Researchers offer hypothesis for long COVID brain fog
By Will Morton
A group in France has offered an explanation for long COVID brain fog, with the concept based on a visual brain pattern they discovered on patient PET scans.

Hypometabolism detected with F-18 FDG-PET in long-COVID patients: putative astrocyte dysfunction and glutamatergic dysregulation. (A) PET scan of a healthy subject. (B) PET scan of a long COVID patient. Hypometabolic areas are indicated with arrows. (C) A diagram showing a healthy condition in which an astrocyte has a normal capacity to take up glutamate and recycle it to sustain glutamatergic neurotransmission, giving rise to normal glucose utilization and lactate production to ensure adequate neuronal energy supply. (D) A diagram showing a long COVID condition in which an astrocyte has reduced glutamate uptake capacity, leading to reduced glutamate recycling, lower glucose utilization (observed with F-18 FDG-PET as hypometabolism) and lower lactate production, dysregulating glutamatergic neurotransmission, and possibly endangering neuronal survival.
