Brain fog is a major issue for those with long COVID, and now researchers have found a link to leaky boundaries in the brain. MRI scans showed damaged blood vessels in the brains of patients with brain fog, leading to issues with memory and concentration. This is the first time leaky blood brain barriers have been observed in long COVID patients, shedding light on the biological basis of brain fog. The findings provide hope for potential therapies to address this troubling symptom. This information is crucial as it validates the experience of patients who may otherwise have their symptoms dismissed by healthcare providers.
