CNS Autoimmunity

CNS autoimmunity occurs when the immune system mistakenly attacks the brain and spinal cord, which make up the central nervous system (CNS). Normally, the immune system protects us from harmful invaders, but in autoimmunity, it targets healthy nervous tissue, leading to inflammation and damage. This can cause neurological symptoms like weakness, vision problems, or coordination issues. Diseases like multiple sclerosis are examples of CNS autoimmunity. The exact cause isn't always clear, but it involves a combination of genetic and environmental factors that lead the immune system to misidentify CNS components as threats.
