Overview

Restless Legs Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an irresistible urge to move the legs, usually accompanied by uncomfortable sensations, primarily occurring during periods of rest

Restless Legs Syndrome (RLS) is a chronic neurological condition that causes an uncontrollable urge to move the legs, often accompanied by unpleasant sensations. These sensations are typically described as creeping, crawling, tingling, pulling, or aching. Symptoms usually worsen in the evening or at night and can be temporarily relieved by movement, such as walking or stretching. This can significantly disrupt sleep, leading to daytime fatigue, irritability, and impaired quality of life. The exact cause of RLS is not fully understood, but it is believed to involve a dysfunction in the brain's dopamine system, which controls muscle movement. Genetic factors may play a role, as RLS often runs in families. Iron deficiency, kidney failure, peripheral neuropathy, and pregnancy are also recognized as secondary causes or exacerbating factors. Management often involves lifestyle adjustments, addressing underlying conditions, and in some cases, medication to alleviate symptoms.

International evidence & guidelines

How global health authorities view Restless Leg Syndrome.

The Mayo Clinic acknowledges RLS as a common neurological disorder and suggests lifestyle changes, addressing underlying conditions like iron deficiency, and medications. The National Institute of Neurological Disorders and Stroke (NINDS) highlights the role of dopamine and iron in RLS. While conventional medicine often focuses on pharmaceuticals, these bodies also recognize the importance of non-pharmacological approaches, including exercise, avoiding triggers, and addressing nutritional deficiencies. NCCIH notes that some complementary approaches, like massage and yoga, may provide symptom relief for some individuals, but more research is needed for many herbal remedies.

  • Daridorexant and Insomnia in Clinical Practice: A Nominal Group Technique Consensus Study among Italian Sleep and Insomnia Experts.

    Ferini-Strambi L, Arnaldi D, Bonanni E, Cicolin A, Gigli GL, Liguori C · Current neuropharmacology · 2026

    Chronic insomnia disorder significantly affects cognitive, emotional, and physical health. Recently, the dual orexin receptor antagonist (DORA) daridorexant was approved for treating chronic insomnia in several countries. Given the limited evidence available, expert consensus was sought to clarify key clinical issues, inform practice, and guide future research. Thirteen Italian sleep experts employed the Nominal Group Technique (NGT) to identify and rank important clinical questions. The process involved independent thought generation, group discussion, and online voting using a 5-point Likert scale. The NGT process resulted in 55 statements across five key clinical questions, with relevance scores guiding their categorization into three tiers. Key findings highlight daridorexant's mechanism of action, safety profile, efficacy on night and day parameters, and suitability for long-term use. The experts emphasized cross-tapering strategies for switching from other hypnotics, the import

  • Italian Association of Sleep Medicine (AIMS) position statement and guideline on the treatment of menopausal sleep disorders.

    Silvestri R, Aricò I, Bonanni E, Bonsignore M, Caretto M, Caruso D · Maturitas · 2019

    Insomnia, vasomotor symptoms (VMS) and depression often co-occur after the menopause, with consequent health problems and reductions in quality of life. The aim of this position statement is to provide evidence-based advice on the management of postmenopausal sleep disorders derived from a systematic review of the literature. The latter yielded results on VMS, insomnia, circadian rhythm disorders, obstructive sleep apnea (OSA) and restless leg syndrome (RLS). Overall, the studies show that menopausal hormone therapy (MHT) improves VMS, insomnia, and mood. Several antidepressants can improve insomnia, either on their own or in association with MHT; these include selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), and mirtazapine. Long-term benefits for postmenopausal insomnia may also be achieved with non-drug strategies such as cognitive behavioral therapy (CBT) and aerobic exercise.

  • Fire Fighter Fatigue Management Program: Operation Fight Fatigue

    n=620 · NCT01672502 · COMPLETED · COMPLETED

    Firefighters frequently work extended duration shifts and long work weeks which have adverse effects on alertness, health, safety and performance. This protocol uses a survey instrument to examine the effects of extended duration shifts on safety outcomes (e.g., motor vehicle crashes, accidents, injuries), health (e.g., diagnosis and treatment of sleep disorders, improved general health indices, decreased number of sick days), and performance (e.g., decreased response time). This study will expand understanding of the nature, scope, etiology and consequences of firefighter fatigue and increase our ability to develop guidelines that can be generalized across fire departments throughout North America. This study could provide an avenue to make lasting policy improvements that could enhance the safety, health, and performance of firefighters.

  • Non-interventional Observational Study on the Influence of Pramipexole (PPX) on Sensory Symptoms of Restless Legs Syndrome (RLS)

    n=1504 · NCT00887289 · COMPLETED · COMPLETED

    The main goal of this open-label, prospective, non-controlled, non-interventional post marketing surveillance study is to evaluate how pramipexole treatment works when applied in actual practice. In actual practice patients who would have been excluded in the clinical registration studies of pramipexole in moderate to severe primary Restless Legs Syndrome (i.e. those with certain disease histories, co-morbidities and/or demographic characteristics) will also be treated with pramipexole. Thus, during this post marketing surveillance study additional information on the efficacy and safety of pramipexole in those patients will be obtained. The objectives of this post marketing surveillance study are: * To investigate the influence of Sifrol® (pramipexole) treatment on unpleasant sensory symptoms of Restless Legs Syndrome as measured with the short form of the McGill Pain Questionnaire. * To assess if improvement of sensory symptoms correlates with overall Restless Legs Syndrome severity (International Restless Legs Syndrome Scale for Severity) and with secondary symptoms like sleeping problems and daytime tiredness (items 1 \& 6 from Restless Legs Syndrome-6). * To evaluate if the treatment effect of Sifrol on overall Restless Legs Syndrome severity (International Restless Legs Syndrome Scale for Severity) differs between patients with high pain scores and patients with lower pain scores. * To compare General Practitioner and neurologist sites patient populations in terms of demographics, Restless Legs Syndrome severity at Visit 1 and treatment outcomes at Visit 3. * To evaluate the development of behavioural changes under pramipexole treatment.

Working alongside conventional care

Conventional treatment for RLS often involves dopamine agonists (e.g., pramipexole, ropinirole) or alpha-2 delta ligands (e.g., gabapentin, pregabalin). Opioids and benzodiazepines may be used in severe cases. These medications can have side effects, and some may lead to augmentation (worsening of RLS symptoms over time).
