Brittney Yegla, Vinay Parikh
Basal forebrain (BF) cholinergic neurons innervating the cortex regulate cognitive, specifically attentional, processes. Cholinergic atrophy and cognitive decline occur at an accelerated pace in age-related neurodegenerative disorders such as Alzheimer's disease; however, the mechanism responsible for this phenomenon remains unknown. Here we hypothesized that developmental suppression of nerve growth factor signaling, mediated via tropomyosin-related kinase A (trkA) receptors, would escalate age-related attentional vulnerability...

Young adult cancer patients (YACPs), aged 18-35 years when diagnosed with cancer, are in a vulnerable transitioning period from adolescence to adulthood, where cancer adds a tremendous burden. However, YACPs' challenges and coping strategies are under-researched. The objective of this study was to explore what challenges YACP experience during their treatment, and what coping strategies they applied to them. We conducted a qualitative study with a phenomenological-hermeneutic design, including retrospective, semi-structured interviews of 16 YACPs who had undergone cancer treatment...

BACKGROUND: Lifestyle has previously been associated with the onset of Alzheimer's disease (AD) in the typically developing population, but research investigating this association in Down syndrome (DS) is limited. METHOD: Adults with DS and AD (n = 27) were compared to adults with DS without AD (n = 30) on physical activity, diet, weight, where participants currently lived, where participants had lived for the majority of their lives, educational attainment, occupational attainment and cognitive activity...

REVIEW
Larry D Reid, Faith E Avens, Alicia A Walf
This review provides the rationale for implementing cognitive behavioral therapy (CBT) for the prevention of Alzheimer's disease (AD). There are known risk factors associated with the development of AD, some of which may be ameliorated with CBT. We posit that treating the risk factors of inactivity, poor diet, hyposmia and anosmia, sleep disorders and lack of regularly engaged challenging cognitive activity will modify the physiology of the brain sufficiently to avoid the accumulation of excess proteins, including amyloid beta, causal events in the development of AD...

According to the embodied cognition perspective, cognitive systems and perceptuo-motor systems are deeply intertwined and exert a causal effect on each other. A prediction following from this idea is that cognitive activity can result in subtle changes in observable movement. In one experiment, we tested whether reading various sentences resulted in changes in postural sway. Sentences symbolized various human activities involving high, low, or no physical effort. Dutch participants stood upright on a force plate, measuring the body center of pressure, while reading a succession of sentences...

Previous functional magnetic resonance imaging (fMRI) investigations suggest that the intrinsically organized large-scale networks and the interaction between them might be crucial for cognitive activities. A triple network model, which consists of the default-mode network, salience network, and central-executive network, has been recently used to understand the connectivity patterns of the cognitively normal brains versus the brains with disorders. This model suggests that the salience network dynamically controls the default-mode and central-executive networks in healthy young individuals...

An improved understanding of how the brain allocates mental resources as a function of task difficulty is critical for enhancing human performance. Functional near infrared spectroscopy (fNIRS) is a field-deployable optical brain monitoring technology that provides a direct measure of cerebral blood flow in response to cognitive activity. We found that fNIRS was sensitive to variations in task difficulty in both real-life (flight simulator) and laboratory settings (tests measuring executive functions), showing increased concentration of oxygenated hemoglobin (HbO2) and decreased concentration of deoxygenated hemoglobin (HHb) in the prefrontal cortex as the tasks became more complex...

INTRODUCTION: Rest until symptom-free, followed by a progressive stepwise return to activities, is often prescribed in the management of paediatric concussions. Recent evidence suggests prolonged rest may hinder recovery, and early resumption of physical activity may be associated with more rapid recovery postconcussion. The primary objective is to determine whether the early reintroduction of non-contact physical activity beginning 72 hours postinjury reduces postconcussive symptoms at 2 weeks in children following an acute concussion as compared with a rest until asymptomatic protocol...

INTRODUCTION: Rumination, cognitive control deficits, cognitive saturation, and loss of inhibition are the major hypotheses used to explain depressive disorders. A few studies have nevertheless looked at the form of thought. In this study, we will test a double measurement of the number of thoughts and a double measurement of the flow of thought together with their correlation with well-being, mental pain, and depression. MATERIAL AND METHODS: Between May and September 2015, 68 subjects, initially admitted as emergencies for acute anxiety depressive disorders and/or suicide attempts and subsequently monitored as post-emergency outpatients in medico-psychological consultations agreed to complete a set of Visual Analogue Scales measuring their well-being, their mental pain, their estimated number of thoughts and the how agitated these thoughts are estimated to be...

