Abstract
In the article “Deep brain stimulation improves restless legs syndrome in patients with Parkinson disease,” Dr. Klepitskaya et al. reported sustained improvement in symptoms of restless legs syndrome (RLS) over 2 years in 22 patients with Parkinson disease (PD) who underwent subthalamic nucleus (STN) deep brain stimulation (DBS), despite a decrease in dopaminergic treatment. Drs. Marques et al. point out that the article misinterpreted the results of their previous study, which showed an emergence of RLS in patients with PD with a higher dose of dopamine agonists and a lower decrease in dopaminergic treatment after STN DBS. They discuss the paradoxical findings of STN DBS apparently improving preexisting RLS but causing emergence of RLS in some patients with PD and the need for further research. In response, Dr. Klepitskaya acknowledges these comments including the misinterpretation. A correction appears on page 871.
