Epigenetics of Posttraumatic Stress Disorder and Somatoform Disorders in the Course of Psychotherapy
Not Provided

This reported observational clinical study aims at identifying epigenetic markers in a sample of patients undergoing high dose inpatient psychotherapy suffering from a variety of psychiatric/psychosomatic diseases such as somatoform disorders, posttraumatic stress disorder (PTSD), depression, anxiety disorders and eating disorders.

The exact epigenetic markers that will be traced are yet to define.

The investigators believe that

  1. Epigenetic patterns found in the group of psychiatric patients show differences from healthy controls
  2. Different diagnosis show differences in epigenetic patterns as well
  3. Epigenetic patterns correlate to the severity of the psychosocial disorder as measured in interviews or psychometric ratings
  4. Epigenetic patterns can change under inpatient high dose psychotherapy
  5. Changes correlate to clinical psychometric variables.

Non-Probability Sample

The present study includes all patients selected for multi-modal inpatient or day-clinic treatment in the department of psychosomatic medicine (as part of the centre of psychiatry)of the hannover medical school - given the informed consent of the patients. The patients treated in this unit are first seen in primary care and sent to us because of e.g. depression, somatization, eating-disorders, panic disorders, PTSD, or other psychiatric diseases commonly refered to as "psychosomatic" in Germany. They are subject to at least 2 diagnostic sessions in which further treamtment options are assessed.

For about one third of the patients with grave psychiatric disorders, intensive "multimodal" psychotherapy in an inpatient or day-clinic setting is recommended.

  • Psychiatric Disorder
  • Somatoform Disorders
  • PTSD
