Restless legs syndrome in end-stage renal disease: Clinical characteristics and associated comorbidities.

BACKGROUND: Despite being frequently described in patients with end-stage renal disease (ESRD), clinical characteristics and comorbidities in association with restless legs syndrome (RLS) are still to be confirmed. OBJECTIVES: The aim of this study was to investigate clinical factors associated with RLS in ESRD patients in hemodialysis. METHODS: This is a cross-sectional study of 400 patients on hemodialysis, evaluating RLS, clinical features and other sleep abnormalities. RESULTS: Out of 400, 86 patients presented RLS (21.5%; mean age 48.8+/-13.8y), being more frequent in females (p<0.005)…

Restless Legs Syndrome (RLS) and Parkinson's disease (PD)-related disorders or different entities?

The relationship between Restless Legs Syndrome (RLS) and Parkinson's disease (PD) is still controversial. Most genetic, pathological, and imaging data argue against a close association of these two disorders. Still, many studies reported an increased prevalence of RLS in PD patients. These studies are difficult to interpret because the current diagnostic criteria for RLS have not been validated in PD patients. Although many PD patients suffer from motor restlessness due to parkinsonism and may thus mimic RLS, the risk for (secondary) RLS in PD patients is probably slightly increased. This rev…

Valvular heart disease associated with taking low-dose pergolide for restless legs syndrome.

A 49-year-old female took low-dose pergolide (625 microg daily) for approx. 5 years (approximately cumulative dose 1.140 g/5 years) for the treatment of restless legs syndrome. She developed moderate to severe mitral and aortic valve insufficiency, requiring semi-urgent double-valve replacement. The initial diagnosis of rheumatic valve disease was refuted on histological examination of the valves due to the lack of typical calcification and neovascularization. Valvular heart disease is associated with the use of dopamine agonists for the treatment of Parkinson's disease and obesity, typically …

Genetic association studies of neurotensin gene and restless legs syndrome in French Canadians.

BACKGROUND AND PURPOSE: The neurotensin gene (NTS), a known dopamine modulator, is located within the candidate region for the first genetic locus of restless legs syndrome (RLS1) on chromosome 12q. Though no causative mutation was found in selected patients in a previous mutation analysis, the involvement of NTS in RLS cannot be completely excluded as a potential positional and functional candidate gene. The purpose of the current study is to further explore the NTS gene for potential functional variant(s) in its entire genomic and potential regulatory regions and their possible association w…

Restless legs syndrome and motor activity during sleep in spinocerebellar ataxia type 6.

BACKGROUND AND PURPOSE: We investigated the frequency of restless legs syndrome (RLS) and sleep disturbance in spinocerebellar ataxia type 6 (SCA6). PATIENTS AND METHODS: Five patients out of three multigenerational SCA6 families underwent a standardized investigation protocol including clinical interview for RLS, neurophysiological evaluation as well as the clinical assessment of ataxia. Polysomnography (PSG) was performed during two consecutive nights. RESULTS: Two out of five patients fulfilled the clinical criteria for RLS. A periodic leg movements in sleep (PLMS) index>15/h was present …

Restless legs syndrome and attention-deficit/hyperactivity disorder: a review of the literature.

STUDY OBJECTIVE: To review evidence on the association between restless legs syndrome (RLS) and attention-deficit/hyperactivity disorder (ADHD), to discuss the hypothetical mechanisms underlying this association, and to consider the potential interest for common pharmacologic treatments of RLS and ADHD when co-occurring. METHOD: A PubMed search. RESULTS: In clinical samples, up to 44% of subjects with ADHD have been found to have RLS or RLS symptoms, and up to 26% of subjects with RLS have been found to have ADHD or ADHD symptoms. Several mechanisms may explain this association. Sleep disrup…

Restless legs syndrome and periodic limb movements of sleep: fact, fad, and fiction.

Restless legs syndrome (RLS) and periodic limb movements of sleep (PLMS) are common disorders seen in sleep disorder centers. Although RLS in universally thought to cause daytime sleepiness, the role of PLMS in causing sleepiness (or any symptom!) has been more controversial. Recent publications have show that PLMS do not cause either subjective or objective sleepiness, but may be a marker for respiratory effort related arousals. In regards to patients with end-stage renal disease, PLMS may mark mortality. In this same group of patients, gabapentin and normalization of hematocrit may be effect…

Clinical symptomatology and treatment of restless legs syndrome and periodic limb movement disorder.

Patients with restless legs syndrome (RLS) suffer from sensory and motor symptoms evoked in the limbs at rest. Symptoms increase in the evening and during the night. The circadian rhythm and the presence of involuntary periodic limb movement in sleep (PLMS) which are frequently associated with arousals probably cause the leading symptom of sleep disturbances in RLS. Patients who do not have typical RLS symptoms but whose polysomnography shows PLMS that either impact on sleep continuity or daytime functioning are diagnosed as having the periodic limb movement disorder (PLMD). Dopaminergic agent…

Restless legs syndrome and nocturnal myoclonus: initial clinical manifestation of familial amyloid polyneuropathy.

Restless legs syndrome was the first isolated clinical manifestation in four siblings of a family with familial amyloid polyneuropathy. Clinical and electrophysiological evidence of peripheral neuropathy appeared after a variable time interval. Polysomnography showed abnormal sleep patterns and nocturnal myoclonus in all patients. The restless legs syndrome responded favourably to clonazepam.

