Restless legs syndrome in Behçet's disease

Area of Science:

• Neurology
• Rheumatology
• Sleep Medicine

Background:

• Behçet's disease (BD) is a multisystem inflammatory disorder with known central nervous system involvement and neuropathies.
• The potential association between BD and Restless Legs Syndrome (RLS) has not been previously investigated.
• Understanding this link may offer insights into BD's neurological manifestations.

Purpose of the Study:

• To determine the prevalence of RLS in patients diagnosed with Behçet's disease.
• To explore the association between RLS and the clinical characteristics of BD.
• To investigate potential risk factors for RLS in the BD population.

Main Methods:

• A cross-sectional study comparing 109 BD patients with 104 healthy controls.
• Diagnosis of RLS was based on established criteria.
• Clinical features of BD were systematically recorded and analyzed for correlation with RLS.

Main Results:

• The prevalence of RLS was significantly higher in BD patients (29.4%) compared to controls (4.8%).
• No significant differences in BD clinical features were observed between BD patients with and without RLS.
• RLS severity showed a positive correlation with age in the BD cohort.

Conclusions:

• Restless Legs Syndrome is more prevalent in Behçet's disease patients and should be considered in their clinical management.
• The underlying mechanisms linking BD and RLS require further investigation.
• Routine screening for RLS in BD patients is recommended, particularly those with neurological involvement.
