Restless legs syndrome (RLS) is a common neurologic disorder whose prevalence has been estimated at 4 to 10% of the general population. Although its pathophysiology remains unknown, dopaminergic mechanisms are believed to play a central role. Furthermore, dopaminergic drugs have shown therapeutic efficacy in various large-scale therapeutic trials, and(More)
Hypothalamic-pituitary-adrenal system (HPA) function was tested in 24 patients with schizophrenia and compared to 24 age-matched healthy volunteers using the combined dexamethasone-suppression (DST/CRH) corticotropin-releasing hormone stimulation test (DST/CRH). After stimulation with CRH, the dexamethasone-pretreated patients released significantly more(More)
BACKGROUND Multiple lines of evidence suggest that brain serotonergic systems may be disturbed in seasonal affective disorder (SAD). Previously, we found that the serotonergic agent meta-chlorophenylpiperazine (m-CPP) produced increases in activation and euphoria in depressed patients with SAD, but not in patients with SAD following light treatment or in(More)
OBJECTIVE To assess the efficacy, safety, and tolerability of ropinirole in the treatment of patients with restless legs syndrome. METHODS A 12 week, prospective, double blind, randomised comparison involving 284 patients from 10 European countries. All participants had a score of > or =15 on the international restless legs scale (IRLS). Patients were(More)
Sleep disorders are common in Parkinson's disease (PD), as almost two thirds of PD patients report them. From a clinical point of view, they can be classified into disorders of initiation and maintenance of sleep (DIMS), parasomnias, and excessive daytime sleepiness (EDS). Among the causes of DIMS are degenerative changes in the CNS affecting centers for(More)
OBJECTIVE To assess the effects of gabapentin on sensory and motor symptoms in patients with restless legs syndrome (RLS). METHODS Patients with RLS (22 idiopathic, 2 secondary to iron deficiency) were randomized and treated for 6 weeks with either gabapentin or placebo. After a 1-week washout they crossed over to the alternative treatment for 6 weeks.(More)
BACKGROUND Continuous administration of a dopamine agonist could be used to treat patients with restless legs syndrome. Our aim was to investigate the efficacy of transdermal rotigotine in the treatment of idiopathic restless legs syndrome. METHODS In this randomised, double-blind, placebo-controlled trial, 458 patients with moderate-to-severe idiopathic(More)
In 2003, the EFNS Task Force was set up for putting forth guidelines for the management of the Restless Legs Syndrome (RLS) and the Periodic Limb Movement Disorder (PLMD). After determining the objectives for management and the search strategy for primary and secondary RLS and for PLMD, a review of the scientific literature up to 2004 was performed for the(More)
BACKGROUND Since the publication of the first European Federation of Neurological Societies (EFNS) guidelines in 2005 on the management of restless legs syndrome (RLS; also known as Willis-Ekbom disease), there have been major therapeutic advances in the field. Furthermore, the management of RLS is now a part of routine neurological practice in Europe. New(More)
