Association Between Sleep-Related Leg Movements and Diabetes Prevalence: A Cohort Study From the United States.

Background Sleep is integral to cardiometabolic health. While there is emerging evidence linking sleep-related leg movements (SRLM) to diabetes mellitus (DM), the underlying mechanisms remain unclear. This study investigates the association between SRLM and DM prevalence in a national population-based cohort study in the United States (US), considering potential mediators like short sleep duration and inflammation and examining variations across age, sex, and race/ethnicity.

Characterizing Parkinson's Disease Clinical and Biomarker Interactions in REM Sleep Behavior Disorder.

Background: REM Sleep Behavior Disorder (RBD), marked by dream enactment due to loss of REM-related muscle atonia, is a prominent prodromal indicator of synucleinopathies, particularly Parkinson's Disease (PD).

Objectives: This study aimed to investigate the interplay among key PD biomarkers- α-synuclein seed amplification assay (SAA), hyposmia, and dopamine transporter (DaT) SPECT imaging - in individuals with RBD. Additionally, we evaluated how phenoconversion events and Movement Disorder Society (MDS)-Prodromal PD probability scores relate to clinical symptoms and biomarker profiles in an incident RBD population.

Sex differences in cerebrospinal fluid proteomics of patients with restless legs syndrome.

Study Objectives: The pathobiology of restless legs syndrome (RLS) remains poorly understood, complicating effective treatment. This observational cross-sectional study aimed to identify a cerebrospinal fluid proteomic signature of RLS and to explore sex-specific differences in cerebrospinal fluid proteomics.

Methods: Cerebrospinal fluid samples were collected from 22 untreated RLS patients and 18 controls, matched for age, body mass index, and sex.

Impact of continuous positive airway pressure therapy on restless legs syndrome in patients with coexistent obstructive sleep apnea: A qualitative systematic review.

Introduction: Obstructive sleep apnea (OSA) is characterized by repetitive episodes of complete or partial upper airway collapse during sleep. Restless legs syndrome (RLS) is a sleep-related movement disorder characterized by an uncomfortable urge to move the legs, especially during inactivity and evenings. Both OSA and RLS are common with significant overlap: RLS is present in up to 36% of those with OSA.

Patient Insights on Integrating Sleep Apnea Testing into Routine Stroke and TIA Care.

AHA/ASA guidelines recommend patients with ischemic stroke or transient ischemic attack (TIA) be considered for obstructive sleep apnea (OSA) evaluation, given the high prevalence of OSA and improved outcomes for cerebrovascular disease when OSA is treated. However, OSA testing has not been incorporated into routine cerebrovascular management. We interviewed 30 patients hospitalized for acute stroke/TIA at six Veterans Affairs facilities participating in a stepped-wedge implementation trial to improve timely OSA testing after stroke/TIA.

Treatment of restless legs syndrome and periodic limb movement disorder: an American Academy of Sleep Medicine clinical practice guideline.

Introduction: This guideline establishes clinical practice recommendations for treatment of restless legs syndrome (RLS) and periodic limb movement disorder (PLMD) in adults and pediatric patients.

Methods: The American Academy of Sleep Medicine (AASM) commissioned a task force of experts in sleep medicine to develop recommendations and assign strengths based on a systematic review of the literature and an assessment of the evidence using the grading of recommendations assessment, development, and evaluation methodology. The task force provided a summary of the relevant literature and the certainty of evidence, the balance of benefits and harms, patient values and preferences, and resource use considerations that support the recommendations.

Treatment of restless legs syndrome and periodic limb movement disorder: an American Academy of Sleep Medicine systematic review, meta-analysis, and GRADE assessment.

Introduction: This systematic review provides supporting evidence for the accompanying clinical practice guideline on the treatment of restless legs syndrome and periodic limb movement disorder.

Methods: The American Academy of Sleep Medicine commissioned a task force of experts in sleep medicine. A systematic review was conducted to identify studies that compared the use of pharmacological or nonpharmacological treatment to no treatment to improve patient-important outcomes.

The Melanocortin and Endorphin Neuropeptides in Patients with Restless Legs Syndrome.

