Restless Legs Syndrome (RLS) is a sensory-motor neurological disorder characterized by an irresistible urge to move the legs. Persistent difficulties with all phases of sleep are common in patients whose RLS symptoms are resolved with treatment. Multiple potential causes for treatment-refractory sleep disturbance exist, including activating effects of dopamine agonists (which are first-line RLS treatments), conditioned insomnia and poor sleep habits as a result of chronic RLS-related sleep disturbance, and comorbid medical and psychiatric illness. Suvorexant provides an important therapeutic option to treat insomnia in the context of RLS. It has demonstrated long-term efficacy, particularly in shortening the duration of nocturnal awakenings and increasing total sleep time. Similarly, it has a comparatively benign side effect profile compared to many other agents typically prescribed to treat insomnia. The investigators aim to determine the effect of suvorexant on actigraphically-derived total sleep time, as well as actigraphically-derived wake after sleep onset, Insomnia Severity Index score, subjective sleep endpoints, and RLS symptom severity.
