Prior to these disorders being identified, and taking into account the severity and duration of symptoms, the clinical recovery of similar patients was not expected. This process can take up to 10 days and time is of the essence. The speed of recovery, degree of residual deficit, and frequency of relapse vary according to the type of autoimmune encephalitis. The most commonly studied subtype of AIE is Anti-N-methyl-D-aspartate receptor (anti-NMDA) encephalitis, so the management approach is primarily based on that. If all four criteria** match, the definitive diagnosis can be made. Immunotherapy and treatment of the tumorusually result in improvement.

A more refined form of PLEX called immunoadsorption has also been used to treat AE, and selectively removes antibodies from the blood, instead of all the other components that are also in the plasma. Many patients with encephalitis are left with residual physical or neuropsychological deficits which require long-term multidisciplinary management. Immunotherapy, such as steroids, intravenous antibodies (IVIg) or plasma exchange, to address certain types of autoimmune encephalitis.

It can also affect brain (cognitive) functioning, leading to confusion and behavior changes. The emergency care team will likely include specialists in infectious diseases, the brain and nervous system (neurologist). traveling to areas known to have encephalitis-causing viruses, Neuro-Visual and Vestibular Disorders Center. Those who remain refractory to first and second line treatment have benefited from Third-line/experimental treatments: IL6 blockade (tocilizumab) or plasma cell-specific therapy (proteasome inhibitors) or bortezomib, a treatment that depletes plasma cells.
