Restless leg syndrome not a laughing matter

DEAR DR. ROACH: Why do people snicker when I tell them I have RLS? They wouldn’t laugh if they knew the amount of sleep deprivation I have endured during the 20 years it took to correctly diagnose it. I think if it hadn’t been for Sinemet (levodopa and carbidopa), a Parkinson’s drug, I would have gone mad long ago. Has anyone discovered what causes it? —G.S.G.

ANSWER: Restless leg syndrome causes an urge to move the legs (and sometimes arms), which is worse at nighttime and is relieved by movement. It is usually accompanied by unpleasant sensations in the legs. When accompanied by sleep deprivation, as yours has been, it is also called periodic limb movement disorder.

The cause is known only in a minority of cases. About 40 percent of cases seem to run in families, and several genetic factors have been identified. Iron deficiency sometimes is associated with RLS, and replacement of the iron can improve symptoms. Moderate exercise, leg massage and heat (say, a warm bath before bed) are some nondrug ways of improving symptoms. Levodopa/carbidopa is an effective treatment; pramipexole (Mirapex) and ropinirole (Requip) also are effective for many people. There are other alternatives as well. An expert in the condition, usually a neurologist, is essential for severe cases.

I think the name “restless leg syndrome” may be part of why people don’t take this condition as seriously as it deserves. After all, legs are supposed to move, and being “restless” doesn’t sound so bad — but as you know, it’s a lot more than that. For this reason, the new name, Willis-Ekbom disease, is preferred by some.

Great information about this condition is available at RLS.org.

  • Allergies are the real midlife crisis

    One of the biggest mysteries is why the disease comes and goes, and then comes and goes again. People tend to experience intense allergies between the ages of 5 and 16, then get a couple of decades off before the symptoms return in the 30s, only to diminish around retirement age.

  • 4 years after spill, questions on long-term health

    When a BP oil well began gushing crude into the Gulf of Mexico four years ago, fisherman George Barisich used his boat to help clean up the millions of gallons that spewed in what would become the worst offshore spill in U.S. history.

    Like so many Gulf Coast residents who pitched in after the April 20, 2010, explosion of the Deepwater Horizon rig, Barisich was motivated by a desire to help and a need to make money — the oil had destroyed his livelihood.
