What micronutrient deficiencies should be considered in distinct neurological disorders?

The expanding understanding of the biochemical and physiologic role of micronutrients, commonly referred to as vitamins and minerals, is driving the identification of their consequences in both deficiency and toxicity. Neural tissue is quite sensitive to physiologic changes, and as such, micronutrient deficiencies can have significant and profound effects on the functioning of both the central and peripheral nervous systems. Understanding which micronutrients can affect the nervous system can aid physician identification of these neurological symptoms and signs, leading to diagnostic testing and appropriate therapy.