Secondary overactive bladder syndrome with restless legs syndrome following cerebral infarction: report of 2 cases.

BACKGROUND: Previous research has commonly regarded overactive bladder syndrome (OAB) and restless legs syndrome (RLS) as distinct disorders in terms of their underlying causes, clinical diagnosis, and treatment approaches. However, there is evidence of an overlap in the occurrence of these two conditions following cerebral infarction(CI). Specifically, restless bladder syndrome (RBS), a subtype of RLS, exhibits symptoms similar to those of OAB. Consequently, further investigation is warranted to better understand the relationship between these two disorders. CASE PRESENTATION: In this report…

Pontine warning syndrome and restless legs syndrome secondary to paramedian pontine infarction: a case report.

Pontine warning syndrome (PWS) occurs rarely and is characterized by recurrent, stereotyped episodes of motor or sensory dysfunction, dysarthria, or ophthalmoplegia leading to pontine infarction. Restless legs syndrome (RLS) is a distinct neurological sensorimotor disorder. Pontine infarction is a rare but possible cause of RLS. Here, we report the case of a 58-year-old woman who experienced unilateral RLS in concomitance with stereotyped episodes of left-sided weakness and dysarthria, and developed an acute paramedian pontine infarction eventually. To the best of our knowledge, no other cases…

Palmitoylethanolamide (PEA) in the treatment of restless legs syndrome: Rationale and case report.

Restless legs syndrome (RLS) is a common, sleep-related, neurological disorder. Various treatments are available but some have side effects. Therefore, alternative treatment options with minimal side effects are being actively sought. Palmitoylethanolamide (PEA) is an endogenous lipid signalling molecule known to have anti-inflammatory and analgesic properties. According to the literature, oral PEA supplementation can decrease the levels of pain associated with central and peripheral neurological conditions, such as migraine and peripheral neuropathy. For the first time, we report of a gabapen…

Peripheral Neuropathy and Restless Legs Syndrome in Cirrhosis: An Electrophysiological Cross-sectional Study.

BACKGROUND/AIMS: Peripheral neuropathy (PN) and restless leg syndrome (RLS) are common in patients with cirrhosis. We report the PN profile in cirrhosis, with or without RLS. METHODS: This cross-sectional study included nondiabetic adults (aged ≥18 years) with cirrhosis who were screened for RLS. Participants with recent (<4 weeks) deterioration of liver disease, hemodynamic instability, overt neuropathy, neurological illness, pregnancy, chronic kidney disease, using psychotropic drugs, or uncontrolled systemic illness were excluded. RLS was diagnosed according to standard criteria. Nerve con

Синдром неспокойных ног: сетевая модель нейромодуляции железа-депендента-Нарративный обзор.

Синдром нервных ног (RLS) традиционно концептуализируется как сенсорное расстройство, реагирующее на допамин; однако новые данные говорят о более сложной и неоднородной нейробиологической основе. Результаты нейроимации, генетических исследований, циркадийской биологии и клинических исследований свидетельствуют о том, что допаминергическая дисфункция происходит в более широком контексте нейромодуляционного дисбаланса, включая метаболизм железа, аденозингергическую сигнализацию, глютаматергию и, возможно, норадренергические пути. Наряду с этим количественное картирование уязвимости и связанные с

Restless legs syndrome (RLS) is traditionally conceptualized as a dopamine-responsive sensorimotor disorder; however, new evidence suggests a more complex and heterogeneous neurobiological basis. Findings from neuroimaging, genetic studies, circadian biology, and clinical research indicate that dopaminergic dysfunction occurs within a broader context of neur…

The association between vitamin D and restless legs syndrome following acute ischemic stroke.

Restless legs syndrome (RLS) and acute ischemic stroke are prevalent conditions in neurology. Several studies have indicated a relationship between RLS, acute ischemic stroke, and vitamin D levels. This study aimed to evaluate vitamin D levels in patients with RLS after acute ischemic stroke, compared to those with only acute ischemic stroke, to determine if there is a significant association. A case-control study included 270 patients with acute ischemic stroke and 53 patients who developed RLS following acute ischemic stroke. The International Restless Legs Syndrome Study Group (IRLSSG) scal…

The complexities in the differential diagnosis of restless legs syndrome (Willis-Ekbom disease).

INTRODUCTION: We present a literature review on the clinical conundrums surrounding the differential diagnosis of restless legs syndrome (RLS, Willis-Ekbom disease), as well as conditions that can mimic RLS. An extensive literature search showed that secondary causes of RLS ranged from commonly recognized causes, such as iron deficiency anemia, to less widely noted causes, such as rheumatoid disorders and hypothyroidism. There is a controversial association with Parkinson's disease, essential tremor, and RLS, whereby RLS is proposed as a prodromal feature. AREAS COVERED: The clinical presenta…

Restless legs syndrome, neuroleptic-induced akathisia, and opioid-withdrawal restlessness: shared neuronal mechanisms?

Restlessness is a core symptom underlying restless legs syndrome (RLS), neuroleptic-induced akathisia, and opioid withdrawal. These three conditions also share other clinical components suggesting some overlap in their pathophysiology. Recent prospective studies demonstrate the frequent incidence of RLS-like symptoms during opioid withdrawal and supervised prescription opioid tapering. Based on the therapeutic role of µ-opioid receptor (MOR) agonists in the three clinical conditions and recent preclinical experimental data in rodents, we provide a coherent and unifying neurobiological basis fo…
