This study examined whether increasing autophagy could improve cognitive deficits in hindlimb unloaded (HU) mice, which was used as an animal model of synaptic plasticity impairment. Male C57BL/6 mice were randomly divided into three groups: control, HU and HU + rapamycin groups. Hindlimb unloading treatment was used to establish the animal model for 2 weeks. Rapamycin was intraperitoneally injected at a dose of 0.5 mg/kg/day along with hindlimb unloading procedure. The open field test and the elevated plus maze test showed that rapamycin considerably prevented the level of anxiety and increased exploratory behaviour in HU mice...

Alzheimer's disease (AD) is characterised as a provoked inflammatory response and oxidative stress along with amyloid β peptide (Aβ) deposition and neurofibrillary tangles in the brain, and effective treatment is greatly needed. Molecular hydrogen, which has been proposed to be an antioxidant that selectively reduces reactive oxygen species, was found to exert beneficial effects in Aβ injection-induced cognitive dysfunction. However, whether and how hydrogen affects AD pathogenesis remains uninvestigated...

OBJECTIVE: Whilst the evidence base for cognitive behavioural therapy (CBT) with children and young people is growing, the mechanisms through which these beneficial effects occur are still unclear. This systematic review seeks to appraise the relationship between therapeutic outcomes in CBT and therapist adherence and competence, within the child and adolescent literature. METHOD: A systematic review was carried out, with five studies identified as meeting the inclusion criteria...

RATIONALE: Dysregulation of the serotonin (5-HT) system is a pathophysiological component in major depressive disorder (MDD), a condition closely associated with abnormal emotional responsivity to positive and negative feedback. However, the precise mechanism through which 5-HT tone biases feedback responsivity remains unclear. 5-HT2C receptors (5-HT2CRs) are closely linked with aspects of depressive symptomatology, including abnormalities in reinforcement processes and response to stress...

BACKGROUND: Sleep restriction therapy (SRT) is a largely untested single treatment component of cognitive-behaviour therapy for insomnia. To date, the evidence for contraindications for SRT is limited to very few studies. The present study investigated the objective and subjective daytime consequences during the acute phase of SRT for adults diagnosed with Chronic Insomnia Disorder. METHODS: Sixteen adults (age = 36.3 ± 13.4 yrs, 12 females, 4 males) underwent SRT for their insomnia over a two week period based on recommendations by Miller and colleagues (2014) [6]...

BACKGROUND: Randomized controlled trials (RCTs) are the mainstay of evaluations of the efficacy of psychosocial interventions. In a recent Cochrane systematic review we analysed the efficacy of cognitive behavioural-based psychotherapies compared to treatment as usual (TAU) in adults who self-harm. In this study we examine the content and reporting quality of TAU in these trials and their relationship to outcomes. METHODS: Five electronic databases (CCDANCTR-Studies and References, CENTRAL, MEDLINE, EMBASE, and PsycINFO) were searched for RCTs, indexed between 1 January 1998 and 30 April 2015, of cognitive-behavioural interventions compared to TAU for adults following a recent (within six months) episode of self-harm...

BACKGROUND: Individuals (PE-F1s) born from preeclampsia (PE)-complicated pregnancies have elevated risks for cognitive impairment. Intervals of disturbed maternal plasma angiokines precede clinical signs of PE. We hypothesized pan-blastocyst dysregulation of angiokines underlies altered PE-F1 brain vascular and neurological development. This could alter brain functional connectivity (FC) patterns at rest. MATERIALS AND METHODS: Resting-state functional MRI datasets of ten, matched child pairs (5 boys and 5 girls aged 7-10 years of age) from PE or control pregnancies were available for study...

Cognitive-behavioural models of obsessive-compulsive disorder (OCD) stemmed from knowledge acquired from cognitive science. Researchers continue to apply basic cognitive-affective science methods to understanding OCD, with the overarching goal of improving and refining evidence-based treatments. However, the degree to which such research has contributed to this goal is unclear. We reviewed OCD research in the general areas that comprise basic cognitive science, and evaluated the degree to which it has contributed to our understanding of the development, maintenance, and treatment of OCD...

