Unraveling the Links: Long COVID, Brain Fog, Menopause, Gut Infection, and Low Hormone Levels
Researchers in France have proposed a hypothesis for the cause of long COVID brain fog, suggesting that brain inflammation triggered by COVID-19 may disrupt the regulation of glutamate by astrocyte cells, leading to cognitive fatigue. The study, based on PET scans of long COVID patients, identified a pattern of hypometabolism associated with astrocyte dysfunction and glutamatergic dysregulation. The authors propose targeting astrocytic glutamate regulation as a potential therapeutic approach. Further research is needed to establish a definitive link between reactive astrocytes and long COVID, and to understand the underlying mechanisms.
