What is the best treatment for autoimmune encephalitis?
Treatment of autoimmune encephalitides includes immunotherapy, either corticosteroids or intravenous immunoglobulins (IVIG). When the condition is thought to be due to a cell-surface or synaptic protein antibody, IVIG, corticosteroids or plasmapheresis are initiated in various sequences and combinations.
What is paraneoplastic limbic encephalitis?
