BACKGROUND: Most children in Western populations do not meet recommendations for fish consumption. Oily fish is an important source of n-3 long-chain polyunsaturated fatty acids (LCPUFA), which reduce blood pressure and plasma triacylglycerol in adults and may affect cognitive development and behavior. However, to our knowledge, the potential effects of oily fish on cardiometabolic health, cognitive function, and behavior in children have not been investigated. The aim of the FiSK Junior study is to investigate the effects of oily fish consumption on cardiovascular risk markers, cognitive function, and behavior in healthy children...

BACKGROUND: A disturbed circadian rhythm seems to be a causal factor in the occurrence of depressive disorders in patients with Parkinson's disease (PD). The circadian rhythm can be restored with light. Therefore, Bright Light Therapy (BLT) might be a new treatment option for depression in PD patients. METHODS/DESIGN: In this double-blind controlled trial, 84 subjects with idiopathic PD are randomized to either BLT or a control light condition. The BLT condition emits white light with an intensity of 10,000 Lux, while the control device emits dim white light of 200 Lux, which is presumed to be too low to influence the circadian rhythm...

PURPOSE: Between 14 and 85 % of patients report noticeable changes in cognitive function during chemotherapy (CTX). The purposes of this study were to determine which demographic, clinical, and symptom characteristics were associated with inter-individual variability in initial levels of attentional function as well as with changes in the trajectories of attentional function in a sample of oncology patients who received two cycles of CTX. METHODS: Oncology outpatients (n = 1329) were recruited from two comprehensive cancer centers, one veteran's affairs hospital, and four community-based oncology programs...

In recent years sleep-related memory consolidation has become a central topic in the sleep research field. Several studies have shown that in healthy individuals sleep promotes memory consolidation. Notwithstanding this, the consequences of sleep disorders on offline memory consolidation remain poorly investigated. Research studies indicate that patients with insomnia, obstructive sleep apnea, and narcolepsy often exhibit sleep-related impairment in the consolidation of declarative and procedural information...

Parkinson's disease (PD) is a heterogeneous neurological disorder with a variety of motor and non-motor symptoms. The underlying mechanisms of these symptoms are not fully understood. An increased interest in structural connectivity analyses using diffusion tensor imaging (DTI) in PD has led to an expansion of our understanding of the impact of abnormalities in diffusivity on phenotype. This review outlines the contribution of these abnormalities to symptoms of PD including bradykinesia, tremor and non-tremor phenotypes, freezing of gait, cognitive impairment, mood, sleep disturbances, visual hallucinations and olfactory dysfunction...

PURPOSE OF REVIEW: It was first proposed in the late 1990s that objective markers of sleep disturbance could serve as an index of the biological severity of insomnia. In 2013, a heuristic model of two insomnia phenotypes based on objective sleep duration was proposed. Herein, we review the studies conducted in the past 3 years on the insomnia with short sleep duration phenotype and its implications for a clinical research agenda. RECENT FINDINGS: Studies have shown that insomnia with objective short sleep duration is associated with physiologic hyperarousal and cardiometabolic and neurocognitive morbidity, whereas insomnia with normal sleep duration is not...

BACKGROUND AND AIMS: Melatonin (MT), a naturally occurring pituitary hormone has a sleep promoting effect. There are very few studies on pre-operative oral MT (0.2-0.5 mg/kg) in children. We planned a study to assess the efficacy of oral MT in two doses and compare it with oral midazolam and placebo for pre-operative anxiolysis, sedation, maintenance of cognition and psychomotor skills, parental separation behaviour and venepuncture compliance. METHODS: This prospective double-blind randomised study was conducted after ethical committee approval on 100 children aged 5-15 years, American Society of Anaesthesiologists physical status I and II undergoing elective surgery at our hospital from January 1, 2014, to December 31, 2014...

Although Blacks sleep between 37 and 75min less per night than non-Hispanic Whites, research into what drives racial differences in sleep duration is limited. We examined the association of anxiety sensitivity, a cognitive vulnerability, and race (Blacks vs. White) with short sleep duration (<7h of sleep/night), and whether anxiety sensitivity mediated race differences in sleep duration in a nationally representative sample of adults with cardiovascular disease. Overall, 1289 adults (115 Black, 1174 White) with a self-reported physician/health professional diagnosis of ≥1 myocardial infarction completed an online survey...

Objective: To evaluate the efficacy of Bailemian capsule combined with self-help cognitive behavioral therapy (CBTI-SH) in treatment of chronic insomnia. Methods: Approved by the Ethics Committee of the hospital, 60 patients with chronic insomnia were randomly divided into two groups, the test group (Bailemian capsule combined with CBTI-SH) and the control group (CBTI-SH alone). Each group contained 30 cases. After 4 weeks for therapy, the sleep quality, mood and adverse reactions of treatment in patients were evaluated by sleep diary, sleep severity index scale (ISI), self-rating anxiety scale (SAS), self-rating depression scale (SDS) and treatment emergent symptom scale (TESS) respectively...

