["Beware of coming too close to me"--development-oriented psychotherapy of a dangerous aggressive boy with early complex trauma experiences].

Early maltreatment of children can lead to severe disorders in the regulation of behaviour and affect, alterations in awareness and distorted perception. In development-oriented psychotherapy, therapeutic interventions which are directed to regulating processes, decentration or mentalization, desomatization and symbolization of enacted messages play a central role. The results of early traumatization and of therapeutic interventions are portrayed, examining the multi-dimensional diagnosis and therapy of a dangerously aggressive 12-year-old boy as an example.
