General anxiety disorder (GAD) affects cognitive function in combination with the process and regulation of emotion. In general, patients with GAD have more difficulty in identifying their own emotions and understanding of emotional experience as compared with healthy controls. Recent studies have investigated the neural activation associated with cognitive processing in response to visual stimulation with facial images in health controls and patients with GAD, and revealed that the cognitive function of facial expression in patients with GAD was impaired.
