Neuropsychological Comparison Between Patients with Social Anxiety and Healthy Controls: Weak Central Coherence and Visual Scanning Deficit.

Abstract

IntroductionAlthough deficits in neuropsychological functioning have been reported in social anxiety disorder (SAD), studies focusing on neuropsychological dysfunction in SAD are limited, and the evidence is still lacking. The purpose of this study was to examine the deficits in neuropsychological functioning in patients with SAD by comparing SAD patients and a healthy control (HC) group.Materials and MethodsA total of 72 participants (20 in the SAD group and 52 in the HC group) were assessed with neuropsychological tests, consisting of the Rey Complex Figure Test (RCFT) to measure central coherence and the Trail Making Test A and B (TMT-A; TMT-B) to measure visual scanning and executive functioning.ResultsAnalysis of covariance with depressive symptoms as a covariate revealed that central coherence (RCFT) and visual scanning (TMT-A) were significantly lower in the SAD group than in the HC group. No difference was found in executive functioning (TMT-B) when the effect of visual scanning was considered.DiscussionOur findings suggest that SAD patients have weak central coherence and deficits in visual scanning compared to healthy controls. The clinical implications of these neuropsychological functioning deficits in SAD patients are discussed.
