Disorders of bone and bone mineral metabolism.

Metabolic bone disorders are very common in the general population and untreated, they can cause a variety of neurologic symptoms. These diseases include osteoporosis, vitamin D deficiency, Paget's disease, and alterations in calcium, phosphorus, and magnesium metabolism. Diagnosis is made through analysis of metabolic bone blood chemistries as well as radiologic studies such as dual energy X-ray absorptiometry (DXA) scans, bone scans, and X-rays. Treatment options have advanced significantly in the past decade for osteoporosis and Paget's disease and mainly include antiresorptive therapy. New recommendations for treatment of primary hyperparathyroidism are discussed as well as therapy for calcium, phosphorus, and mineral disorders.
