BACKGROUND: Insomnia is a common health problem, and most people who seek help for insomnia consult primary care. In primary care, insomnia treatment typically consists of hypnotic drugs, although cognitive behavioral therapy for insomnia is the recommended treatment. However, such treatment is currently available to few primary care patients. OBJECTIVES: To evaluate the effects of a group treatment program for insomnia led by nurses in primary care. OUTCOMES: were the Insomnia Severity Index, a 2-week sleep diary, and a questionnaire on frequency of hypnotic drug use...

The right and left side of the brain are asymmetric in anatomy and function. We review electrophysiological (EEG and event-related potential), behavioral (dichotic and visual perceptual asymmetry), and neuroimaging (PET, MRI, NIRS) evidence of right-left asymmetry in depressive disorders. Recent electrophysiological and fMRI studies of emotional processing have provided new evidence of altered laterality in depressive disorders. EEG alpha asymmetry and neuroimaging findings at rest and during cognitive or emotional tasks are consistent with reduced left prefrontal activity in depressed patients, which may impair downregulation of amygdala response to negative emotional information...

Neuronal nicotinic acetylcholine receptors (nAChRs) participate in diverse aspects of brain function and mediate behavioral and addictive properties of nicotine. Neuronal nAChRs derive from combinations of α and β subunits, whose assembly is tightly regulated. NACHO was recently identified as a chaperone for α7-type nAChRs. Here, we find NACHO mediates assembly of all major classes of presynaptic and postsynaptic nAChR tested. NACHO acts at early intracellular stages of nAChR subunit assembly and then synergizes with RIC-3 for receptor surface expression...

BACKGROUND: Prolonged grief disorder (PGD) causes significant impairment in approximately 7% of bereaved people. Although cognitive-behavioral therapy (CBT) has been shown to effectively treat PGD, there is no evidence of long-term effects of CBT. OBJECTIVE: To determine the long-term efficacies of CBT with exposure or CBT without exposure in treating PGD by assessing outcome at 2 years. METHODS: A randomized controlled trial of PGD patients (N = 80) attending an outpatient clinic took place between September 2007 and June 2010, and a 2-year follow-up occurred between December 2009 and October 2012...

Pattern classification techniques have been widely used to differentiate neural activity associated with different perceptual, attentional, or other cognitive states, often using fMRI, but more recently with EEG as well. Although these methods have identified EEG patterns (i.e., scalp topographies of EEG signals occurring at certain latencies) that decode perceptual and attentional states on a trial-by-trial basis, they have yet to be applied to the spatial scope of attention toward global or local features of the display...

Dopaminergic reward dysfunction in addictive behaviors is well supported in the literature. There is evidence that alterations in synchronous neural activity between brain regions subserving reward and various cognitive functions may significantly contribute to substance-related disorders. This study presents the first evidence showing that a pro-dopaminergic nutraceutical (KB220Z) significantly enhances, above placebo, functional connectivity between reward and cognitive brain areas in the rat. These include the nucleus accumbens, anterior cingulate gyrus, anterior thalamic nuclei, hippocampus, prelimbic and infralimbic loci...

OBJECTIVE: We present a retrospective meta-analysis of voxel-based morphometry (VBM) of gray (GM) and white matter (WM) differences between patients with bipolar disorder (BD) and behaviorally healthy controls. METHODS: We used the activation likelihood estimation and Sleuth software for our meta-analysis, considering P-value maps at the cluster level inference of .05 with uncorrected P<.001. Results were visualized with the software MANGO. RESULTS: We included twenty-five articles in the analysis, and separated the comparisons where BD patients had lower GM or WM concentrations than controls (573 subjects, 21 experiments, and 117 locations/180 subjects, five experiments, and 15 locations, respectively) and the comparisons where BD patients had greater GM concentrations than controls (217 subjects, nine experiments, and 49 locations)...

INTRODUCTION: Stroke is a recognized cause of disability among adults. However the impact that the deficits that occur after a moderate/severe stroke have on long-term disability, as well as the response of the resultant deficits to rehabilitation, are not completely understood. PATIENTS AND METHODS: A total of 396 patients with a modified Rankin score >= 3 after an ischemic (n = 221) or hemorrhagic (n = 175) stroke were included in this study. All patients were assessed with cognitive, behavior, emotional, motor and functional domains...

Approximately half of the human brain is composed of white matter (WM), a specialized tissue housing the axonal projection of neurons and their necessary supporting glial cells. Axons course long distances from their parent soma, have a delicate structure, large surface area and in many cases are dependent upon a uniquely close morphological arrangement with myelinating oligodendrocyte partners; all factors that may predispose them to injury and disease. WM damage is central to a range of well-characterized disorders including multiple sclerosis and spinal cord injury and is also makes a significant contribution to disorders often considered to be largely focused in gray matter; for example, in stroke where ~49% of injury by volume is located in WM...

Oxytocin is a key modulator of emotional processing and social cognitive function. In line with this, polymorphisms of genes involved in oxytocin signaling, like the oxytocin receptor (OXTR) gene, are known to influence social behavior in various species. However, to date, no study has investigated environmental factors possibly influencing the epigenetic variation of the OXTR gene and its behavioral effects in dogs. Pet dogs form individualized and strong relationships with their owners who are central figures in the social environment of their dogs and therefore might influence the methylation levels of their OXTR gene...

Alzheimer's disease (AD) is a terminal, age-related neurological syndrome exhibiting progressive cognitive and memory decline, however AD patients in addition exhibit ancillary neuropsychiatric symptoms (NPSs) and these include aggression. In this communication we provide recent evidence for the mis-regulation of a small family of genes expressed in the human hippocampus that appear to be significantly involved in expression patterns common to both AD and aggression. DNA array- and mRNA transcriptome-based gene expression analysis and candidate gene association and/or genome-wide association studies (CGAS, GWAS) of aggressive attributes in humans have revealed a surprisingly small subset of six brain genes that are also strongly associated with altered gene expression patterns in AD...

BACKGROUND: The home environment is where young children spend most of their time, and is critically important to supporting behaviors that promote health and prevent obesity. However, the home environment and lifestyle patterns remain understudied, and few interventions have investigated parent-led makeovers designed to create home environments that are supportive of optimal child health and healthy child weights. OBJECTIVE: The aim of the HomeStyles randomized controlled trial (RCT) is to determine whether the Web-based HomeStyles intervention enables and motivates parents to shape the weight-related aspects of their home environments and lifestyle behavioral practices (diet, exercise, and sleep) to be more supportive of their preschool children's optimal health and weight...

There is growing interest in the role of the oxytocin system in social cognition and behavior. Peripheral oxytocin concentrations are regularly used to approximate central concentrations in psychiatric research, however, the validity of this approach is unclear. Here we conducted a pre-registered systematic search and meta-analysis of correlations between central and peripheral oxytocin concentrations. A search of databases yielded 17 eligible studies, resulting in a total sample size of 516 participants and subjects...

Acteoside and isoacteoside, two phenylethanoid glycosides, coexist in some plants. This study investigates the memory-improving and cytoprotective effects of acteoside and isoacteoside in amyloid β peptide 1-42 (Aβ 1-42)-infused rats and Aβ 1-42-treated SH-SY5Y cells. It further elucidates the role of amyloid cascade and central neuronal function in these effects. Acteoside and isoacteoside ameliorated cognitive deficits, decreased amyloid deposition, and reversed central cholinergic dysfunction that were caused by Aβ 1-42 in rats...
