Brain white matter microstructural alterations in Behcet's syndrome correlate with cognitive impairment and disease severity: a diffusion tensor imaging study

To evaluate the microstructural integrity of brain white matter tracts in patients with Neuro-Behcet's syndrome (NBS) and Behcet's syndrome (BS) without neurological manifestations using diffusion tensor imaging (DTI) and to investigate potential utility of DTI as a surrogate biomarker of neurocognitive functioning and disease severity.
