How autoimmune encephalitis is caused

Autoimmune encephalitis is an inflammatory disease of the central nervous system that is primarily associated with an autoimmune response, which occurs when the patient’s immune system “misidentifies” his or her own brain tissue as a foreign antigen and produces an “attack” on it. “The specific antibodies and immune attack on the patient’s own brain tissue can be triggered by an infection and eventually lead to an inflammatory process in the brain tissue. The causative mechanisms are unknown and to a lesser extent may be related to predisposing factors such as tumours and infections, including teratomas, tumours (paraneoplastic syndromes) and herpes simplex virus/Mycoplasma/Streptococcus infections.
