BACKGROUND: We examined whether current overall attention deficit hyperactivity disorder (ADHD), inattention, or hyperactivity symptom severities are associated with the current presence and persistent history of sleep problems. METHODS: N = 942 participants of the Netherlands Sleep Registry filled out online several validated questionnaires. Regression analyses were performed to assess the association between (1) current overall ADHD symptom severity and the current presence of sleep problems, (2) current ADHD symptom-severity groups and the persistent history of sleep problems, and (3) current inattention or hyperactivity symptom severities and the current presence of sleep problems...

Restless legs syndrome (RLS) is commonly treated with the dopamine agonists pramipexole, and rotigotine, which target the inhibitory dopamine receptor subtype D3R. While initially highly effective, these compounds lose their efficacy in treating RLS over time, and long-term therapy regularly leads to a worsening of the symptoms (augmentation). This dopamine agonist-induced augmentation has become a prime concern in the treatment of RLS, and while alternate therapies are being proposed, the mechanisms leading to augmentation remain opaque...

BACKGROUND/AIMS: In chronic kidney disease (CKD) patients blood pressure variability (BPV) is associated with poor outcome. Sleep disturbances alter BP profiles in hypertensives but their influence on BPV in CKD patients is unknown. We screened a cohort of CKD/ESRD patients to investigate whether sleep quality impacts on BPV. METHODS: Consecutive CKD patients' sleep quality was assessed using validated questionnaires (Epworth Sleepiness Scale-ESS); International Restless legs scale-IRLS; Functional Outcomes of Sleep Questionnaire-FOSQ: Insomnia Severity Index-ISI; STOP-Bang)...

Restless legs syndrome (RLS) is a sensorimotor neurological disturbance causing physical and psychological distress. Here, we investigated the severity and effect of depressive symptoms in RLS among a Korean cohort population. Depressive symptoms were more prevalent in the RLS group than in the non-RLS group [≥mild depression: odds ratio (OR)=1.95, p<0.001; ≥ moderate depression: OR=6.15, p<0.001; and ≥severe depression: OR=56.54, p<0.001], with a predominant proportion of severe depression (97%) in the RLS group...

Objective: Restless legs syndrome (RLS) is a highly heritable and common neurological sensorimotor disease disturbing sleep. The objective of study was to investigate significant gene for RLS by performing GWA and replication study in a Korean population. Methods: We performed a GWA study for RLS symptom group (n=325) and non-RLS group (n=2,603) from the Korea Genome Epidemiology Study. We subsequently performed a replication study in RLS and normal controls (227 RLS and 229 controls) to confirm the present GWA study findings as well as previous GWA study results...

Iron is essential for many biological functions including neurotransmitter synthesis, where the metal is a co-factor of tyrosine hydroxylase, which converts tyrosine to dopamine and further to norepinephrine. As the shared chemical structure, called catechol, may potentially bind iron we questioned whether tyrosine derived hormones would impact on cellular iron homeostasis in macrophages, which are central for the maintenance of body iron homeostasis. Using murine bone marrow-derived macrophages (BMDMs), we investigated the effect of catecholamines and found that only dopamine but neither tyrosine, nor norepinephrine, affected cellular iron homeostasis...

BACKGROUND: Spasticity and spasms are distressing features of the upper motor neuron syndrome (UMNS) following spinal cord injuries (SCI) or multiple sclerosis (MS), and have common therapeutic implications. Despite an increase of antispastic drugs and strategies, sometimes up to the surgical implant of intrathecal baclofen pump, some patients still complain of disabling spasms, which poses diagnostic and therapeutic challenges. Although clinically similar, flexor spasms due to pyramidal tract disruption must be clearly differentiated from periodic limb movements (PLM), often accompanying restless leg syndrome (RLS) and occurring during sleep...

OBJECTIVE: The restless legs syndrome (RLS) is characterized by sensory-motor symptoms which usually occur predominantly at rest in the evening and at night. It is assumed that this circadian rhythm is caused by low dopamine levels in the evening. Yet, it has never been investigated whether RLS patients show diurnal variations in cognitive functions modulated by dopamine and what neurophysiological and functional neuroanatomical processes underlie such modulations. METHODS: We used a Simon task combined with EEG and source localization to investigate whether top-down response selection and/or automatic visuo-motor priming are subject to diurnal changes in RLS patients, as compared to matched healthy controls...

OBJECTIVE: The first aim was to demonstrate a previously hypothesized increased sensitivity of corticostriatal glutamatergic terminals in the rodent with brain iron deficiency (BID), a pathogenetic model of restless legs syndrome (RLS). The second aim was to determine whether these putative hypersensitive terminals could constitute a significant target for drugs effective in RLS, including dopamine agonists (pramipexole and ropinirole) and α2 δ ligands (gabapentin). METHODS: A recently introduced in vivo optogenetic-microdialysis approach was used, which allows the measurement of the extracellular concentration of glutamate upon local light-induced stimulation of corticostriatal glutamatergic terminals...

Pregnant women are more likely to be affected by restless legs syndrome (RLS) than the general population. Restless legs syndrome during pregnancy is associated with adverse maternal and fetal outcomes. Currently unknown is the worldwide and regional prevalence of RLS in pregnant women. We performed a meta-analysis to provide a full profile of the prevalence of RLS during pregnancy. A systematic search of the PubMed, Medline, EMBASE, and Web of Science databases was performed to identify studies that were published up to April 2017, followed by random-effects meta-analyses...

An evening state of spinal hyperexcitability has been proposed to be a possible cause of evening increases in restless legs syndrome symptoms. Thus, the objective of the current study was to assess the circadian variation in spinal excitability in patients with restless legs syndrome based on flexor withdrawal reflex and crossed extensor reflex responses. The reflexes were elicited on 12 participants with restless legs syndrome and 12 healthy control participants in the evening (PM) and the morning (AM). Reflex response magnitudes were measured electromyographically and kinematically...
