Childhood maltreatment is a major risk factor for reactive attachment disorder (RAD). We examined whether neural activity during reward processing was altered in children and adolescents with RAD using functional MRI. Significantly reduced activity in the striatum was observed in the RAD group compared with the TD group. And significant negative correlations between striatal activity and avoidant attachment were observed. The present results suggest that dopaminergic dysfunction occurs in the striatum of children and adolescents with RAD. Another study examined the neural effects of intranasal oxytocin on reward processing in children with RAD. Male children with RAD and TD individuals performed monetary reward task during functional MRI. Oxytocin enhanced striatal activation in the RAD group by the analysis of reward sensitivity using task contrast, but not in the TD group. These findings indicate that oxytocin may promote reward processing in RAD.
