Research focus

In recent years, there has been a dramatic increase in the awareness of immunological encephalopathies in neuropsychiatry. Several case reports and case series have reported immunological encephalopathies mimicking dysexecutive, psychotic, depressive, and demential syndromes. Pathophysiologically, antineuronal antibodies against neuronal cell surface antigens (e.g., NMDAR-antibodies), against intracellular synaptic antigens (e.g., GAD-antibodies), and against intracellular onconeural antigens (e.g., Hu-antibodies) need to be distinguished. Moreover, thyroid autoantibodies (e.g., TPO-antibodies) could be associated with steroid responsive encephalopathy in patients with autoimmune thyroiditis (SREAT-syndrome). Epileptic and paraepileptic phenomena seem to play an important role in the clinical presentation of IEs. Therapeutic approaches with immunomodulatory treatment (e.g., corticosteroids, plasmapharesis) are promising, but clear therapeutical algorithms are still missing. Our neuroimmunological research focuses on underlying pathomechanisms and on identifying therapeutic opportunities and algorithms.
