Refugees, like most other migrants, are at increased risk for various forms of psychopathology. This paper documents the relationship between refugee migration and psychopathology by reviewing pertinent epidemiological, clinical, and survey studies from the refugee literature. The picture that emerges shows consistently increased levels of serious psychopathology (both psychotic and non-psychotic) and high symptom levels across widely different refugee groups. A number of symptoms, syndromes, and disorders that occur with greater frequency among refugees are discussed and summarized. These include depressive syndromes or affective disorders, paranoid syndromes, schizophrenic disorders or brief reactive psychoses, organic brain syndromes such as mental retardation and learning disorders, somatic or psychophysiological disorders, anxiety and post-traumatic stress disorders, substance abuse, antisocial personality or conduct disorder, and other conditions, including "culture bound" disorders.
