Autoimmune disorders are diseases in which the body’s immune system attacks healthy tissue. These disorders can affect many different parts of the body. In our Neuroimmunology Center at Boston Children’s Hospital, we care for children and adolescents who have autoimmune disorders that affect their central nervous system (the brain and spinal cord).
These diseases are referred to as neuroimmune conditions. They include “demyelinating” disorders such as multiple sclerosis — in which the immune system damages the protective covering of nerves. Some neuroimmune conditions can also affect the lining of the brain (autoimmune meningitis), the brain itself (such as autoimmune encephalitis, autoimmune epilepsies), the nerves to the eyes (optic neuritis), and other nerves to the head and face, and the spinal cord (myelitis).
Some autoimmune conditions that affect the body generally, such as lupus, can also affect the nervous system. We care for patients with these conditions, as well. Sometimes the immune system may attack the body after becoming activated during an infection. In this case, the immune system is no longer fighting the infection, but, instead, turns against otherwise healthy body tissues and attacks them.
Certain infections themselves can also directly affect the nervous system (in infectious meningitis, encephalitis, and myelitis, for example). Our Neuroimmunology Center also cares for children with these various neurological infections. We have physicians who have additional specialization and expertise in conditions such as acute flaccid myelitis and arboviral encephalitis (West Nile virus, Eastern equine encephalitis, Powassan virus encephalitis, etc.).
