Abstract
Background: Antibody-mediated and paraneoplastic autoimmune encephalitides (AE) present with a broad
spectrum of clinical symptoms. They often lead to progressing inflammatory changes of the central nervous system
with subacute onset and can cause persistent brain damage. Thus, to promptly start the appropriate and AEspecific therapy, recognition of symptoms, initiation of relevant antibody diagnostics and confirmation of the
clinical diagnosis are crucial, in particular as the diseases are relatively rare.Aim: This standard operating procedure (SOP) should draw attention to the clinical presentation of AE, support the
diagnostic approach to patients with suspected AE and guide through the necessary steps including therapeutic
decisions, tumour screening and exclusion of differential diagnoses.Method: Based on existing diagnostic algorithms, treatment recommendations and personal experiences, this SOP
gives an overview of clinical presentation, diagnostic procedures and therapy in AE. Additional information is
provided within an accompanying text and a table describing the most important autoantibodies and their characteristics.Results: The initial steps of the AE flow chart are based on clinical symptoms and the patient’s history. Assignment
to paraneoplastic or antibody-mediated AE is sometimes clinically possible. Diagnostics should include MRI, EEG
and CSF analysis with antibody panel diagnostic. Definite AE can be diagnosed if the underlying antibody is
compatible with the clinical presentation. Classification of probable AE may be possible even with negative antineuronal autoantibodies if the clinical presentation and laboratory abnormalities are highly suggestive of AE. The
confirmed AE diagnosis requires immediate initiation of immunotherapy.Conclusion: The SOP facilitates the recognition of patients with AE and presents the necessary diagnostic and
therapeutic steps.Keywords: Autoimmune, Encephalitis, Limbic encephalitis, Antibody, Paraneoplastic, NMDAR