OBJECTIVES: Cognitive impairment (CI) is a common and potentially debilitating component of the disease course in multiple sclerosis (MS). However, therapeutic options remain limited. It is unknown whether cognitively enriching activities reduce the burden of CI in patients with MS, as is found in other neurologic diseases affecting cognition. The aim of this study was to determine whether participation in cognitively enriching activities decreased self-reported CI in MS patients. METHODS: CI and activity levels were reported through electronic surveys completed by MS patients at the Cleveland Clinic...

Genetic susceptibility contributes to the etiology of sporadic Parkinson's Disease (PD) and worldwide studies have found positive associations of polymorphisms in the alpha-synuclein gene (SNCA) with the risk for PD. However, little is known about the influence of variants of SNCA in individual traits or phenotypical aspects of PD. Further, there is a lack of studies with Latin-American samples. We evaluated the association between SNCA single nucleotide polymorphisms (single nucleotide polymorphisms, SNPs - rs2583988, rs356219, rs2736990, and rs11931074) and PD risk in a Brazilians sample...

BACKGROUND: There are no disease-modifying treatments for dementia. There is also no consensus on disease modifying outcomes. We aimed to produce the first evidence-based consensus on core outcome measures for trials of disease modification in mild-to-moderate dementia. METHODS AND FINDINGS: We defined disease-modification interventions as those aiming to change the underlying pathology. We systematically searched electronic databases and previous systematic reviews for published and ongoing trials of disease-modifying treatments in mild-to-moderate dementia...

OBJECTIVE: Caregivers usually are not involved while planning the stroke survivor's medical and rehabilitation goals and interventions. This review aimed to identify the needs of stroke survivors as perceived by their caregivers. DESIGN: A literature search from 2003 to 2014 was conducted using Medline, CINAHL, PsychINFO, and Google Scholar. Sixty-six studies were included. Most studies excluded did not encompass caregivers' perspectives. Four reviewers screened the titles, abstracts, and full texts of the articles for inclusion...

Long distance migratory birds find their way by sensing and integrating information from a large number of cues in their environment. These cues are essential to navigate over thousands of kilometers and reach the same breeding, stopover, and wintering sites every year. The semipalmated sandpiper (Calidris pusilla) is a long-distance migrant that breeds in the arctic tundra of Canada and Alaska and winters on the northeast coast of South America. Its fall migration includes a 5,300-kilometer nonstop flight over the Atlantic Ocean...

The Environmental Noise Directive expects residents to be actively involved in localising and selecting noise abatement interventions during the noise action planning process. Its intervention impact is meant to be homogeneous across population groups. Against the background of social heterogeneity and environmental disparities, however, the impact of noise action planning on exposure to traffic-related noise and its health effects is unlikely to follow homogenous distributions. Until now, there has been no study evaluating the impact of noise action measures on the social distribution of traffic-related noise exposure and health outcomes...

BACKGROUND: It remains unclear so far whether the role of cognitive reserve may differ between physically frail compared to less frail individuals. Therefore, the present study set out to investigate the relation of key markers of cognitive reserve to cognitive status in old age and its interplay with physical frailty in a large sample of older adults. METHODS: We assessed Mini-Mental State Examination (MMSE) in 701 older adults. We measured grip strength as indicator of physical frailty and interviewed individuals on their education, past occupation, and cognitive leisure activity...

Miroslaw Wyczesany, Tomasz S Ligeza
Reappraisal is an emotion regulation strategy which involves changing the interpretation of emotional stimuli. It decreases measures of negative affect together with markers of emotional processing, including late positive potential (LPP). Affective responses can also be attenuated by various cognitive tasks. As reappraisal tasks require cognitive effort to elaborate emotional stimuli, it is possible that the observed reduction of the LPP amplitude during reinterpretation is, at least partly, caused by an unspecific cognitive activity...

Case-based reasoning and data interpretation is an artificial intelligence approach that capitalizes on past experience to solve current problems and this can be used as a method for practical intelligent systems. Case-based data reasoning is able to provide decision support for experts and clinicians in health systems as well as lifestyle systems. In this project we were focusing on developing a solution for healthy ageing considering daily activities, nutrition as well as cognitive activities. The data analysis of the reasoner followed state of the art guidelines from clinical practice...
