Background And Purpose: To explore aspects of restless legs syndrome (RLS) associated with detrimental impact on health-related quality of life (HRQoL).
Patients And Methods: The RLS epidemiology, symptoms, and treatment (REST) survey included SF-36 data on adults with RLS symptoms in the USA and five European countries. Linear regression models on each SF-36 dimension score explored factors influencing HRQoL in this population.
Results: Of 16,202 people surveyed, 7% screened positively for RLS. Severity of RLS symptoms was strongly associated with impaired physical and mental HRQoL in both the cohorts from the USA and Europe. Distress and symptom frequency also had predictive capability. In addition, significantly diminished HRQoL was associated with the use of prescription medication for RLS symptoms. Age, number of comorbidities, and number of physician visits were statistically associated with lower HRQoL in respondents with RLS.
Conclusions: Diminished HRQoL was partly accounted for by a number of RLS-related factors, including frequency, severity, and distress from symptoms. The negative impact of prescription medications on HRQoL, in contrast to demonstrated improvements with dopamine agonists, suggests inappropriate or ineffective medications are being used in this population. Our results strongly support the need for better physician education, both to diagnose the condition and importantly provide appropriate treatment with dopamine agonists, the only class of medication, that has been shown to improve the HRQoL of patients with RLS.

Restless legs syndrome (RLS) is characterized by an uncomfortable urge to move the legs, worsened in the evening, occurring at rest, and relieved temporarily by movement. Although its pathophysiology remains incompletely understood, oxidative stress has been suggested. Uric acid (UA) is a marker associated with oxidative stress, and its reduced levels pose a risk for certain neurodegenerative diseases.

Although many studies have indicated a significant association between migraine and restless legs syndrome (RLS), few long-term longitudinal studies have examined RLS in patients with migraine. We conducted a single-center, 12-year, longitudinal study of migraine patients and assessed whether RLS was present in 2010, 2017, or 2022 to evaluate its associations with clinical factors. Headache-related disability was assessed using the Migraine Disability Assessment (MIDAS).

Background: About 30% of ischemic strokes do not have a clear cause, which is called cryptogenic stroke (CS). Increasing evidence suggests a potential link between CS and right-to-left shunt (RLS). RLS may lead to CS via paradoxical embolic mechanism.

Article Synopsis
- The study examines white matter lesions (WMLs) in migraine patients with right-to-left shunts (RLS), focusing on their location, severity, and impact on brain volume and headaches.
- Researchers analyzed data from 102 migraine sufferers with RLS, including RLS flow and headache impact scores, comparing them with healthy controls.
- Findings indicate WMLs mainly occur in specific brain regions, show no significant correlation with RLS flow, but highlight differences based on headache severity and brain structure between migraines and healthy individuals.

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.
