Brain volume changes after just nine weeks of cognitive behavioral therapy:
After just nine weeks of internet-delivered cognitive behavioural therapy, the brain of patients suffering from social anxiety disorder changes in volume. Anxiety is reduced, and parts of the patientsâ€™ brains decrease in both volume and activity.
This study could help us develop more effective therapies for one of the most common problems in mental health.
We have known for many years that the brain is remarkably adaptable. For instance, previous studies have shown that juggling and video games affect brain volume. However many questions about how the brain adapts remain unanswered.
The researchers found that in patients with social anxiety disorder (SAD), brain volume and activity in the amygdala decrease as a result of internet-based cognitive behavioral therapy (ICBT). The results are presented inÂ Translational Psychiatry, a Nature publication.
â€śThe greater the improvement we saw in the patients, the smaller the size of their amygdalae. The study also suggests that the reduction in volume drives the reduction in brain activityâ€ť, says doctoral student Kristoffer NT MĂĄnsson, who led the study together with LinkĂ¶ping colleague Gerhard Andersson and researchers from the Karolinska Institutet, Uppsala University, UmeĂĄ University and Stockholm University.
