[Diagnostic Workup and Treatment of Antibody-Related Encephalomyelitis]

The results of laboratory tests for antineuronal antibodies in immune-mediated encephalitis nowadays are not only relevant for diagnostic purposes but are instead closely connected to outcome measures and treatment response. Besides the mere detection of antibodies, investigating the cerebrospinal fluid is indispensible to rule out an infectious etiology of encephalitis prior to the initiation of immunosuppressive treatment, whereas imaging studies are relevant to gain information on the temporal course of disease and for ruling out other etiologies, e. g. hippocampal gliomas. This work gives an overview on the clinical course and findings of laboratory, electroencephalography (EEG) and imaging studies in relevant types of autoimmune mediated encephalitis. Furthermore, it gives a synopsis on contemporary treatment strategies.
