Human imaging studies have implicated structural and functional abnormalities in patients with bipolar disorder. In this study we examined the differences in diffusion tensor imaging (DTI) data between bipolar patients and healthy control subjects using the methodology of Track-Based Spatial Statistics and our newly developed SPM's Toolbox. We found that bipolar disorder patients had significantly lower fractional anisotropy values within the cingulate gyrus when compared to control subjects. Our findings suggest that DTI techniques can highlight microstructural abnormalities in the brain, not evident on conventional MRI, which may be associated with the neuropathology of this disorder.
