Die Expositionstherapie ist die effektivste Methode zur Behandlung von Angststörungen, insbesondere spezifischer Phobien. Doch was tun, wenn die Vorstellungskraft nicht reicht und für Konfrontationen mit angstauslösenden Situationen der Aufwand zu groß ist? Mit Virtual Reality eröffnen sich völlig neue Chancen. Computer-generierte realitätsnahe Spinnen, Höhen, Flugreisen oder soziale Kontakte erlauben, die Therapie unkompliziert unter kontrollierten Bedingungen und mit graduellen Steigerungen der Reizintensität durchzuführen. In diesem Fachbuch werden theoretische Grundlagen, wissenschaftliche Studien und erprobte Strategien für den Einsatz von VR in der Behandlung von Ängsten und Phobien kompakt, fundiert und praxisnah beschrieben. Sie erhalten wertvolle Tipps, wie auch Sie diese Technologie für Ihre therapeutische Arbeit nutzen.

Abstract: Preclinical studies point to a pivotal role of the orexin 1 (OX1) receptor in arousal and fear learning and therefore suggest the HCRTR1 gene as a prime candidate in panic disorder (PD) with/without agoraphobia (AG), PD/AG treatment response, and PD/AG-related intermediate phenotypes. Here, a multilevel approach was applied to test the non-synonymous HCRTR1 C/T Ile408Val gene variant (rs2271933) for association with PD/AG in two independent case-control samples (total n = 613 cases, 1839 healthy subjects), as an outcome predictor of a six-weeks exposure-based cognitive behavioral therapy (CBT) in PD/AG patients (n = 189), as well as with respect to agoraphobic cognitions (ACQ) (n = 483 patients, n = 2382 healthy subjects), fMRI alerting network activation in healthy subjects (n = 94), and a behavioral avoidance task in PD/AG pre- and post-CBT (n = 271). The HCRTR1 rs2271933 T allele was associated with PD/AG in both samples independently, and in their meta-analysis (p = 4.2 × 10−7), particularly in the female subsample (p = 9.8 × 10−9). T allele carriers displayed a significantly poorer CBT outcome (e.g., Hamilton anxiety rating scale: p = 7.5 × 10−4). The T allele count was linked to higher ACQ sores in PD/AG and healthy subjects, decreased inferior frontal gyrus and increased locus coeruleus activation in the alerting network. Finally, the T allele count was associated with increased pre-CBT exposure avoidance and autonomic arousal as well as decreased post-CBT improvement. In sum, the present results provide converging evidence for an involvement of HCRTR1 gene variation in the etiology of PD/AG and PD/AG-related traits as well as treatment response to CBT, supporting future therapeutic approaches targeting the orexin-related arousal system
