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.

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

Lower rates of gas exchange in the lungs may contribute to impaired cognitive function ("brain fog") tied to long COVID, according to a small study to be presented at next week's Radiological Society of North America's (RSNA's) annual meeting in Chicago.

A new study suggests that difficulty concentrating, often called “brain fog,” in people with long COVID may be connected to how well their lungs exchange oxygen and carbon dioxide. The findings, presented at the Radiological Society of North America’s annual meeting,

A NOVEL study using advanced MRI techniques has revealed that impaired pulmonary gas exchange in the lungs of long COVID patients may be linked to cognitive difficulties, according to findings set to be presented at the Radiological Society of North America (RSNA) annual meeting in Chicago, Illinois, USA.

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.”
