Jun Zhang, Mingxia Liu, Le An, Yaozong Gao, Dinggang Shen
Structural magnetic resonance imaging (MRI) has been proven to be an effective tool for Alzheimer's disease (AD) diagnosis. While conventional MRI-based AD diagnosis typically uses images acquired at a single time point, a longitudinal study is more sensitive in detecting early pathological changes of AD, making it more favorable for accurate diagnosis. In general, there are two challenges faced in MRI-based diagnosis. First, extracting features from structural MR images requires timeconsuming nonlinear registration and tissue segmentation, whereas the longitudinal study with involvement of more scans further exacerbates the computational costs...

Mild Cognitive Impairment is a preclinical stage of Alzheimer's disease (AD). For effective treatment of AD, it is important to identify MCI patients who are at a high risk of developing AD over the course of time. İn this study, autoregressive modelling of multiple heterogeneous predictors of Alzheimer's dısease is performed to capture their evolution over time. The models are trained using three different arrangements of longitudinal data. These models are then used to estimate future biomarker readings of individual test subjects...

BACKGROUND: Currently, there are no concrete, evidence-based default procedures to adequately assess the capacity to consent to medical treatment. This explains why different raters use individual heuristics, differing both within and between disciplines. The lack of a procedure that is standardized, validated, and equally accepted across disciplines to assess the capacity to consent to treatment has led to an uncertainty in legal and medical practice regarding appropriate action and decision making...

[Purpose] The purpose of this study was to investigate the effects of taekwondo training on cognitive function and academic self-efficacy in children. [Subjects and Methods] Thirty-five children participated in the study. Seventeen children were randomly selected to undergo taekwondo training for 16 weeks (5 times per week). As controls, 18 children received no training. Cognitive function and academic self-efficacy were measured using the Stroop Color and Word Test (Word, Color, and Color-Word) and academic self-efficacy scale (Self-confidence, Self-regulatory Efficacy, and Task Difficulty Preference), respectively...

Intolerance of uncertainty (IU) is an important transdiagnostic variable within various anxiety and mood disorders. Theory suggests that individuals high in IU interpret ambiguous information in a more threatening manner. A parallel line of research has shown that interpretive biases can be modified through cognitive training and previous research aimed at modifying negative interpretations through Cognitive Bias Modification (CBM-I) has yielded promising results. Despite these findings, no research to date has examined the efficacy of an IU-focused CBM-I paradigm...

PURPOSE: There is growing evidence of significant harmful effects of loneliness. Relatively little work has focused on how best to reduce loneliness in people with mental health problems. We aim to present an overview of the current state of the art in loneliness interventions in people with mental health problems, identify relevant challenges, and highlight priorities for future research and implementation. METHODS: A scoping review of the published and grey literature was conducted, as well as discussions with relevant experts, to propose a broad classification system for types of interventions targeting loneliness...

While previous attempts to train self-control in humans have frequently failed, we set out to train response inhibition using computer-game elements. We trained older adults with a newly developed game-based inhibition training on a tablet for two months and compared them to an active and passive control group. Behavioural effects reflected in shorter stop signal response times that were observed only in the inhibition-training group. This was accompanied by structural growth in cortical thickness of right inferior frontal gyrus (rIFG) triangularis, a brain region that has been associated with response inhibition...

Heikki Tanila
Testing of cognitive functions in rodent disease models constitutes a substantial sector of behavioral neuroscience. It is most often needed in phenotyping genetically modified new rodent (usually mouse) lines or in preclinical testing of cognitive effects of new CNS drugs. This review concerns present pitfalls and future perspectives in this large field, with an emphasis on memory testing in CNS disease models and their preclinical drug testing. It is important to realize that no behavioral test is specific for a single cognitive domain...

BACKGROUND: Posttraumatic stress disorder (PTSD) is a stress disorder characterized by unwanted intrusive re-experiencing of an acutely distressing, often life-threatening, event, combined with symptoms of hyperarousal, avoidance, as well as negative thoughts and feelings. Evidence-based psychological interventions have been developed to treat these symptoms and reduce distress, the majority of which were designed to be delivered face-to-face with trained therapists. However, new developments in the use of technology to supplement and extend health care have led to the creation of e-Mental Health interventions...

Humans and other species have biologically endowed abilities for discriminating quantities. A widely accepted view sees such abilities as an evolved capacity specific for number and arithmetic. This view, however, is based on an implicit teleological rationale, builds on inaccurate conceptions of biological evolution, downplays human data from non-industrialized cultures, overinterprets results from trained animals, and is enabled by loose terminology that facilitates teleological argumentation.

Cognitive training designed to recalibrate maladaptive aspects of cognitive-affective processing associated with the presence of emotional disorder can deliver clinical benefits. This study examined the ability of an integrated training in self-distancing and perspective broadening (SD-PB) with respect to distressing experiences to deliver such benefits in individuals with a history of recurrent depression (≥3 prior episodes), currently in remission. Relative to an overcoming avoidance (OA) control condition, SD-PB: a) reduced distress to upsetting memories and to newly encountered events, both during training when explicitly instructed to apply SD-PB techniques, and after-training in the absence of explicit instructions; b) enhanced capacity to self-distance from and broaden perspectives on participants' experiences; c) reduced residual symptoms of depression...

CONTEXT: The ability to carry out prompt and effective error disclosure has been described in the literature as an essential skill among physicians that can lead to improved patient satisfaction, staff well-being and hospital outcomes. However, few studies have addressed the social psychology principles that may influence physician behaviour. METHODS: The authors provide an overview of recent administrative measures designed to encourage physicians to disclose error, but note that deliberate practice, buttressed with lessons from social psychology, is needed to implement further productive behavioural changes...

INTRODUCTION: Prior studies have demonstrated training-induced changes in the healthy adult brain. Yet, it remains unclear how the injured brain responds to cognitive training months-to-years after injury. METHODS: Sixty individuals with chronic traumatic brain injury (TBI) were randomized into either strategy-based (N = 31) or knowledge-based (N = 29) training for 8 weeks. We measured cortical thickness and resting-state functional connectivity (rsFC) before training, immediately posttraining, and 3 months posttraining...

The music of Richard Wagner tends to generate very diverse judgments indicative of the complex relationship between listeners and the sophisticated musical structures in Wagner's music. This paper presents findings from two listening experiments using the music from Wagner's Der Ring des Nibelungen that explores musical as well as individual listener parameters to better understand how listeners are able to hear leitmotives, a compositional device closely associated with Wagner's music. Results confirm findings from a previous experiment showing that specific expertise with Wagner's music can account for a greater portion of the variance in an individual's ability to recognize and remember musical material compared to measures of generic musical training...
