Schizophrenia is a major psychiatric disorder that has a massive, long-lasting negative impact on the patients as well as society. While positive symptoms (i.e., delusions and hallucinations), negative symptoms (i.e., anhedonia, social withdrawal), and cognitive impairments are traditionally considered the most prominent features of this disorder, the role of sleep and sleep disturbances has gained increasing prominence in clinical practice. Indeed, the vast majority of patients with schizophrenia report sleep abnormalities, which tend to precede illness onset and can predict an acute exacerbation of psychotic symptoms...

A major role of genetic factors in the risk of developing restless legs syndrome (RLS) is supported by the high frequency of positive family history of RLS in patients affected with this disease, and the higher concordance rates in monozygotic twins compared with dizygotic ones in twin studies. In this review we have focused on those reports describing inheritance patterns of RLS, genetic anticipation, the results of studies performed on positivity of family history of RLS, twin studies, linkage studies in familial RLS, genome-wide association studies (GWAS), exome sequencing studies, and case-control association studies on candidate genes in RLS...

OBJECTIVE: Restless legs syndrome (RLS) is a common neurological disorder characterized by an urge to move the legs along with paraesthesia deep within them. In this study, we aimed to use diffusion tensor imaging (DTI) and regional homogeneity (ReHo) to investigate the changes in regional spontaneous brain activity change for RLS patients against age- and gender-matched normal control (NC) subjects. METHODS: A total of 35 RLS patients and 27 age- and gender-matched NC subjects were recruited for group comparison research that used DTI and ReHo techniques...

OBJECTIVES: Restless legs syndrome (RLS) is a neurological disorder that is frequently misdiagnosed, resulting in delays in proper treatment. The objective of this study was to analyze the cost-utility of training primary care providers (PCP) in early and accurate diagnosis of RLS. METHODS: We used a Markov model to compare two strategies: one where PCPs received training to diagnose RLS (informed care) and one where PCPs did not receive training (standard care)...

OBJECTIVE: The association between restless legs syndrome (RLS) and obstructive sleep apnea syndrome (OSAS) has seldom been reported. There is one study reporting improvement of RLS symptoms severity in patients naive of treatment after initiation of continuous positive airway pressure (CPAP) for OSAS. The aim of this study was to evaluate the impact of the OSAS treatment in patients with previously diagnosed, clinically significant RLS in a usual clinical setting. METHODS: This was a retrospective study of RLS patients from a sleep clinic with a concomitant or subsequent diagnosis of OSAS...

BACKGROUND: Restless legs syndrome is a prevalent chronic neurological disorder with potentially severe mental and physical health consequences. Clearer understanding of the underlying pathophysiology is needed to improve treatment options. We did a meta-analysis of genome-wide association studies (GWASs) to identify potential molecular targets. METHODS: In the discovery stage, we combined three GWAS datasets (EU-RLS GENE, INTERVAL, and 23andMe) with diagnosis data collected from 2003 to 2017, in face-to-face interviews or via questionnaires, and involving 15 126 cases and 95 725 controls of European ancestry...

Brain-derived neurotrophic factor (BDNF) critically controls the fate and function of the neuronal network and has received much attention as a target of many brain diseases. Dopaminergic system dysfunction has also been implicated in a variety of neuropsychiatric diseases. Rotigotine, a non-ergot dopamine receptor agonist, is used in the treatment of Parkinson's disease and restless legs syndrome. To investigate the effects of rotigotine on neuronal functions both in vivo and in vitro, rats and primary cortical neurons were administered rotigotine, and the mRNA and protein expression levels of BDNF, its receptor TrkB and downstream signaling molecules, and synaptic proteins were determined...

Incidence and severity of both deep vein thrombosis and chronic venous insufficiency are increased with age. Today, however, the significance of these diseases in the elderly patient population are still poorly comprehended. Although most patients have a history of previous treatment, chronic venous insufficiency is usually encountered in the advanced clinical stage. As a result, there is an increase in mobility restrictions, the need for assistance in daily activities and the risk of falls in elderly patients...

INTRODUCTION: The relationship between the autonomic nervous system and restless legs syndrome (RLS) and periodic limb movements of sleep (PLMS) consists of varied and somewhat conflicting reports. In order to further elucidate these complexities, a retrospective analysis of polysomnography (PSG) records and clinical data was performed. METHODS: Records from 233 adult subjects were randomly selected and organized into one of four groups ("non-RLS/PLMS" [n=61], "RLS" [n=60], "PLMS" [n=58], and "RLS/PLMS" [n=54])...

Previous studies have shown that insomnia is a common sleep disorder in patients with end-stage renal disease. This study aims to determine the prevalence and risk factors of insomnia in our chronic hemodialysis (HD) patients. This is a cross-sectional study conducted in three HD units in Morocco. To assess the prevalence of insomnia, we used a specific questionnaire. Patients complaining of difficulty in falling asleep and/or nocturnal awakenings occurring seven nights a week during the last month were included in the group "insomnia;" the other patients were used as controls...
