Childhood maltreatment (MALTX), including emotional abuse, physical abuse, sexual abuse and neglect, is widespread in US. MALTX has been known to produce long-lasting impairments in behavioral, cognitive and social functioning, but their underlying mechanisms are not well-understood. The developing brain is highly sensitive to the effects of early-life stress. In this study, 19 MALTX adolescents and 13 age-matched controls were recruited and underwent DTI scanning. The goal of this study is to find out if white matter disruption precedes the onsets of clinical symptoms and may serve as potential biomarker of pscychiatric disorders such as depression and substance abuse.
