Objective:
Youths with disruptive behavior disorders (DBDs) and a history of trauma exposure often exhibit deficits in neural mechanisms related to reward anticipation and assessment. This preliminary investigation examines the potential of a serotonergic agent (fluoxetine) to modulate neural activity in reward-related pathways for this population.
Methods:
Three participant groups were: (i) youth with DBDs and trauma exposure who received fluoxetine treatment for 8 weeks (n = 12); (ii) a matched group of youth with DBDs and trauma exposure who received routine regular followup in an outpatient clinic (n = 9); and (iii) typically developing youth (n = 19). All participants completed a passive avoidance fMRI task twice, 8 weeks apart (pre-treatment and post treatment for youth with DBDs).
Results:
Youth with DBDs and trauma exposure who received fluoxetine treatment compared to the other two groups showed: (i) significant improvement in externalizing, oppositional defiant disorder, irritability, anxiety-depression, and trauma-related symptoms; (ii) significantly increased recruitment of regions implicated in reward expectation (e.g., ventral tegmental area, nucleus accumbens), monitoring prediction error (e.g., dorsolateral prefrontal cortex, posterior parietal cortex), and inhibitory control (e.g., anterior insula, pre-supplementary motor area, anterior prefrontal cortex.
Conclusion
We provide preliminary data suggesting that a serotonergic medication can correct reward processing and provide symptom improvement in youth with DBDs and a history of trauma exposure. Given the small sample size, more rigorous studies with larger sample size are needed to confirm these results. The findings of this study could aid future clinical research and treatment for this challenging population.

OBJECTIVE: We monitored a group of students from Danwon High School who survived the Sewol ferry disaster for 27 months to examine the course of their psychological symptoms. METHODS: We performed a chart review at the Danwon High School Mental Health Center at the following time points (T): 9 months (T1), 12 months (T2), and 15 months (T3) after the disaster. Additionally, we performed a follow-up review at 27 months (T4). Subjects completed the ‘State’ section of the State-Trait Anxiety Inventory for Children, the Center for Epidemiological Studies-Depression assessment, the Child Report of Post-traumatic Symptoms, and the Inventory of Complicated Grief. Data from the 32 subjects who completed all four assessments were used in the statistical analyses. RESULTS: Scores of psychological variables tended to increase until T2 and then slowly decreased until T4. The severity of anxiety and complicated grief symptoms changed significantly over time, but the severity of depression and posttraumatic stress symptoms did not. CONCLUSION: We found that the symptoms of anxiety and complicated grief reported by Sewol ferry survivors from Danwon High School were exacerbated at the first anniversary of the disaster, but these symptoms subsided after the students graduated from high school.
