White matter diffusion abnormalities in migraine and medication overuse headache: A 1.5-T tract-based spatial statistics study

Our 1.5-T DTI study demonstrated significantly lower fractional anisotropy in the white matter in the MoA with medication overuse headache and MwA without medication overuse headache groups, suggesting that fractional anisotropy abnormalities may be useful biomarkers in headache patients.
