Sociodemographic and clinical characteristics of the study sample.
Figure 1.
Gray matter volume differences between autogenous and reactive groups.
A. In comparison to patients with autogenous obsessions, patients with reactive obsessions showed a larger volume in the region of the right Rolandic operculum. Color bar represents t value. L indicates left hemisphere. B. Box-plot depicting adjusted GM volume (in imaging units equivalent to volumetric units) corresponding to peak coordinate of the Rolandic operculum in autogenous, reactive and control groups.

Regions with significant GM volume alterations characterizing the OCD subgroups.
Figure 2.
Gray matter volume differences between reactive group and healthy controls.
A. In comparison to healthy subjects, reactive OCD patients showed a larger caudal putamen (bilaterally). Color bar represents t value. L indicates left hemisphere. B. Box-plot depicting adjusted GM volume (in imaging units equivalent to volumetric units) corresponding to peak coordinate in the left caudal putamen (above) and the right caudal putamen (below) in autogenous, reactive and control groups.
Figure 3.
Gray matter volume differences between autogenous group and healthy controls.
A. In comparison to healthy controls, autogenous OCD patients showed a smaller GM volume in the left anterior temporal lobe. Color bar represents t value. L indicates left hemisphere. B. Box-plot depicting adjusted GM volume (in imaging units equivalent to volumetric units) corresponding to peak coordinate in the left anterior temporal lobe in autogenous, reactive and control groups.
