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

Semin Arthritis RheumPublished Cross-sectional study

Authors' conclusion

DTI findings might potentially serve as a neuroimaging marker to predict the extent of neurocognitive impairment and disease severity associated with central nervous system involvement in BS.

Study context

Population
Patients with Neuro-Behcet's syndrome and Behcet's syndrome without neurological manifestations, and healthy controls
Participants
34 / 32 / 33
Exposure
Neuro-Behcet's syndrome vs Behcet's syndrome without neurological manifestations vs healthy controls
  • Neuro-Behcet's syndrome (NBS)n = 34
  • Behcet's syndrome (BS)n = 32
  • Healthy controlsn = 33reference
Outcome
Microstructural integrity of brain white matter tracts on diffusion tensor imaging (DTI)
Methodological detailsdiffusion tensor imaging, tract-based spatial statistics, automated probabilistic tractography
  • Diffusion tensor imaging
  • Tract-based spatial statistics
  • Automated probabilistic tractography

Main finding

As reported in the abstract

White matter microstructural integrity (DTI)
  • NBS: decreased fractional anisotropy and increased radial, mean and axial diffusivity in supratentorial and infratentorial white matter, indicating widespread loss of microstructural integrity
  • BS without neurological manifestations: loss of integrity also observed, to a lesser extent

Observational data: associations, not effects.

Further findings

Association of white matter tracts with cognition and disease severity in NBS

Certain tracts, including cingulum bundle, associated with poor cognitive performance across multiple domains and disease severity
