restless leg syndrome: a neglected diagnosis

conclusions the most important factor in diagnosis is physician’s attention and clinical experience with this condition and using irlssg. results two major theories are developed regarding the pathophysiology of rls. the first one concerns central nervous system dopamine imbalance and the second one concerns intracellular iron dysregulation. the most common used pharmacologic agents in treatment of rls are dopamine agonists. other used therapeutic agents include levodopa, alpha-2-delta calcium channel ligands, opioids, anticonvulsants, benzodiazepines, clonidine, iron therapy in low levels of serum ferritin, and nonpharmacologic therapies. evidence acquisition for data extraction, we reviewed pubmed, scopus, google scholar, the cochrane collaboration, and up to date databases with the keywords of restless legs syndrome, sleep disorders, and end-stage renal disease (esrd). the most recent review articles, clinical trials, and cross-sectional studies with large sample sizes that had used international rls study group criteria (irlssg) and had focused on demographic characteristics and renal function were included. this situation has described in primary and secondary forms. the former usually occurs in younger patients and seems to have genetic tendencies and the latter is due to the iron deficiency state, pregnancy, and esrd. context restless legs syndrome (rls) is an irresistible urge to move legs that usually occur during inactivity and at night. this neurologic condition is associated with increased risk of nocturnal hypertension as well as cardiovascular events and affects patient’s sleep, which leads to anxiety, depression, and decreases quality of life. presence of rls in patients on hemodialysis is associated with higher mortality rate. most of the times, patients have indescribable symptoms. the aim of this review was to provide physicians with information to be aware and turn their attention to the patient’s symptoms, which are the most important clue to diagnosis of rls.
