Neurodevelopmental disturbance in the pathogenesis of major mental disorders

Neurodevelopmental disturbance may underlie the pathogenesis of major mental disorders, including autism and schizophrenia, based on evidence in epidemiology, clinical psychiatry, brain imaging, and neuropathology. This notion is further supported by the fact that many of genetic susceptibility factors for these disorders have key roles in neurodevelopment. Majority of these genetic factors, such as Neuroligins, SHANK3, Neureglin-1, Dysbindin, and Disrupted-in-Schizophrenia-1 (DISC1) are associated with "synapse." Therefore, "synapse" is one of the most promising sites of convergence in regard to molecular pathways for these mental conditions. In this review, we will summarize the updates of schizophrenia and autism research, with an emphasis on neurodevelopmental disturbances.
