Developmental Neuroscience Informs Policy Related to Migrant and Refugee Children's Mental Health

Migrant and refugee children commonly experience traumatic events and stressful conditions along their migration journeys. Migration-related trauma can have persisting effects on children's mental health. Developmental neuroscience suggests neural mechanisms that connect these experiences to mental health conditions such as post-traumatic stress disorder. This research review, focused on migrant families emigrating from Mexico, Central America, and Haiti and bound for the United States, first overviews the nature of trauma exposure faced by migrant families and next delineates potential neurobiological mechanisms underlying the effects of migration-related trauma on youth mental health. Finally, detailed policy recommendations relate to (1) providing mental health care, (2) addressing chronic stressors in the context of daily life, and (3) preventing migration-related trauma.
