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)
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)
PATIENTS AND METHODS To assess the reliability, validity, and responsiveness of the International Restless Legs Syndrome Study Group's rating scale (the International Restless Legs Scale (IRLS)) (V2.0), using pooled data from two matching, placebo-controlled studies of ropinirole for treating Restless Legs Syndrome (RLS). RESULTS Pooled patient samples(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)
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)
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)
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)
CONTEXT Chronic fatigue syndrome (CFS) is associated with a dysregulated hypothalamic-pituitary adrenal axis and hypocortisolemia. OBJECTIVE To evaluate the efficacy and safety of low-dose oral hydrocortisone as a treatment for CFS. DESIGN A randomized, placebo-controlled, double-blind therapeutic trial, conducted between 1992 and 1996. SETTING A(More)
