Here is a short informative video from the Autoimmune Encephalitis Alliance. It is presented by Dr. Heather Van Mater who is a pediatric Rheumatologist.
What is meningitis? What is encephalitis?
Infections, and less commonly other causes, in the brain and spinal cord can cause dangerous inflammation. This inflammation can produce a wide range of symptoms, including fever, headache, seizures, change in behavior or confusion and, in extreme cases, can cause brain damage, stroke, or even death. Infection of the meninges, the membranes that surround the brain and spinal cord, is called meningitis. Inflammation of the brain itself is called encephalitis. Myelitis refers to inflammation of the spinal cord. When both the brain and the spinal cord are involved, the condition is called encephalomyelitis. What causes meningitis and encephalitis? Infectious causes of meningitis and encephalitis include bacteria, viruses, fungi, and parasites. Many of these affect healthy people. For others, environmental and exposure history, recent travel or immunocompromised state (such as HIV, diabetes, steroids, chemotherapy) are important elements. There are also non-infectious causes such as autoimmune causes and medications.
