Gray and white matter brain changes have been found in schizophrenia but the anatomical organizing process underlying these changes remains unknown. We aimed to identify gray and white matter volumetric changes in a group of patients with schizophrenia and to quantify the distribution of white matter tract changes using a novel approach which applied three complementary analyses to diffusion imaging data. 21 patients with schizophrenia and 21 matched control subjects underwent brain magnetic resonance imaging. Gray and white matter volume differences were investigated using Voxel-based Morphometry (VBM). White matter diffusion changes were located using Tract Based Spatial Statistics (TBSS) and quantified within a standard atlas. Tracts where significant regional differences were located were examined using fiber tractography. No significant differences in gray or white matter volumetry were found between the two groups. Using TBSS the schizophrenia group showed significantly lower fractional anisotropy (FA) compared to the controls in regions (false discovery rate <0.05) including the genu, body and splenium of the corpus callosum and the left anterior limb of the internal capsule (ALIC). Using fiber tractography, FA was significantly lower in schizophrenia in the corpus callosum genu (p = 0.003). In schizophrenia, white matter diffusion deficits are prominent in medial frontal regions. These changes are consistent with the results of previous studies which have detected white matter changes in these areas. The pathology of schizophrenia may preferentially affect the prefrontal-thalamic white matter circuits traversing these regions.

The description of Medical Student Syndrome is based on the assumption that inexperienced medical students are prone to develop a pathological fear of medical conditions they are taught about. The aim of this study is to examine the sample of students (medical and non-medical) in order to assess and compare their level of hypochondriacal attitudes and health-related anxiety. We also examined other factors which might have had an influence on hypochondria and nosophobia attitudes among students. Methods: The study was conducted in two groups of students: 313 medical students at the Medical University of Silesia and 293 students at non-medical universities in Katowice, Poland. The study used the medical student syndrome self-explanatory questionnaire constructed for the study, taking into account the specificity of the group and the research problem. The research questionnaire was completed in an online survey by 606 students. Results: The results of the study showed that medical students obtained the same scores on a nosophobic scale as the non-medical students (p = 0.5). The analysis of hypochondriacal behavior showed significantly higher results in the non-medical student group (p = 0.02). In the entire study group, females and participants with mental disorders obtained higher scores in relation to nosophobia. Symptoms of depression and anxiety were more common in the group of medical students. Conclusions: Medical studies are not a risk factor for the occurrence of health anxiety and hypochondrial attitudes. Such factors are female gender and having a mental illness.
