Posttraumatic stress disorder (PTSD) is a prevalent and disabling condition. The patients suffering from PTSD often consult primary care clinician for non-specific symptoms. The aim of this work is to find out useful clinical guidelines for diagnosis and therapy in primary care, starting from a literature review (1981-2009) and a preliminary observational study. 20 patients with PTSD had a specific trauma-focused psychotherapy, called "Trauma and Reintegration Psychotherapy (TRP)". This is a psychodynamic eclectic treatment combining Ericksonian Hypnosis and EMDR techniques. The results show a more important decrease of PTSD symptoms in patient's beneficiating of the TRP, than the average of the usual clinical studies. This could be linked to an early diagnosis made by the primary care general practitioners.
