The article presents a case study in which the posttraumatic stress disorder (PTSD) was approached in an integrative, psychiatric and psychotherapist manner. The client, a highly hypnotizable person aged 65, diagnosed with PTSD and panic attacks, required, on the psychiatrist’s recommendation, specific pharmacotherapy combined with psychotherapy. The psychotherapeutic intervention consisted of 23 sessions using cognitive-behavioural hypnosis techniques that led gradually to treating the symptoms, while the psychiatric treatment was no longer needed. This case study highlights the characteristics of an integrative approach that combines psychological and psychiatric intervention techniques.
