Some people think that restless legs syndrome (RLS) is a joke, not an actual medical condition.
Not so, says Dr. Stephen Barczi, a physician who specializes in sleep disorders at the University of Wisconsin- Madison.
“Restless legs syndrome is a real neurologic and sleeprelated condition,” he says, adding that 10 to 12 percent of Americans suff er from the puzzling disorder.
People who have it often can’t sit still or enjoy a full night’s sleep — because their legs are constantly tingling, twitching and needing to move.
Physicians believe RLS is associated with a deficiency of iron in the blood or dopamine in the brain. It can also appear with conditions ranging from diabetes to pregnancy.
