New evidence advances understanding of Long COVID

Recent studies indicate that symptoms of "long COVID," such as fatigue, shortness of breath, and problems with concentration and memory, may be linked to changes in blood coagulation, the immune system, and microvascular vessels. Research has revealed the presence of microscopic protein clumps and indications of disturbances in these small vessels, as well as an increased rate of blood clotting in patients. Although these findings provide potential evidence of causes for the persistence of symptoms, scientists have not yet proven that these changes are a direct cause or that they can be reliably used for diagnosis or treatment. Ongoing research continues to determine the extent of these changes’ impact on the disease and how to develop diagnostic and therapeutic methods based on them in the future.