During hippocampal sharp wave/ripple (SWR) events, previously occurring, sensory input-driven neuronal firing patterns are replayed. Such replay is thought to be important for plasticity-related processes and consolidation of memory traces. It has previously been shown that the electrical stimulation-induced disruption of SWR events interferes with learning in rodents in different experimental paradigms. On the other hand, the cognitive map theory posits that the plastic changes of the firing of hippocampal place cells constitute the electrophysiological counterpart of the spatial learning, observable at the behavioral level...

In two studies, the relationship between sleep and working memory performance was investigated in children born very preterm (i.e., gestation less than 32 weeks) and the possible mechanisms underlying this relationship. In Study 1, parent-reported measures of snoring, night-time sleep quality, and daytime sleepiness were collected on 89 children born very preterm aged 6 to 7 years. The children completed a verbal working memory task, as well as measures of processing speed and verbal storage capacity. Night-time sleep quality was found to be associated with verbal working memory performance over and above the variance associated with individual differences in processing speed and storage capacity, suggesting that poor sleep may have an impact on the executive component of working memory...

Sexual abuse is very common. In the Netherlands 42% of women and 13% of men aged over 25 years have experienced unacceptable sexual behaviour. Most victims do not seek professional help nor do they report the abuse to the police, and most of the victims who do seek medical help do not mention the abuse. Doctors often do not recognize the signs of sexual abuse. Most victims of rape have symptoms that may develop into posttraumatic stress disorder (PTSD) if they persist for more than 4 weeks, such as sleep problems or panic attacks...

PURPOSE: Inflammatory bowel disease has been associated with neurological symptoms including restless legs syndrome. Here, we investigated the impact of restless legs syndrome in patients with inflammatory bowel disease on sleep, fatigue, mood, cognition, and quality of life. METHODS: Two groups of inflammatory bowel disease patients, with and without restless legs syndrome, were prospectively evaluated for sleep disorders, fatigue, daytime sleepiness, depression, anxiety, and health-related quality of life...

OBJECTIVE: Cognitive impairment is one of the major consequences of epilepsy and has been shown to reduce quality of life. Interictal epileptiform discharges (IEDs) were associated with poorer cognitive performance in children, and the aim of this study was to determine whether there was a similar association in adults. METHODS: A prospective cohort of 167 seizure-free adult patients underwent EEG recording and extensive cognitive evaluations. Global cognition was evaluated using Addenbrooke's Cognitive Examination-Revised (ACE-R), while sub-dimensions of cognition were evaluated using the Auditory Verbal Learning Test (AVLT), Trial Making Test (TMT)-A and -B, and the 5 constitutive subscales of ACE-R...

Aiming to identify new antipsychotic lead-compounds, our group has been working on the design and synthesis of new N-phenylpiperazine derivatives. Here, we characterized LASSBio-1422 as a pharmacological prototype of this chemical series. Adult male Wistar rats and CF1 mice were used for in-vitro and in-vivo assays, respectively. LASSBio-1422 [1 and 5 mg/kg, postoperatively (p.o.)] inhibited apomorphine-induced climbing as well as ketamine-induced hyperlocomotion (1 and 5 mg/kg, p.o.), animal models predictive of efficacy on positive symptoms...

BACKGROUND: Sleep is integral to biologic function, and sleep disruption can result in both physiological and psychologic dysfunction including cognitive decline. Surgery activates the innate immune system, inducing neuroinflammatory changes that interfere with cognition. Because surgical patients with sleep disorders have an increased likelihood of exhibiting postoperative delirium, an acute form of cognitive decline, we investigated the contribution of perioperative sleep fragmentation (SF) to the neuroinflammatory and cognitive responses of surgery...

OBJECTIVE: To test the hypothesis that adverse effects of statins are only reported in excess in observational studies and not in blinded randomized trials. DESIGN AND METHOD: We collated all reported AEs in hypertensive patients in the Lipid-Lowering arm of the Anglo-Scandinavian Cardiac Outcomes Trial (ASCOT-LLA) during the randomised, double-blind phase (when atorvastatin was compared with placebo) and the subsequent non-randomised un-blinded LLA-extension phase (when patients were offered open-label statin)...

INTRODUCTION: Disrupted sleep is common among children with autism spectrum disorder (ASD). AIMS: Our goal was to (1) examine the contribution of sleep problems to parenting stress in children with ASD as compared to typically developing (TD) and (2) to address maternal sleep-related cognitions and behaviors in both groups. METHODS: Mothers of 34 ASD (mean age = 39.29 months, SD = 5.22) and 31 TD children (mean age = 36.23 months, SD = 5.75) completed questionnaires measuring maternal stress, sleep-related cognitions and settling to sleep interactions, and the child's sleep problems; mothers in the ASD group completed a symptom severity questionnaire...

Sleep specialists have proposed measures to counteract the negative short- and long-term consequences of sleep debt, and some have suggested the nap as a potential and powerful "public health tool". Here, we address this countermeasure aspect of napping viewed as an action against sleep deprivation rather than an action associated with poor health. We review the physiological functions that have been associated positively with napping in both public health and clinical settings (sleep-related accidents, work and school, and cardiovascular risk) and in laboratory-based studies with potential public health issues (cognitive performance, stress, immune function and pain sensitivity)...