John D McLennan
The term dual diagnosis can refer to the co-occurrence of an intellectual disability and a mental disorder. While such a term may have some advocacy rationale aimed at facilitating improved mental health care for those with intellectual disabilities, it is proposed that the construct has flawed underpinnings, and its application may problematize mental health service delivery. A core concern is the promotion of categorical diagnostic models, whereas dimensional models may more accurately reflect underlying continuums for both cognitive and mental health challenges...

Combination antiretroviral therapies have revolutionized the treatment of HIV infection, and many patients now enjoy a lifespan equal to that of the general population. However, HIV-associated neurocognitive disorders (HAND) remain a major health concern, with between 30% and 70% of all HIV-infected patients developing cognitive impairments during their life time. One important feature of HAND is visuo-perceptual deficits, but the systems-level neural dynamics underlying these impairments are poorly understood...

Effort-based decision-making is a cognitive process crucial to normal motivated behaviour. Apathy is a common and disabling complication of Parkinson's disease, but its aetiology remains unclear. Intriguingly, the neural substrates associated with apathy also subserve effort-based decision-making in animal models and humans. Furthermore, the dopaminergic system plays a core role in motivating effortful behaviour for reward, and its dysfunction has been proposed to play a crucial role in the aetiology of apathy in Parkinson's disease...

Background : The mechanisms leading from traumatic stress to social, emotional and cognitive impairment and the development of mental illnesses are still undetermined and consequently there remains a critical need to develop therapies for preventing the adverse consequences of traumatic stress. Research indicates nicotinic acetylcholine receptors containing α4 subunits (α4*nAChRs) are both impacted by stress and capable of modulating the stress response. In this study, we investigated whether varenicline, a partial α4β2*nAChR agonist which reduces nicotine, alcohol and sucrose consumption, can reduce stress, a driving factor in substance use disorders...

BACKGROUND: Ethnic minority service users with schizophrenia and schizoaffective disorders may experience inequalities in care. There have been no recent studies assessing access to evidence-based treatments for psychosis amongst the main ethnic minority groups in the UK. METHODS: Data from nationally representative surveys from England and Wales, for 10,512 people with a clinical diagnosis of schizophrenia or schizoaffective disorders, were used for analyses. Multi-level multivariable logistic regression analyses were used to assess ethnic minority inequalities in access to pharmacological treatments, psychological interventions, shared decision making and care planning, taking into account a range of potential confounders...

ISSUE ADDRESSED: Many Australian employees now regularly work from home in some capacity. This new way of working has not been widely studied in relation to the potential implications for employees' health-related behaviour or workplace health promotion. The aim of this study was to explore office-based employees' perceptions of the impact of flexible work on physical activity and sedentary behaviour; and preferences for associated interventions. METHODS: Three focus groups were conducted with office-based employees (n=28) six months after the introduction of a flexible work policy...

Work is undoubtedly fundamental to human life, social development and the economic development of individuals, organizations and nations. However, the experience of working is not always pleasant as there are many instances where relationships between workers could deteriorate, leading to practices and behaviours that could be characterized as workplace bullying and/or mobbing. The current study is an exploratory study which used autoethnography to investigate experiences of academic bullying and mobbing, and relates the practices to power structures in academic institutions...

A careful look at societies facing threat reveals a unique phenomenon in which liberals and conservatives react emotionally and attitudinally in a similar manner, rallying around the conservative flag. Previous research suggests that this rally effect is the result of liberals shifting in their attitudes and emotional responses toward the conservative end. Whereas theories of motivated social cognition provide a motivation-based account of cognitive processes (i.e. attitude shift), it remains unclear whether emotional shifts are, in fact, also a motivation-based process...

BACKGROUND: During the first 4 months of age, approximately 20% of infants cry a lot without an apparent reason. Most research has targeted the crying, but the impact of the crying on parents, and subsequent outcomes, need to receive equal attention. This study reports the findings from a prospective evaluation of a package of materials designed to support the well-being and mental health of parents who judge their infant to be crying excessively. The resulting "Surviving Crying" package comprised a website, printed materials, and programme of Cognitive Behaviour Therapy-based support sessions delivered to parents by a qualified practitioner...
