An often undiagnosed condition that is thought to affect up to 10% of the population is the subject of new research.

Anybody who suffers from restless legs syndrome (RLS) is bothered by unpleasant sensations in the legs at night, the only remedy for which is moving. It has always been completely unclear what triggers this condition.

The findings will be published July 18 in the online edition of the New England Journal of Medicine and will appear in an upcoming printed edition of the journal.

People with restless legs syndrome (RLS), especially the elderly, may be at an increased risk of developing cardiovascular disease, according to a study published in the April 10, 2007, issue of Neurology®, the scientific journal of the American Academy of Neurology.
