Neurocognitive function in patients with idiopathic Restless Legs Syndrome before and after treatment with dopamine-agonist

Results showed that cognitive functions, impaired at baseline when compared to control subjects, improved after the pharmacological treatment, reaching the scores of healthy subjects. Decision making, problem solving and categorizing abilities, investigated by the Iowa Gambling Task (IGT) and the Wisconsin Card Sorting Test (WCST), resulted lower in RLS patients at baseline than in controls. All these functions improved after pharmacological treatment, as well as quality of life, depressive and anxiety symptoms, and daytime sleepiness.
