Panic Disorder With Agoraphobia Clinical Trial
Official title:
Effect of Cognitive-behavior Therapy on Panic Symptomatology and the Activation of the Brain's Fear Network to Panic-related Body Symptoms in Patients With Panic Disorder
The present study aims to investigate a potential mechanism of successful CBT for panic disorder, i.e., the reduction of excessive anxious apprehension and fear responses to panic-related body symptoms in the context of CBT treatment. In the present non-randomized interventional study, effects of cognitive behavior therapy on reported symptoms and fear responses to panic-related body symptoms are investigated. It is expected that symptom improvement during CBT is associated with a decrease in the activation of the brain's fear network to panic-related body symptoms.
Changes in fear responses to body symptoms in the course of CBT are investigated in patients with PD by applying a highly standardized hyperventilation task (provoking panic-related body symptoms) prior to and after a manualized CBT or a waiting period. Activation of the brain's fear network (defensive activation) is indexed by the potentiation of the startle eyeblink response. ;
