RESUMEN

Objective · To observe the changes of cerebral gray matter pre- and post-treatment with short term drugs in patients with schizophrenia. Methods · T1-weighted brain MRIs were obtained on a 3T scanner in 21 controls and 27 subjects with schizophrenia who were not given antipsychotic medication. The controls and 21 schizophrenia patients received the second scan after 8 weeks of antipsychotic treatment. Voxel-based morphometry (VBM) were used to investigate the differences in gray matter (GM), mainly about the regional GM volumes. Results · GM volumes were significantly smaller in the patient group than those of healthy controls in left cerebellum posterior lobe , left and right parahippocampalgyrus, left middle temporal gyrus(P=0.000, voxels>50). GM volumes extensively decreased after 8 weeks of antipsychotic-treatment compared with pre-treatment in the superior, middle, and inferior temporal gyri, superior,middle and inferior frontal gyri, parahippocampa gyri, cingulate gyri, right supramarginal gyrus, right cerebellum posterior lobe, and right lingual gyrus(P=0.000, voxels>50). Conclusion · Short term antipsychotic treatment (8 weeks) may have adverse effects on the gray matter of patients with acute schizophrenia by reducing the volume of gray matter.
