DSM-5 Overview and Goals
The road to DSM-5 spanned a decade of planning, discussion and review of the considerable advances in psychiatric research and clinical practice. By bridging the strengths of DSM-IV with the opportunities brought by new discoveries in neuroscience, the DSM-5 offers a foundation for future growth as we fill in our gaps of knowledge regarding the underlying pathologies of mental disorders. New features in DSM-5 include an organizational structure that permits alignment of disorders with shared putative pathogenesis irrespective of whether the disorders typically emerge in childhood or later in life. Other features include a new emphasis on risk factors and the development and life course of illness. The goal of the DSM-5 is to create a “living document” that may evolve over time as we gradually build on our knowledge of the neurobiologic underpinnings that account for both the emergence and lifetime expression of mental disorders.
