#1
James B Robinson, Julie Loebach Wetherell
This article describes two case studies using an interdisciplinary intervention for homebound older adults who experience fear of falling, resulting in debility and isolation. The patients discussed received separate home visits from a physical therapist (two and four visits) and psychologist (six and eight visits) and intervention components included an initial assessment of physical ability, prescription of home exercise program, exposure therapy, and cognitive restructuring. Both patients reported satisfaction with the fear of falling intervention and showed improved ability to walk, both in distance and in requiring less assistance...

Hashimoto's encephalopathy (HE) is a rare neurological syndrome characterized by the presence of positive serum antithyroid antibodies, altered mental status, and clinical response to glucocorticoid therapy. Although HE has been documented in the literature from a medical standpoint, reports on the neuropsychological presentation of this syndrome are scarce. This article presents a literature review of cognitive deficits reported in HE cases. In addition, we describe the case of a 76-year-old Russian speaking woman diagnosed with HE in May 2012...

We review current findings associating socioeconomic status (SES), development of neurocognitive functions, and neurobiological pathways. A sizeable interdisciplinary literature was organized through a bifurcated developmental trajectory (BiDeT) framework, an account of the external and internal variables associated with low SES that may lead to difficulties with attention and learning, along with buffers that may protect against negative outcomes. A consistent neurocognitive finding is that low-SES children attend to information nonselectively, and engage in late filtering out of task-irrelevant information...

Accumulated recent research suggests that prior knowledge of multiple languages leads to advantages in learning additional languages. In the current article, we review studies examining potential differences between monolingual and multilingual speakers in novel language learning in an effort to uncover the cognitive mechanisms that underlie such differences. We examine the multilingual advantage in children and adults, across a wide array of languages and learner populations. The majority of this literature focused on vocabulary learning, but studies that address phonology, grammar, and literacy learning are also discussed to provide a comprehensive picture of the way in which multilingualism affects novel language learning...

Among five members of the K(+)-dependent Na(+)/Ca(2+) exchanger (NCKX) family (NCKX1-5), only NCKX2 is highly expressed in mouse brain. NCKX2 in plasma membranes mediates cytosolic calcium excretion through electrogenic exchange of 4 Na(+) for 1 Ca(2+) and 1 K(+). Here, we observed significantly decreased levels of NCKX2 protein and mRNA in the CA1 region of APP23 mice, a model of Alzheimer's disease. We also found that, like APP23 mice, heterozygous NCKX2-mutant mice exhibit mildly impaired hippocampal LTP and memory acquisition, the latter based on novel object recognition and passive avoidance tasks...

INTRODUCTION: Concept map is a useful cognitive tool for enhancing a student's critical thinking (CT) by encouraging students to process information deeply for understanding. However, the evidence regarding its effectiveness on nursing students' CT is contradictory. This paper compares the effectiveness of concept mapping and traditional linear nursing care planning on students' CT. METHODS: An experimental design was used to examine the CT of 60 baccalaureate students who participated in pediatric clinical nursing course in the Shahrekord University of Medical Sciences, Shahrekord, Iran in 2013...

The current study examined the neurochemical mechanisms and neuroanatomical changes underlying co-existing behavioral effects associated with chronic stress-induced alterations in serotonin (5HT) neurons. Chronic unpredictable stress (CUS) to adult male rats produced depression-like changes with cognitive dysfunction and selective cell death in the interfascicular nucleus of the dorsal raphe (DRif) resulting in decreased 5HTergic innervation of medial prefrontal cortex (mPFC). Twenty-one days of CUS decreased basal plasma levels of corticosterone and produced a shorter latency to immobility and longer durations of immobility in the force-swim test that persisted for one month after CUS...

Category learning in animals is typically trained explicitly, in most instances by varying the exemplars of a single category in a matching-to-sample task. Here, we show that male rhesus macaques can learn categories by a transitive inference paradigm in which novel exemplars of five categories were presented throughout training. Instead of requiring decisions about a constant set of repetitively presented stimuli, we studied the macaque's ability to determine the relative order of multiple exemplars of particular stimuli that were rarely repeated...

Dentate gyrus (DG) is widely thought to provide a teaching signal that enables hippocampal encoding of memories, but its role during retrieval is poorly understood. Some data and models suggest that DG plays no role in retrieval; others encourage the opposite conclusion. To resolve this controversy, we evaluated the effects of optogenetic inhibition of dorsal DG during context fear conditioning, recall, generalization, and extinction in male mice. We found that (1) inhibition during training impaired context fear acquisition; (2) inhibition during recall did not impair fear expression in the training context, unless mice had to distinguish between similar feared and neutral contexts; (3) inhibition increased generalization of fear to an unfamiliar context that was similar to a feared one and impaired fear expression in the conditioned context when it was similar to a neutral one; (4) inhibition impaired fear extinction...

