The need to find measures that reliably predict the onset of epilepsy after injurious events or how the patient will respond to anti-seizure drugs led to intensive pre-clinical and clinical research to discover non-invasive biomarkers that could increase the sensitivity of existing clinical indicators. The use of experimental models of epileptogenesis and of drug-resistance is instrumental to select the most promising approaches to explore such biomarkers in the pre-clinical setting for further clinical validation...

Our goal was to apply a statistical approach to allow the identification of atypical language patterns and to differentiate patients with epilepsy from healthy subjects, based on their cerebral activity, as assessed by functional MRI (fMRI). Patients with focal epilepsy show reorganization or plasticity of brain networks involved in cognitive functions, inducing 'atypical' (compared to 'typical' in healthy people) brain profiles. Moreover, some of these patients suffer from drug-resistant epilepsy, and they undergo surgery to stop seizures...

Transfer is a desired outcome of simulation-based training, yet evidence for how instructional design features promote transfer is lacking. In clinical reasoning, transfer is improved when trainees experience instruction integrating basic science explanations with clinical signs and symptoms. To test whether integrated instruction has similar effects in procedural skills (i.e., psychomotor skills) training, we studied the impact of instruction that integrates conceptual (why) and procedural (how) knowledge on the retention and transfer of simulation-based lumbar puncture (LP) skill...

REVIEW
Patricia Tsui, Andrew Deptula, Derek Y Yuan
PURPOSE OF REVIEW: This paper examines the overlap of conversion disorder with chronic pain conditions, describes ways to assess for conversion disorder, and provides an overview of evidence-based treatments for conversion disorder and chronic pain, with a focus on conversion symptoms. RECENT FINDINGS: Conversion disorder is a significant problem that warrants further study, given that there are not many well-established guidelines. Accurate and timely assessment should help move treatment in a more fruitful direction and avoid unnecessary medical interventions...

BACKGROUND: Deficits in cognitive domains, in particular, those related to the prefrontal cortex, contribute to diminished walking performance in complex conditions in older age. Studies using functional near infra-red spectroscopy (fNIRS) reported inconsistent findings of brain activation age-related changes in response to increased task demands. We aimed to study the effects of aging on gait and prefrontal activation in complex walking tasks with internal and external task demands. METHODS: Twenty-three healthy young adults (30...

The range of stimuli provided by physical space, toys and care practices contributes to the motor, cognitive and social development of children. However, assessing the quality of child education environments is a challenge, and can be considered a health promotion initiative. This study investigated the validity of the criterion, content, construct and reliability of the Affordances in the Home Environment for Motor Development - Infant Scale (AHEMD-IS), version 3-18 months, for the use in daycare settings...

Infant-parent interactions occur across many situations, yet most home-based assessments of parenting behaviors are conducted under conditions of low stress, such as free play. In this study, low-income mothers from the Early Head Start Research and Evaluation Project were observed at home interacting with their 14-month-olds in the mildly stressful "High Chair" assessment (n=1718 dyads). This methodological study tested whether High Chair maternal responsiveness and detachment predicted later toddler cognitive and emotion outcomes, over and above equivalent maternal predictors during free play...

Patients with musculoskeletal illness often report that pain interferes with their ability to engage in activities of daily living. Catastrophic thinking is consistently depicted as an important cognitive factor that hinders adjustment to pain. Current research has also shown that pain negatively impacts an individual's ability to maintain attention on the task at hand. While a measure of the experience of cognitive intrusion of pain (ECIP) has been recently developed to quantify the extent of that impact, little research has explored this issue in everyday settings...

OBJECTIVE: The Human Immunodeficiency Virus (HIV) has an impact on the brain, even when the infection is well-controlled with modern highly-active antiretroviral therapy (HAART). While dementia is rare in those on HAART, milder cognitive impairment is common. The causes, patterns, and evolution of brain dysfunction in people living with HIV remain uncertain. We evaluate whether electrophysiological methods provide informative measures of brain dysfunction in this population. METHODS: A systematic literature search identified studies that used EEG or MEG to evaluate persons living with HIV published between 1996 (when HAART became available) and 2016...

Clancy Blair, Daniel J Berry
Lab-based experimental studies with humans and in animal models demonstrate that the relation between glucocorticoid (GC) levels and performance on measures of higher-order cognitive ability such as executive function (EF) is best described by an inverted U-shape curve. Moderate levels of GCs (cortisol/corticosterone) are associated with comparatively better performance relative to GC levels that are particularly high or low. Although findings from experimental studies are definitive and have high internal validity, the external validity of this association as an aspect of children's development is unknown...

