To a large extent, interventions in the field of child and adolescent mental health are guided by assessment inventories and treatment manuals based on diagnostic categories. A traditional diagnostic perspective may miss developmentally traumatised children’s heterogeneous presentation of symptoms, and may consequently make it difficult to develop an evidence base for interventions targeting their real needs. The Neurosequential Model of Therapeutics (NMT) is an alternative assessment approach, informed by advances in neurodevelopmental research. In this paper, we present NMT and show how the method was applied with a developmentally traumatised girl. We discuss to what extent changes in the girl’s functioning from before to after NMT might be attributable to the method. Against this background, we discuss if NMT can contribute to interventions and treatment strategies more tailored to developmentally traumatised children and adolescents’ needs.
