Psychological complexity: Barriers to its integration into the neurobiology of major psychiatric disorders

In the authors' experience interactions between clinical and laboratory research have been greatly mutually facilitatory in the understanding and development of new treatments for the major mental illnesses. Examples in the literature are also highlighted to show how cross-disciplinary studies are important in understanding the subtle interactions of genetic and environmental mechanisms in psychiatric illness. Yet, the results of some current science policies encouraging project focus and superspecialization can lead to the separation of clinical and basic investigators, which threatens the integration of psychological complexity into the neurobiology of psychiatry at both a molecular and behavioral level. This paper endorses renewed effort toward the multidisciplinary team approach under the leadership of a physician–scientist in order to better integrate many fields of study critical to ameliorating the effects of psychiatric illness.
