Vascular risk and low serum B12 predict white matter lesions in patients with major depression

Background patients with depression have been shown to have a greater incidence of vascular risk factors and structural brain changes, any association with dietary co-factors is unclear. s seven patients with major depression (mean age=52.8 years, SD=12.6) and 21 healthy volunteers (mean age=54.7 years, SD=9.1) underwent high-resolution magnetic resonance imaging scanning. T2-weighted films were scored for deep white matter (DWM), periventricular (PV), and subcortical (SC) hyperintensities. s was no difference in lesion severity between patients and control subjects. After controlling for age, vitamin B12 levels were predictive of DWM lesions in patients. DWM and SC lesions were associated with histories of hypertension and diabetes. tions tively small sample of patients were recruited from specialist services and the findings may not represent those observed in larger or community-based cohorts. sions ients with major depression, vitamin B12 levels and histories of hypertension and/or diabetes are predictive of white matter lesions.
