Research Abstract |
Diffusion tensor imaging (DTI) was conducted in 13 treatment-resistant, 12 nontreatment-resistant, and 19 drug-naive patients with major depression. As compared with normal control subjects, a voxel-based analysis revealed significant decrease in fractional anisotropy (FA) in the right frontal white matter in the treatment-resistant patients. Histogram analysis demonstrated significant decrease in peak position of FA histogram of the drug-naive patients. No significant correlation was observed between the FA abnormality and clinical severity as assessed by HDRS, GAF, and MADRS.
