Objective: People who have experienced childhood abuse are more likely to experience frequent or generalized anxiety or panic disorder (PD). Although previous studies have used magnetic resonance imaging (MRI) to demonstrate structural abnormalities of brain in subjects with PD, there are no study about the brain white matter (WM) connectivity differences between PD with and without early sexual abuse. The objective of this study is to compare the brain WM connectivity between PD with and without early sexual abuse history. Design and Method: Twelve right-handed patients with PD [12 women; 35.91±10.29 (mean±SD) age] who met the diagnostic criteria in Structured Clinical Interview for DSM-IV were examined by means of MRI at 3 Tesla. We divided the patients with PD into two groups with and without early sexual abuse to compare the WM connectivity. Panic Disorder Severity Scale (PDSS), Beck Depression Inventory (BDI) and Anxiety Sensitivity Index-Revised (ASI-R) were administered in PD patients. Results: Tract-based spatial statistics showed that fractional anisotropy (FA) values in PD with sexual abuse history were significantly higher than PD without abuse in the right internal capsule, superior corona radiata, sagittal stratum, fornix. The scores of PDSS, BDI, ASI-R were significantly correlated in the above-mentioned WM regions. Conclusions: This preliminary study suggests that early sexual abuse could influence the connectivity among emotion related limbic structures in PD.
