Millions of Americans are reportedly suffering from persistent symptoms long after recovering from a COVID-19 infection, according to a new study. These individuals, known as “long-haulers,” continue to experience a wide range of debilitating symptoms, including pain, fatigue, and cognitive issues.
Government surveys have indicated that there is a growing number of people living with neurological symptoms linked to long COVID. It appears that the virus indirectly causes damage to the brain, triggering an immune response that leads to inflammation in the brain even after the virus has been cleared from the body.
One of the impacts of COVID-related inflammation is the potential effect on the vagus nerve, which is responsible for memory and attention. This could explain the cognitive issues experienced by long-haulers.
The symptoms of long COVID are varied and can include pain, poor sleep, and unreliable memory. Even individuals who experienced a mild case of COVID-19 can suffer from long-term changes in their immune system that affect the brain and nervous system.
Recent evidence suggests that immune activation can damage brain cells, irrespective of whether the virus itself directly infects them. This has led to comparisons between long COVID and autoimmune diseases, where the immune system mistakenly attacks healthy cells.
Studies conducted on mice have shown that long COVID weakens the blood-brain barrier, allowing the immune response to impact brain cells, leading to inflammation and changes in the brain.
Researchers are currently testing drugs that target inflammation as a potential way to protect the brain after COVID infection. Preliminary results indicate that these drugs may be effective in improving symptoms related to long COVID.
One way to reduce the risk of developing long COVID is through vaccination. By getting vaccinated, individuals can protect themselves against the virus and potentially avoid the long-term consequences associated with it.
Michelle Wilson, a long-hauler who contracted COVID-19 before the availability of vaccines, remains hopeful for new treatments that can improve brain function and overall quality of life. Like many long-haulers, she is eagerly awaiting developments in medical research to mitigate the long-term effects of the virus.
As the number of long-haulers continues to rise, it is crucial to raise awareness about the persistent symptoms associated with COVID-19 and the potential long-term impact on the brain and nervous system. Through ongoing research and the development of new treatments, it is hoped that long-haulers will find relief and improved quality of life in the near future.
