Relationship between parathyroid hormone and magnesium in sera of the dementia patients

Abstract

The dementia patients with central nervous or neuro-cerebro vascular disorders seemed to be decreased serum Mg due to abnormal Mg uptake in diet. An increment of PTH level was paralleled with a rise of serum Mg and hypomagnesemic group was shown to have a lower PTH level in these patients. Our results suggested that secondary hypoparathyroidism was likely to be induced by normo-calcemic hypomagnesemia.