The aim of this review is to critically evaluate the effectiveness and candidate mechanisms of action of psychological interventions which aim to either (a) improve the capacity for self-regulatory, reflective processes or (b) reduce the impact of automatic appetitive processes, in an attempt to influence food intake and associated weight-gain. Our aim was to examine three important issues regarding each type of intervention: i) whether the intervention influenced behaviour in the laboratory, ii) whether the intervention influenced behaviour and/or body mass index in the real world, and iii) whether the proposed mechanism of action was supported by evidence...

Recent interest in the lasting effects of early-life stress has expanded to include effects on cognitive performance. An increase in circulating glucocorticoids is induced by stress exposure and glucocorticoid effects on the hippocampus likely underlie many of the cognitive consequences. Here we review studies showing that corticosterone administered to young rats at the conclusion of the stress-hyporesponsiveness period affects later performance in hippocampally-mediated trace eyeblink conditioning. The nature and even direction of these effects varies with the elevation patterns (level, duration, temporal fluctuation) achieved by different administration methods...

BACKGROUND: Mobility scooters can facilitate community participation among individuals with mobility limitations. However, accidents are a serious concern with scooter use. Scooter training has been recommended to improve safety, but there are currently few validated programs available. Therefore, we developed a Systematic, Comprehensive, One-to-One Training (SCOOT) program for scooter users. We will conduct a study to evaluate the outcomes produced by the provision SCOOT. METHODS: This feasibility study will use a mixed-methods, rater-blinded, randomized control trial, with a two-step wedge design...

OBJECTIVE: The question whether musical training is associated with enhanced auditory and cognitive abilities in children is of considerable interest. In the present study, we compared children with music training versus those without music training across a range of auditory and cognitive measures, including the ability to detect implicitly statistical regularities in input (statistical learning). METHODS: Statistical learning of regularities embedded in auditory and visual stimuli was measured in musically trained and age-matched untrained children between the ages of 9-11years...

Type II diabetes mellitus (DM) is associated with increased risk of dementia; however, few studies have examined the longitudinal association between DM and cognitive outcomes in large nationally representative cohorts. We investigated these associations in 7605 participants enrolled in the National Health and Aging Trends Study, a nationally representative prospective study of Medicare beneficiaries ≥65, from 2011 to 2015. Participants or proxy respondents reported DM and dementia diagnosis, and participants completed immediate and delayed recall word list learning tests and the Clock Drawing Test...

Conditions experienced early in life can shape brain development and later cognition. Altricial songbirds are particularly vulnerable to early environmental perturbations. Research on "Developmental Stress" in songbirds has addressed how early-life conditions may impair song learning and has been extended to consider other components of adult phenotype. Early-life challenges ranging from ectoparasites to competition with siblings have been shown to compromise song learning and other measures of cognition, as well as behavioral strategy...

The hyperphosphorylation of tau in the hippocampus can be caused by central and peripheral insulin resistance and these alterations are related to the development of tauopathies, such as Alzheimer's disease. In this study, we used a high-fat diet to induce obesity and insulin resistance in adult Swiss mice and checked whether supplementation with Myrciaria jaboticaba berry peel for 10 weeks could improve insulin sensitivity, learning/memory performance and prevent tau phosphorylation in the hippocampus. Furthermore, adipocytokines, inflammatory markers, and oxidative stress were assessed...

BACKGROUND: Descending pain inhibition suppresses spinal nociception, reducing nociceptive input to the brain. It is modulated by cognitive and emotional processes. In subjects with chronic pain, it is impaired, possibly contributing to pain persistence. A previously developed feedback method trains subjects to activate their descending inhibition. Participants are trained to use cognitive-emotional strategies to reduce their spinal nociception, as quantified by the nociceptive flexor reflex (RIII reflex), under visual feedback about their RIII reflex size...

AIM: To characterize the phenotypic profile of a cohort of children affected with CLN5, a rare form of neuronal ceroid-lipofuscinosis (NCL), and to trace the features of the natural history of the disease. METHOD: Records of 15 children (nine males, six females) were obtained from the data sets of the DEM-CHILD International NCL Registry. Disease progression was measured by rating six functional domains at different time points along the disease course. All patients underwent mutation analysis of the CLN5 gene and ultrastructural investigations of peripheral tissues...
