Inflammation in vital brain region could be driving long Covid: Study

Symptoms of long Covid, including fatigue and brain fog, have been linked to damage to the brainstem or the brain region, which acts as a "critical junction" between consciousness and all that is physically happening in the body, according to a study.

The brainstem connects the spinal cord to two main parts of the brain -- cerebrum and cerebellum. Often dubbed as the 'control centre' of involuntary functions, the brainstem regulates basic life-sustaining activities such as breathing, heart rate and sleep, and located at the base of the brain.

Symptoms of long Covid have been studied to persist in some patients for up to two years following initial infection. The previous studies have found prolonged inflammation to be one of the main drivers of long Covid.

In this study, the researchers from the Universities of Cambridge and Oxford, UK, looked at high resolution MRI brain scans of 30 patients, who had severe COVID-19 early in the pandemic, and found that the infection caused ...