Objective: Based upon similarities between the urge to move and sensory discomfort of restless legs syndrome (RLS) and properties of melanocortin hormones, including their incitement of movement and hyperalgesia, we assessed plasma and cerebrospinal fluid (CSF) α-melanocyte-stimulating hormone (α-MSH) and β-endorphin in RLS patients and controls.

Methods: Forty-two untreated moderate-to-severe RLS patients and 44 matched controls underwent venipuncture at 19:00, 20:30, and 22:00; 37 RLS and 36 controls had lumbar puncture at 21:30. CSF and plasma were analyzed for pro-opiomelanocortin (POMC), adrenocorticotropin hormone (ACTH), α-MSH, β-MSH, and β-endorphin by immunoassay.

Review of the role of the endogenous opioid and melanocortin systems in the restless legs syndrome.

Restless legs syndrome (RLS) is responsive to opioid, dopaminergic and iron-based treatments. Receptor blocker studies in RLS patients suggest that the therapeutic efficacy of opioids is specific to the opioid receptor and mediated indirectly through the dopaminergic system. An RLS autopsy study reveals decreases in endogenous opioids, β-endorphin and perhaps Met-enkephalin in the thalamus of RLS patients.

Differential impact of resilience on demoralization and depression in Parkinson disease.

Objectives: The objective of this study was to study the interrelations of demoralization, depression, and resilience in patients with Parkinson disease, and, more specifically, to determine if higher resilience in patients with Parkinson disease is associated with lower demoralization, lower depression, or both.

Methods: Outpatients with Parkinson disease ( = 95) were assessed for demoralization, depression, and resilience, as well as sociodemographic, clinical, and treatment-related variables. Bivariable associations, standard regressions, linear regression with copula correction, and correspondence analysis were used to analyze the data.

Impact of the coronavirus disease-2019 pandemic on Veterans Health Administration Sleep Services.

Objectives: To understand the impact of the coronavirus disease-2019 pandemic on sleep services within the United States Department of Veterans Affairs using separate surveys from "pre-COVID" and pandemic periods.

Methods: Data from a pre-pandemic survey (September to November 2019) were combined with data from a pandemic-period survey (August to November 2020) to Veterans Affairs sleep medicine providers about their local sleep services within 140 Veterans Affairs facilities).

Results: A total of 67 (47.

Urges to Move and Other Motivation States for Physical Activity in Clinical and Healthy Populations: A Scoping Review Protocol.

Motivation for bodily movement, physical activity and exercise varies from moment to moment. These motivation states may be "affectively-charged," ranging from instances of lower tension (e.g.

From Perceived Stress to Demoralization in Parkinson Disease: A Path Analysis.

Objectives: The objective of this study was to determine whether depression and anxiety are mediators between perceived stress and demoralization via a loss of the cognitive map to get out of the predicament manifesting as subjective incompetence.

Methods: Ninety-five consecutive outpatients with Parkinson's disease were evaluated for perceived stress, depression, anxiety, subjective incompetence, and demoralization using reliable and valid scales. Inclusion criteria were ages 40-90, intact cognition, and no current history of substance use.

Diagnostic and Treatment Considerations in Restless Legs Syndrome Complicated by Diabetic Neuropathy.

Purpose Of Review: Diabetic neuropathy from type I diabetes (DMI), type II diabetes (DMII), or gestational diabetes commonly occurs concurrently with restless legs syndrome (RLS) with an estimated prevalence in DMII specifically of 17.7 to 45%. The diagnosis of RLS can be obscured by symptoms of peripheral neuropathy, which may be similar to those of RLS, but also by other RLS mimics, including nocturnal leg cramps or akathisia.

The Management of Restless Legs Syndrome: An Updated Algorithm.

Restless legs syndrome (RLS) is a common disorder. The population prevalence is 1.5% to 2.

Impact of Obstructive Sleep Apnea on Cognitive and Motor Functions in Parkinson's Disease.

Introduction: Parkinson's disease (PD) is a chronic neurodegenerative disorder that presents with motor and non-motor manifestations. Amongst the non-motor features, various forms of sleep disturbances can occur, and obstructive sleep apnea (OSA) is considered to be a common comorbidity. We conducted this systematic review and meta-analysis to assess the impact of OSA on cognitive and motor functions in PD.
