Trinity College Dublin and FutureNeuro has discovered that the brain fog and cognitive decline experienced by some Long COVID patients may be linked to disruption in the integrity of blood vessels in the brain. This "leakiness" of blood vessels was found to be a distinguishing factor in patients with brain fog and cognitive decline compared to those with Long COVID but without brain fog. The findings, published in Nature Neuroscience, suggest that understanding the underlying cause of these conditions could lead to the development of targeted therapies for affected patients. The research was supported by Science Foundation Ireland, the European Research Council, and FutureNeuro.
