Cognitive behavioral therapy pivotal
In patients suffering from social anxiety disorder, regulation of excessive anxiety by frontal and lateral brain areas is impaired. Strategies aimed at regulating emotions should restore the balance between cortical and subcortical brain areas. These strategies are practised in cognitive behavioral therapy (CBT) which is a central therapy for social anxiety disorder. The study from Zurich investigated structural brain changes in patients suffering from social anxiety disorder after a specific ten-week course of CBT. Using magnetic resonance imaging the participants’ brains were examined before and after CBT.
Changes in the brain normalized
“We were able to show that structural changes occur in brain areas linked to self control and emotion regulation,” says Annette Brühl, head physician at the Center for Depression, Anxiety Disorders and Psychotherapy at the University Hospital of Psychiatry Zurich (PUK). The more successful the treatment, the stronger brain changes. The research group was also able to demonstrate that brain areas involved in processing emotions were more interconnected after the treatment. “Psychotherapy normalizes brain changes associated with social anxiety disorder,” Brühl sums up.

Cognitive behavioral group therapy
In cognitive behavioral group therapy, patients learn and apply new strategies aimed at dealing with social anxiety disorder. Based on specific examples, the group discusses explanatory models and identifies starting points for changes. Through self-observation, role plays or video recordings, alternative viewpoints can be developed.
