On the role of neurobiological and genetic factors in the etiology and pathogenesis of suicidal behavior among immigrants.
Immigrants have higher rates of suicidal behavior than those in their countries of origin and their new countries. Immigration is a stressful life event which may lead to depression and suicidal behavior. Depressive disorders and suicidal behavior have a firm neurobiological and genetic basis. The author suggests that most immigrants who exhibit suicidal behavior in the new country had suicidal tendencies, and/or some degree of depression, and/or certain maladaptive personality traits in their countries of origin. The paper emphasizes the role of genetic and neurobiological factors in the human response to stressful events.
