A review of the research literature on selenium and selenoprotein function in brain disorders reveals that selenium deficiency is associated with impaired cognitive function and impaired motor function [Pillai].
It is interesting to note that selenium concentrations are preferentially maintained in the brain even when the selenium concentrations in the blood circulation, in the liver, and in the skeletal tissues are depleted [Pillai].
Selenium supplementation may help to reduce the progression of the pathology of neurodegenerative diseases: Alzheimer’s, Huntington’s, and Parkinson’s [Pillai].
