The "brain fog" of long COVID might be due to impaired lung function following a person's infection, a new study says.

The brain "fog" often reported by people with long Covid may be linked to lung function, according to a recent study.Scientists have discovered a potential connection between diminished pulmonary gas exchange and the concentration difficulties experienced by individuals dealing with long-term coronavirus effects.

In patients with long COVID, lower pulmonary gas exchange may be associated with impaired cognitive function, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA).

Study senior author Dr. Sean Fain said: “If these findings can be generalized to the long Covid population, the study suggests that there may be a causative relationship between cognitive dysfunction and lung dysfunction, suggesting a potential treatment strategy using methods that target improved gas exchange.”
