Vitamin B-12 deficiency may leads to microstructural changes in brain white matter. The purpose of this study was to determine the change in DTI metrics in brain white matter and to find out its association with cognitive function among patients with vitamin B-12 deficiency. In this study, we included 8 patients with vitamin B-12 deficiency and 9 healthy controls. ATR and PTR fibers showed significant reduction in FA values with abnormal cognitive function in these patients. These changes in ATR and PTR in patients with vitamin B12 deficiency with normal appearing conventional MRI suggest these findings may be used as image biomarkers of B12 deficiency in future.
