Mental health and immigration.

The author reviews the psychosocial implications of immigration. Immigration is a complex, emotionally charged process which involves leaving behind old values, relationships, security, and resettling in an unknown culture with a new set of norms and boundaries. Some studies report a higher incidence of psychiatric illness in a migrant population than among the native born. Preventive and early therapeutic intervention is mandatory. In order to facilitate acculturation and eventual adaptation, the host society should promote easy access to the health-care systems, educational facilities, housing requirements and community organizations.
