Understanding Neuroimmunology
Neuroimmunology studies how the immune system interacts with the central and peripheral nervous systems. While the immune system protects the body from infections, abnormal immune responses can mistakenly attack healthy nerve cells, resulting in inflammation and neurological damage.
Advancements in molecular biology, genetics, and diagnostic technologies have significantly improved the understanding of these disorders, enabling earlier diagnosis and more personalized treatment strategies.
