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)
Rapid eye movement (REM) sleep behavior disorder (RBD) is frequently associated with Parkinson's disease (PD) and may anticipate its diagnosis by several years. We assessed the presence of motor dyscontrol during REM sleep in treatment-naïve PD patients and investigated the putative effect of levodopa (L-dopa) treatment on motor activity. Overnight sleep(More)
STUDY OBJECTIVE To investigate circadian changes in dopaminergic function by means of a neuroendocrine challenge (growth hormone and prolactin responses to an acute oral administration of L-dopa) in patients with idiopathic restless legs syndrome (RLS) and controls. DESIGN Randomized administration of the L-dopa neuroendocrine challenge. SETTING Sleep(More)
STUDY OBJECTIVES To investigate potential stimulant and anticataplectic effects of 10 mg reboxetine in patients diagnosed with narcolepsy. DESIGN 12 patients were treated for a 2-week period with 10 mg reboxetine under open conditions. The dosage of reboxetine was gradually increased between Day 1 and Day 9. Outcome parameters consisted of nightime(More)
OBJECTIVES The aim of this study was to test the external validity of the International Restless Legs Scale (IRLS) by assessment of the correlation between IRLS scores and objective measures of severity such as polysomnography (PSG) and Suggested Immobilization Test (SIT). DESIGNS Correlation analysis between rating scales for RLS (IRLS and Johns Hopkins(More)
BACKGROUND It is often assumed that most patients with restless legs syndrome (RLS) only experience symptoms at night. However, previous studies have estimated the prevalence of daytime symptoms to be 10-60%. This study sought to investigate the prevalence and pattern of daytime symptoms in patients with moderate-to-severe RLS. METHODS Observational,(More)
Several pieces of evidence suggest that a dopaminergic dysfunction might play a key role in the pathophysiology of restless legs syndrome (RLS), including the therapeutic effects of dopaminergic drugs and the results of several positron emission tomography and single photon emission computed tomography studies. However, RLS symptoms display a distinct(More)
A 74-year-old patient with idiopathic Parkinson's disease was evaluated for unintended sleep episodes that occurred after long-term treatment with 400 mg/day of L-dopa. Overnight sleep studies and multiple sleep latency testing were carried out under double-blind administration of either L-dopa or placebo. Mean sleep latency with L-dopa was 7 minutes, in(More)
