BACKGROUND Restless legs syndrome (RLS) is associated with common variants in three intronic and intergenic regions in MEIS1, BTBD9, and MAP2K5/LBXCOR1 on chromosomes 2p, 6p and 15q. METHODS Our study investigated these variants in 649 RLS patients and 1230 controls from the Czech Republic (290 cases and 450 controls), Austria (269 cases and 611 controls)(More)
OBJECTIVE To assess the efficacy of rotigotine transdermal patch in subjects with moderate to severe idiopathic restless legs syndrome (RLS) and periodic limb movement (PLM) in sleep in a double-blind, randomized, placebo-controlled, multicenter study (NCT00275236). METHODS Sixty-seven (46 rotigotine, 21 placebo) subjects applied rotigotine (maximum(More)
The orexin system is a key regulator of sleep and wakefulness. In a multicenter, double-blind, randomized, placebo-controlled, two-way crossover study, 161 primary insomnia patients received either the dual orexin receptor antagonist almorexant, at 400, 200, 100, or 50 mg in consecutive stages, or placebo on treatment nights at 1-week intervals. The primary(More)
In a case-control study with prevalence sampling, the authors explored the correlates for nocturia and their population-level impact. In 2003-2004, questionnaires were mailed to 6,000 subjects (aged 18-79 years) randomly identified from the Finnish Population Register (62.4% participated; 53.7% were female). Questionnaires contained items on medical(More)
Restless legs syndrome (RLS) is a sensorimotor disorder with an age-dependent prevalence of up to 10% in the general population above 65 years of age. Affected individuals suffer from uncomfortable sensations and an urge to move in the lower limbs that occurs mainly in resting situations during the evening or at night. Moving the legs or walking leads to an(More)
AIMS To clarify whether patients with obstructive sleep apnea syndrome (OSAS) have executive dysfunction, to identify the domains of executive function affected and to establish the severity of any dysfunction. METHODS A full-night polysomnography and a comprehensive neuropsychological assessment focusing on executive functions were conducted on 40 newly(More)
OBJECTIVE To evaluate the short- and long-term safety and efficacy of pergolide therapy for restless legs syndrome (RLS) in a double-blind, placebo-controlled, randomized trial (Pergolide European Australian RLS [PEARLS] study). METHODS We randomized 100 patients with idiopathic RLS were randomized to pergolide, 0.25 to 0.75 mg, in the evening or placebo(More)
The aims of this study are to clarify whether patients with obstructive sleep apnea syndrome (OSAS) have a decline in verbally or visually-based cognitive abilities and whether the possible decline is related to particular sleep depth changes. In addition, the effect of continuous positive airway pressure (CPAP) on the possible changes is investigated.(More)
This study addressed the question of whether there are any differences in the size and collapsibility of the upper airway measured by digital fluoroscopy, between snorers and controls whilst they were awake and breathing normally; and whether there are any correlations between these measurements and other clinical data. The dynamic changes of the upper(More)
AIMS To assess the impact of continuous positive airway pressure (CPAP) treatment on executive dysfunction in patients with obstructive sleep apnea syndrome (OSAS). METHODS At baseline, 20 OSAS patients and 17 healthy controls underwent polysomnography and neuropsychological assessment focusing on executive functions. After at least 6 months of CPAP(More)
