The amygdala and anxiety after epilepsy surgery.

The relationship between amygdalar volume and anxiety after epilepsy surgery was explored. Participants comprised patients who underwent mesial temporal (n=26) or non-mesial temporal resections (n=16) and 41 neurologically normal controls. Anxiety was prospectively measured preoperatively and for the first 12 months postoperatively using criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition.
