 The aim of the study is to test, if patients suffering from Endometriosis show changes in their brain function, when being treated with SART Systemic Autoregulation Therapy, a complex intervention consisting of interventions from Traditional Chinese Medicine TCM and Western Hypnotherapy. Functional and structural brain changes are assessed using Magnetic Resonance Imaging data which are analyzed by means of voxel-based morphometry VBM, connectivity and perfusion analysis. A third outcome measure are changes of patients heart rate variability, indicating the activity of their autonomic nervous system.
