| Abstract: | Background and purpose Morphological brain changes related to hypovitaminosis D have been poorly studied. In particular, the age-related decrease in vitamin D concentrations may explain the onset of white matter abnormalities ( WMA) in older adults. Our objectives were (i) to investigate whether there was an association between serum 25-hydroxyvitamin D (25 OHD) concentration and the grade of WMA in older adults and (ii) to determine whether the location of WMA was associated with 25 OHD concentration. Methods One hundred and thirty-three Caucasian older community-dwellers with no clinical hydrocephalus (mean 71.6 ± 5.6 years; 43.6% female) received a blood test and a magnetic resonance imaging scan of the brain. The grades of total, periventricular and deep WMA were scored using semiquantitative visual rating scales from T2-weighted fluid-attenuated inversion recovery images. The association of WMA with as-measured and deseasonalized 25 OHD concentrations was evaluated with the following covariates: age, gender, body mass index, use of anti-vascular drugs, number of comorbidities, impaired mobility, education level, Mini-Mental State Examination score, medial temporal lobe atrophy, serum concentrations of calcium, thyroid-stimulating hormone and vitamin B12, and estimated glomerular filtration rate. Results Both as-measured and deseasonalized serum 25 OHD concentrations were found to be inversely associated with the grade of total WMA (adjusted β = −0.32, P = 0.027), specifically with periventricular WMA (adjusted β = −0.15, P = 0.009) but not with deep WMA (adjusted β = −0.12, P = 0.090). Similarly, participants with 25 OHD concentration <75 nM had on average a 33% higher grade of periventricular WMA than those with 25 OHD ≥75 nM ( P = 0.024). No difference in average grade was found for deep WMA ( P = 0.949). Conclusions Lower serum 25 OHD concentration was associated with higher grade of WMA, particularly periventricular WMA. These findings provide a scientific basis for vitamin D replacement trials. [ABSTRACT FROM AUTHOR] |
