NMDA receptor encephalitis and other antibody-mediated disorders of the synapse: The 2016 Cotzias Lecture.

Investigations during the last 10 years have revealed a group of disorders mediated by antibodies against ion channels and synaptic receptors, which cause both neurologic and psychiatric symptoms. In this review, I discuss the process of discovery and immunologic triggers of these disorders, and use anti-NMDA receptor encephalitis to emphasize the importance of understanding the underlying physiopathologic mechanisms in those diseases. A better knowledge of these mechanisms reveals points of convergence with other disorders (e.g., schizophrenia), suggests treatment strategies beyond immunotherapy, and is helping us understand how memories are formed and retrieved.
