Wali S, et al. - Researchers studied the correlation between restless legs syndrome (RLS) and vitamin D deficiency in 78 patients with RLS, based on the International RLS Study Group (IRLSSG) diagnostic criteria, compared to 123 controls. RLS severity was evaluated via the IRLSSG symptom severity rating scale. It was determined that 59 patients with RLS (75.6%) and 52 controls (42.3%) had vitamin D deficiency. Findings illustrated a link between vitamin D deficiency and RLS. Therefore, vitamin D deficiency ought to be taken into account for the management of RLS.
