Functional connectivity and topology in patients with restless legs syndrome: a case-control resting-state functional magnetic resonance imaging study.

ABSTRACT:

Background and purpose

Functional connectivity studies revealed alterations within thalamic, salience, and default mode networks in restless legs syndrome patients.

Methods

Eighty-two patients with restless legs syndrome (untreated, n = 30; on dopaminergic medication, n = 42; on alpha-2-delta ligands as mono- or polytherapy combined with dopaminergic medication, n = 10), and 82 individually age- and gender-matched healthy controls were studied with resting-state functional magnetic resonance imaging. Connectivity of 12 resting-state networks was investigated with independent component analysis, and network topology was studied with graph methods among 410 brain regions.

Results

Patients with restless legs syndrome showed significantly higher connectivity within salien
