List of mental disorders

The following is a list of mental disorders as defined at any point by the Diagnostic and Statistical Manual of Mental Disorders (DSM) or the International Classification of Diseases (ICD). A mental disorder, also known as a mental illness, mental health condition, or psychiatric disorder, is characterized by a pattern of behavior or mental function that significantly impairs personal functioning or causes considerable distress.

The DSM, a classification and diagnostic guide published by the American Psychiatric Association, includes over 450 distinct definitions of mental disorders. Meanwhile, the ICD, published by the World Health Organization, stands as the international standard for categorizing all medical conditions, including sections on mental and behavioral disorders.

Revisions and updates are periodically made to the diagnostic criteria and descriptions in the DSM and ICD to reflect current understanding and consensus within the mental health field. The list includes conditions currently recognized as mental disorders according to these systems. There is ongoing debate among mental health professionals, including psychiatrists, about the definitions and criteria used to delineate mental disorders. There is particular concern over whether certain conditions should be classified as "mental illnesses" or might more accurately be described as neurological disorders or in other terms.
