Current systems for diagnosis of mental disorders have their roots in 19th-century German psychiatry. DSM-5 and ICD-11 are categorical systems (well versus ill), while other systems take a dimensional approach. Dimensional approaches include the Research Domain Criteria (RDoC) development by the National Institute of Mental Health and the Hierarchical Taxonomy of Psychopathology (HiTOP). Currents efforts are focused on the identification of valid biomarkers for specific mental disorders and the development of precision medicine approaches in psychiatric practice. Associated with the incorporation of principles of precision medicine in psychiatry will be decision-support tools at the point of care that consider a patient’s genotype in decisions relating to optimal choices of a given treatment regimen. These challenges are especially critical to address given the significant contribution of mental disorders to the global burden of disease.
