Campus Clinic Symposium
NMDAR Hypofunction at the Crossroads of Psychosis and Cognition: Insights from Schizophrenia and Anti-NMDAR Encephalitis
December 9-10th. Centre Esther Koplowitz, IDIBAPS.
Symposium Speakers
Abstract
Schizophrenia is a complex psychiatric disorder with elusive biological underpinnings. Among competing theories, the glutamatergic hypothesis—which posits a hypofunction of N-methyl-D-aspartate receptors (NMDARs)—has gained substantial empirical support. In parallel, anti-NMDAR encephalitis, an autoimmune disease in which antibodies target and disrupt NMDARs, offers a distinct yet mechanistically convergent perspective on NMDAR dysfunction in the human brain.
This workshop brings together experts from molecular psychiatry, immunology, and cognitive neuroscience to explore the role of NMDARs in both pathophysiology and cognition, through the lens of these two conditions. The first part of the workshop will focus on the molecular and cellular mechanisms that implicate NMDAR hypofunction in schizophrenia, including evidence from genetic, pharmacological, and post-mortem studies. The discussion will then pivot to anti-NMDAR encephalitis, highlighting its clinical features, immunological basis, and the insights it offers into receptor-level disruptions.
Despite vastly different etiologies, both disorders manifest overlapping symptoms, such as psychosis and severe cognitive impairments, raising compelling questions about shared circuit-level vulnerabilities. Building on this comparison, the final segment of the workshop will examine the role of NMDARs in working memory—a basic cognitive function similarly disrupted in both conditions. By using these two clinical syndromes as naturalistic "models" of NMDAR disruption, we aim to shed light on whether NMDARs are not only necessary but also fundamentally involved in sustaining working memory processes. This session will integrate findings from human experiments, computational modeling, and animal studies to propose a mechanistic framework linking receptor-level dysfunction to cognitive deficits.
By weaving together insights from psychiatry, neurology, and systems neuroscience, this workshop aims to advance our understanding of NMDAR function in health and disease, and to stimulate interdisciplinary discussion on how converging biological mechanisms can inform future diagnostic and therapeutic strategies.
