A neurobiologically informed perspective on psychotherapy

Abstract

BackgroundPolarisation of biological and psychosocial aspects of psychiatry has promoted a form of Cartesian dualism. Current knowledge of the interaction between biology and psychology makes it possible to consider a truly integrative approach to treatment.AimsThe aim of this overview is to consider conceptual models of how psychotherapy may affect the brain.MethodThe literature discussing the mutual influence of genes and environment is surveyed. Relevant data involving the influence of psychotherapy on the brain are also reviewed.ResultsResearch findings suggest that the brain responds to environmental influence through the alteration of gene expression; that psychotherapy has specific measurable effects on the brain; and that implicit memory may be modified by psychotherapeutic interventions.ConclusionsAdvances in neuroscience research have led to a more sophisticated understanding of how psychotherapy may affect brain functioning. These developments point the way towards a new era of psychotherapy research and practice in which specific modes of psychotherapy can be designed to target specific sites of brain functioning.
