Abstract
Understanding the biological basis of social anxiety disorder (SAD), one of the most disabling of the anxiety disorders, will allow for novel treatment strategies to be developed. Here, we show that gut microbiota may be such a target. Mice ...Social anxiety disorder (SAD) is a crippling psychiatric disorder characterized by intense fear or anxiety in social situations and their avoidance. However, the underlying biology of SAD is unclear and better treatments are needed. Recently, the gut ...
