Restless legs syndrome in Parkinson's disease: relationship with quality of life and medication.

Objectives: We aimed to disclose the relationship between restless leg syndrome (RLS) and antiparkinsonian treatment, and its effect on quality of life (QoL) in patients with Parkinson's disease (PD).

Background: Previous studies documented the prevalence of RLS among patients with PD to be higher than in the general population, but conclusions regarding the aetiology and impact were contradictory.

Methods: We examined 101 patients with idiopathic PD.
