Autoimmune encephalitis (AE) is an acute inflammation of the brain resulting from body's own antibodies attacking brain tissue (e.g. neuronal cell-surface antigens such as extracellular epitopes of synaptic receptors) and impairing its function.

Seronegative patients who have the clinical features of autoimmune encephalitis respond as well to immune therapy as seropositive patients - likely due to the presence of unrecognized autoantibodies (Hacohen et al, 2013). First line immunotherapy typically includes intravenous methylprednisolone and IVIg or plasmapheresis.

In children, 46% of all cases with probable diagnosis of AE were found to be mediated by autoantibodies, against NMDAR in 27% and against VGKC-complex proteins in 17% (5).
