Abstract
BACKGROUND: As a common neurological movement disorder, restless leg syndrome (RLS) is often seen in patients with multiple sclerosis (MS). However, the relationship between RLS and MS is still unclear. This case-control study aimed to measure RLS prevalence and uncover its association with MS, as well as to identify possible associated risk factors. METHODS: Six hundred and ninety-five patients were randomly selected from a cohort of patients with MS at the Neurology Department of our hospital, and a group of age- and sex-matched healthy controls (n = 603) was enrolled from the general population. Using a face-to-face interview questionnaire, we collected data on RLS incidence in participants with or without MS. We further assessed sleep quality in all the participants. RESULTS: We found there to be a significantly higher prevalence of RLS among patients with MS compared to healthy controls (odds ratio [OR], 3.8; P < 0.001). Risk factors such as an older MS age at onset and a longer MS duration were significantly associated with the presence of RLS. Furthermore, patients with both MS and RLS were more likely to suffer from sleep complaints compared to patients with MS without RLS. CONCLUSIONS: RLS was significantly associated with MS and was found to have a significant impact on sleep quality, particularly in patients with MS.
