Serotonin is once again likely to play an important role in mediating both the symptoms of this disorder, and its robust response to treatment with SSRIs.

Anterior cingulate, which is involved in performance monitoring (McDonald et al, 2000), may play a crucial role in a number of anxiety disorders, including SP. In addition, imaging studies that have pooled or compared findings across different anxiety disorders suggest the importance of increased activation of inferior cortex in mediating anxiety symptoms (Rauch et al, 1997b).
