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.

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.

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.

Covid condition, referred to as long Covid. People with long Covid experience a range of symptoms, including problems concentrating sometimes referred to as “brain fog,” change in sense of smell or taste,
