Neurobiology of Child Maltreatment and Psychological Trauma
Trauma is defined as exposure to an event or situation that overwhelms one’s capacity to cope, and threatens or causes harm to mental and physical well-being. This may include direct exposure, witnessing events, or learning about distressing experiences that happened to a loved one. Trauma can have deleterious consequences for children including increased risk for psychopathology, physical health problems, and impairment in several domains of functioning including emotion regulation, academic abilities, and social relationships. Examples of acute or short-lived traumatic experiences include natural disasters, sudden death of a loved one, a terrorist attack, or a number of other one-time occurring distressing events. Children also may experience trauma that is chronic in nature, such as witnessing frequent community violence or exposure to daily war-related violence.
