Ataide MF, da Cunha-Correia C, Petribú KCL, et al. - In patients with myasthenia gravis (MG), researchers conducted this cross-sectional study to characterize the prevalence of restless legs syndrome (RLS) and its severity and influence on the quality of life (QOL). This investigation was carried out from May to June 2016 in Recife, Brazil. Using a sociodemographic questionnaire, MG QOL questionnaire-15, and The RLS Rating Scale, a sample of 42 individuals were interviewed. Investigators found that in 47.6% of patients RLS was present; of these, 40.5% met moderate to severe RLS criteria. The quality-of-life scores were worse on average among patients with RSL. There was no connection of RLS with MG duration, use of immunosuppressant, or clinical conditions that could mimic the occurrence of RLS. The authors concluded that RLS is a prevalent condition in MG patients and can be sufficiently severe to adversely affect QOL.
