While Complex-PTSD as a presentation is widespread, there is no corresponding DSM-5 Complex-PTSD classification and most clinicians are not trained to recognise or treat it. As a result, Complex-PTSD survivors are generally not diagnosed at all or misdiagnosed with the symptoms of their condition (depression, anxiety, substance or process addictions, relationship problems, eating disorders, personality disorders etc.). The outcome is unnecessary suffering and opportunity for healing lost as Complex-PTSD survivors can spend a lifetime treating surface symptoms with the underpinning aetiology left unaddressed. Even when Complex-PTSD is identified, treatment is often inappropriate, leading at best to minimal progress and at worst to further traumatisation. The aim of this interactive webinar, based on research and the facilitator’s clinical and personal experience of recovery, is to unpack and differentiate the relational trauma of Complex-PTSD from single-event trauma (i.e. PTSD) and help clinicians to understand its unique aetiology, manifestations and appropriate treatment so that their clients’ recovery is supported.
