The field of psychiatry is increasingly recognizing the importance of trauma and traumatic experiences, as evidenced by an extensive revision of the Post-Traumatic Stress Disorder diagnosis, as well as creation of a Trauma- and Stressor-Related Disorders section in the DSM 5. Conduct Disorder has also undergone an important clinical modification for the 21st century, with the addition of the specifier “with limited prosocial emotions.” However, full appreciation of the fundamental relationship of trauma to conduct-related disorders is still lacking. This symposium aims to demonstrate, through use of a case study and review of the literature, that understanding and treating trauma is a necessary and fundamental component of strategies to mitigate the potential negative long-term outcomes of Conduct Disorder.
