Abstract

We have investigated shape deformation of the insula to get a viewpoint of how chronic alcohol consumption affects the perisylvian region and compared the deformity pattern between the left and right hemisphere. A landmark-based structural and surface shape analysis of the insula was performed in 20 patients with alcohol dependence and 20 controls matched for age. The shape analysis revealed that the left and right insula follow distinct shape deformation patterns, which resulted in the reduction of left-right asymmetry. The shape deformity was most prominent in the central part of both insula. Our findings indicate that the right and left hemisphere are both affected but shows distinct patterns of deformation in alcohol dependence.
