New findings by scientists have revealed that there are molecular signatures in the blood that are linked to brain fog, cognitive problems, and fatigue in patients with long Covid. The study, which analyzed blood proteins in over 1,800 hospitalized Covid patients, found that higher levels of fibrinogen and D-dimer were more common in individuals experiencing long-term cognitive issues.
Fibrinogen and D-dimer are proteins that indicate the presence of blood clots in the body. The study suggests that these blood clots could be responsible for the reported symptoms of brain fog, memory problems, and fatigue in long Covid patients. This supports previous research indicating that Covid can leave some patients with blood clots in their lungs and potentially in their brains, resulting in long-lasting cognitive difficulties.
These findings have significant implications for the treatment of long Covid. Clinical trials testing anticoagulants could potentially improve brain fog and fatigue in patients, while monitoring blood protein levels could help identify individuals at risk. However, further research and clinical trials are needed to establish clear treatment mechanisms.
While a blood test for fibrinogen and D-dimer could potentially identify Covid patients at risk for long-term cognitive symptoms, it may not capture all individuals at risk. Therefore, health officials must consider alternative methods to ensure all patients receive the necessary attention and treatment.
In addition to the ongoing challenges of long Covid, health officials in England are now concerned about a new, highly mutated variant of the virus that has been detected in the country and other nations. This further emphasizes the urgency of addressing the long-term consequences of Covid and providing adequate support and treatment to affected individuals.
Many patients with long Covid feel they have little support and limited access to treatment options. It is crucial for healthcare systems to prioritize the needs of these individuals and ensure they have access to the necessary resources and care. With the identification of these molecular signatures in the blood, there is hope for improved understanding and management of long Covid. However, concerted efforts and further research are essential to address this complex and debilitating condition.
