Patients with social anxiety disorder usually showed reduced activation in occipital clusters that are similar to high-order visual cortical regions while completing tasks that require emotion regulation on images of angry faces. An essential objective of cognitive behavioral therapy is to improve emotion regulation in patients who suffer from social anxiety disorder. Therefore, the researchers theorize that cognitive behavioral therapy was mainly successful in patients with greater emotion regulation abilities, which was correlated with having a more intense response in visual regions to angry faces. This finding shows that there are variations between social anxiety patients and that they may need different treatments based on their brain activations.
