Overview
Brief Summary
Evaluation of longitudinal treatment effects applying an intensive psychotherapeutic intervention for inpatients (age of participants: 6-13 years) with a multi-method-approach to address the complex nature of severe childhood trauma. (Chronic Post-Traumatic Stress Disorder)
Detailed Description
Severe adversity and trauma in early childhood have been associated with a highly increased risk for a variety of psychiatric disorders, lasting into adulthood. This increased risk is accompanied by a set of biological changes ranging from changes in cortical thickness to endocrinological changes. At a behavioral level, children with complex PTSD (developmental trauma disorder) show severe and long-lasting negative effects. Such children exhibit a wide range of symptoms: affect dysregulation, attention difficulties, impairment in interpersonal relationships, aggressive and dissociative behaviour, disturbances of cognition. Corresponding alterations in neural networking and brain development are well studied. Although evidence-based treatment approaches for children with non-complex PTSD exist, complex-traumatized children have no well-evaluated treatments. Furthermore, early intervention can prevent the chronification and exacerbation of symptoms and promote social adaptation and participation.The following topics will be addressed: (1) brain development (Multimodal MRI (mMRI) including anatomical (T1-MPRAGE, T2-FLAIR, DTI-Diffusion Tensor Imaging) and functional MRI measurements (resting-state functional MRI, task fMRI (presenting affective pictures according to the International Affective Picture System, IAPS), EEG); (2) alterations in neuroendocrinological systems involved in stress regulation (Cortisol, Oxytocin, Vasopressin); (3) behavioral symptoms; (4) cognitive functioning; (5) attachment representations of children and their primary caregivers;

Outcomes
Primary Outcomes
Structural MRI (T1w, T2w, DTI)
Time Frame: longitudinal (4 measurements, t0: at least 3 month before treatment, t1: at admission to treatment, t2: at discharge (average of 8 month), t3: 6 month post treatment)
All structural images will be acquired in a 3 Tesla MR system using a 20- channel head-coil (Siemens, Erlangen). Data post-processing will be performed with lab-internal scripts developed for a multi-core cluster. For structural analyses of T1w, T2w and DTI data, freesurfer,FSL and workbench will be used. T1w and T2w data will be volumetrically analyzed and the results will be reported in mm3. DTI data will be processed using tbss-FSL and probtrackX-FSL. DTI will be quantified in regard of the number of white matter fiber bundles within regions-of-interest (ROIs) and from-ROI-to-ROI. The Dosenbach atlas (Dosenbach et al. 2010) and the multimodal Brainetome atlas (Fan et al. 2016) will be used for all structural analyses. It is an explorative study that follows a whole-brain approach. Changes in emotion-processing and trauma-associated brain regions such as the hippocampus,the amygdala,the orbitofrontal cortex and the insula are assumed
Resting state functional MRI connectivity (rsfcMRI)
Time Frame: longitudinal (4 measurements, t0: at least 3 month before treatment, t1: at admission to treatment, t2: at discharge (average of 8 month), t3: 6 month post treatment)
EPI-sequence: fMRI will be carried out at 3 Tesla (Siemens) scanner using a 20- channel head-coil. For functional imaging, an EPI sequence with the following parameters will be used: repetition time (TR),2000 ms; echo time (TE),30 ms; flip angle (FA), 80°; spatial resolution, 3 × 3 × 3 mm3; imaging matrix, 64 × 64; field-of-view (FoV), 192 × 192 mm2; number of slices: 36; number of volumes: 200. Data post-processing will be performed with lab-internal scripts developed for a multicore cluster. For rsfcMRI analyses of freesurfer,FSL,AFNI and workbench will be used. rsfcMRI will be quantified as number of significant activated voxels (spatial extent) and connectivity strength (z-scores).Networks of interest (ICA-based): Salience network, Default Mode Network. Regions of interest (seed-based): hippocampus, the amygdala, the orbitofrontal cortex and the insula.In addition, a RS-EEG with 19 scalp electrodes is used to complement rsfcMRI,which is cortically evaluated using Brainstorm.
Task-based fMRI using the International affective picture system (IAPS)
Time Frame: longitudinal (4 measurements, t0: at least 3 month before treatment, t1: at admission to treatment, t2: at discharge (average of 8 month), t3: 6 month post treatment)
For the task-based fMRI the same EPI sequence will be used as for the resting state (see outcome 2). The number of volumes: 180. Three different sets of each 45 (15 neutral, 15 negative, 15 positive rated pictures) pictures were created and randomly displayed during the scanning procedure and also afterward to control for personal affective valence and arousal with Self-Assessment Manikin (SAM). Data post-processing will be performed with FSL-FEAT using a block-design. Regions of interest follow the previous structural and rsfcMRI analyses ROIs: hippocampus, amygdala, orbitofrontal cortex and the insula.
Secondary Outcomes
- Alterations in neuroendocrinological systems involved in stress regulation(longitudinal (4 measurements, t0: at least 3 month before treatment, t1: at admission to treatment, t2: at discharge (average of 8 month), t3: 6 month post treatment))
- Alterations in neuroendocrinological systems involved in stress regulation 2(longitudinal (4 measurements, t0: at least 3 month before treatment, t1: at admission to treatment, t2: at discharge (average of 8 month), t3: 6 month post treatment))
- Alterations in neuroendocrinological systems involved in stress regulation 3(longitudinal (4 measurements, t0: at least 3 month before treatment, t1: at admission to treatment, t2: at discharge (average of 8 month), t3: 6 month post treatment))
