The purpose of this study was to combine two automated methods of magnetic resonance imaging (MRI) structural analysis in order to identify structural changes in patients born in Argentina with idiopathic generalized epilepsy (IGE) compared to a healthy adult control group. Twenty-eight patients with IGE and 26 controls with no significant demographic differences were included. The analysis of the brain structures was conducted with two automated methods of magnetic resonance image analysis: voxelbased morphometry and FSL-integrated registration and segmentation toolbox (FSL-FIRST). FSL showed volume decrease in both thalamus in patients with IGE compared to the control group (left: 8092 mm3 control group vs. 7424 mm3 IGE, p = 0.0015; right: 7951 mm3 control group vs. 7247 mm3 IGE, p = 0.0016). A reduction in the volume of both caudate nuclei was also seen (left: 3612 mm3 control group vs. 3376 mm3 IGE, p = 0.01; right: 3683 mm3 control group vs. 3459 mm3 IGE, p = 0.04). Voxel-based-morphometry showed a volume decrease in both caudate nuclei in patients with IGE compared to the control group. The other cerebral structures analyzed did not show significant differences between the groups. In conclusion, this study shows the reduction in volume in the subcortical, thalamic, and caudate nuclei structures in patients with IGE in comparison to control group. This study conducted in our country delves into the analysis of brain structural changes in patients with EGI compared to healthy subjects.
