Psychotherapy normalizes the brain in social phobia

06.02.2017

Psychotherapy is a central treatment for social anxiety disorder. Due to this treatment, changes in key brain structures involved in emotion processing and regulation are normalized, as researchers from the University of Zurich, Zurich University Hospital and the University Hospital of Psychiatry Zurich demonstrate in a new study.

Anxiety in social situations is not a rare problem: Around one in ten people are affected by social anxiety disorder during their lifetime. Social anxiety disorder is diagnosed if fears and anxiety in social situations significantly impair everyday life and cause intense suffering.

Talking in front of a larger group can be one typical feared situation. A study conducted by researchers from the University of Zurich, Zurich University Hospital and the University Hospital of Psychiatry Zurich now reveals that the successful treatment of an anxiety disorder alters key brain structures that are involved in processing and regulating emotions.


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.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
