Parahippocampal Gray Matter Density in Panic Disorder: A Voxel-Based Morphometric Study

Guillem Massana, M.D., Ph.D., Josep Maria Serra-Grabulosa, Ph.D., Pilar Salgado-Pineda, M.S., Cristòbal Gastó, M.D., Ph.D., Carme Junqué, Ph.D., Joan Massana, M.D., Ph.D., and José María Mercader, M.D., Ph.D.

OBJECTIVE: The authors examined possible cerebral gray matter abnormalities in patients with panic disorder. METHOD: Gray matter concentration in 18 panic disorder outpatients and 18 healthy subjects was compared by using a voxel-based morphometry approach. RESULTS: Gray matter density of the left parahippocampal gyrus was significantly lower in patients with panic disorder compared with healthy subjects. CONCLUSIONS: This result provides further support for the involvement of the parahippocampal area in the pathophysiology of panic disorder.
