Magnesium concentration in brains from multiple sclerosis patients. Acta Neurol Scand. 1990 Mar;81(3):197-200.

In a 1990 paper published by researchers from the Wakayama Medical College, Japan, magnesium (Mg) concentrations were studied in the brains of 4 patients with definite multiple sclerosis (MS) and 5 controls. The central nervous system tissues and the visceral organs, except for spleen, of MS patients showed significantly lower magnesium values than that seen in control cases. http://www.ncbi.nlm.nih.gov/pubmed/2353567?dopt=Abstract
