Each 10 nmol/L increase in vitamin D is associated with a small decrease in white matter hyperintensities, suggesting brain protection.

“Neuroimaging studies correlate higher serum vitamin D with fewer white matter hyperintensities—markers of structural brain damage predictive of dementia.”

“For every 10 nanomal per liter increase in vitamin D, there was a small decrease in”

“But then you can go a step further and you can look at other studies that have shown vitamin D deficiency actually accelerates brain aging. So there have been studies that have shown that have looked by fMRI at what's called white matter hyperintensities. So these kind of show up of as little white hypers spots if you're looking at a MRI image of the brain and it's really a marker of damage to the white matter in the brain.”

“for every 10 nanimals per liter increase in vitamin D levels there was a decrease in the damage to their to the white matter part of the brain”

“vitamin D deficiency causes this what's called white matter hyperintensities. It's this type of damage and white matter that shows up as like a white spot on an fMRI”
