Treating complex developmental disorders can be challenging and often requires a skilled, nuanced approach that includes several different therapeutic approaches. Most clinicians use highly integrative ways of working, so that emotions, cognitions, somatic experience, relationships, and other domains of life are included in an individualized and tailored treatment that still follows the basic principles established for working with highly traumatized clients. This online course will explore the many options available to clinicians including medication, somatic work, psychodynamic approaches to defenses and resistance, EMDR, Internal Family Systems and other Ego State approaches, systems approaches, hypnosis, neuro-regulation, general stabilization, and relational approaches. The presenter will draw upon the clinical wisdom of the last 50 years of treatment approaches to complex developmental trauma symptoms and disorders and discuss what has worked and what has not, and with which kind of client. Finally, the presenter will explore a sequenced approach to working with complex trauma dissociation treatment that supports gradual integration and a nuanced balance between processing traumatic memories and focusing on creating positive experiences in the present, that is, developing a life worth living.
