A new study has revealed that Restless Legs Syndrome (RLS) may be a possible biomarker for other underlying disease.

The study done by a nationally-recognized sleep expert found that patients with RLS have a higher mortality rate and are prone to cardiovascular diseases and hypertension.

Boston Medical Center neurologist Sanford H. Auerbach said that men with RLS were more likely to be diagnosed with lung disease, endocrine disease, diseases of nutrition and metabolism and immune system problems.

The study was published in Neurology the medical journal of the American Academy of Neurology.