Compensatory Health Beliefs (CHBs), defined as beliefs that an unhealthy behavior can be compensated for by engaging in another healthy behavior, are assumed to hinder health behavior change. The aim of the present study was to investigate the role of CHBs for two distinct eating behaviors (increased fruit and vegetable consumption and eating fewer unhealthy snacks) with a mixed method approach. Participants (N = 232, mean age = 27.3 years, 76.3% women) were randomly assigned to a fruit and vegetable or an unhealthy snack condition...

High altitude cerebral edema (HACE) is a life-threatening illness that develops during the rapid ascent to high altitudes, but its underlying mechanisms remain unclear. Growing evidence has implicated inflammation in the susceptibility to and development of brain edema. In the present study, we investigated the inflammatory response and its roles in HACE in mice following high altitude hypoxic injury. We report that acute hypobaric hypoxia induced a slight inflammatory response or brain edema within 24 h in mice...

BACKGROUND: Cognitive impairment and dementia are associated with a range of cardiovascular conditions including hypertension, coronary artery disease and atrial fibrillation. We aimed to describe the association with heart failure, summarising published data to give estimates around prevalence, incidence and relative risk of cognitive impairment/dementia in heart failure. METHODS: We searched multidisciplinary databases including MEDLINE (OVID), EMBASE (OVID), CINAHL (EBSCO), PsychINFO (EBSCO), Web of Science (Thomson Reuters) and CENTRAL (Cochrane Library) from inception until 31(st) May 2015...

REVIEW
Chantal Chavoix, Ricardo Insausti
Accurate self-awareness is essential for adapting one's behaviour to one's actual abilities, to avoid risky behaviour. Impaired self-awareness of deficits is common in neurodegenerative diseases. Numerous studies show an involvement of midline cortical areas in impaired self-awareness. Among the other brain regions implicated stand the medial temporal lobe (MTL) structures (i.e. hippocampus, amygdala, and temporopolar, entorhinal, perirhinal and posterior parahippocampal cortices). This review aims at evaluating the role of those structures in self-awareness in neurodegenerative diseases...

Brain glucose metabolism is altered in sporadic Alzheimer's disease (sAD), whose pathologies are reproduced in rodents by intracerebroventricular (icv) infusion of streptozotocin (STZ) in subdiabetogenic doses. The icv-STZ model also culminates in central cholinergic dysfunctions, which in turn are known to underlie both the sAD cognitive decline, and synaptic plasticity impairments. Considering the cognitive-enhancing potential of chronic nicotine (Nic), we investigated whether it attenuates icv-STZ-induced impairments in recognition memory and synaptic plasticity in a cognition-relevant substrate: the hippocampal CA1-medial prefrontal cortex (mPFC) pathway...

OBJECTIVE: This study investigated how cognitive function changes with age and whether rates of decline vary by sex or education in a large, homogenous longitudinal cohort characterized by high participation rates, long duration of follow-up, and minimal loss to follow-up. DESIGN/SETTING/PARTICIPANTS: Between 1988 and 2016, 2,225 community-dwelling participants of the Rancho Bernardo Study, aged 31 to 99 years at their initial cognitive assessment, completed neuropsychological testing approximately every 4 years, over a maximum 27-year follow-up...

The MATRICS Consensus Cognitive Battery (MCCB) was developed to assess cognitive treatment effects in schizophrenia clinical trials, and is considered the FDA gold standard outcome measure for that purpose. The aim of the present study was to establish pre-treatment psychometric characteristics of the MCCB in a large pooled sample. The dataset included 2616 stable schizophrenia patients enrolled in 15 different clinical trials between 2007 and 2016 within the United States (94%) and Canada (6%). The MCCB was administered twice prior to the initiation of treatment in 1908 patients...

It has been shown that the metabotropic glutamate receptor subtype 5 (mGluR5) is functionally associated with the NMDA subtype of the glutamate receptor family (NMDA receptors). These two receptors colocalize in brain regions associated with schizophrenia. Although the role of the NMDA receptor in cognitive and negative symptoms of schizophrenia is well studied, information about the role of mGluR5 receptors in schizophrenia is sparse. In our work, we show that subchronic administration of ketamine, a well-studied, non-competitive antagonist of NMDA receptors, caused cognitive deficits in rats as shown by testing novel object recognition (NOR)...

When considering barriers to chronic pain treatment, there is a need to deliver nonpharmacological therapies in a way that is accessible to all individuals who may benefit. To conduct feasibility testing using a guided, Internet-based intervention for individuals with chronic pain, a novel, Internet-based, chronic pain intervention (ICPI) was developed, using concepts proven effective in face-to-face interventions. This study was designed to assess usability of the ICPI and feasibility of conducting larger-scale research, and to collect preliminary data on effectiveness of the intervention...
