Factors Associated With Return to Activity After Concussion Among Female Service Academy Members: Findings From the NCAA-DoD CARE Consortium.

Introduction: Service academy members are at high risk for concussions as a result of participation in both sports and military-specific training activities. Approximately 17% of active duty service members are female, and they face unique challenges in achieving timely recovery from concussions. Understanding the unique characteristics affecting return to unrestricted activity (RTA) among female service academy members is imperative for the ever-growing proportion of females across the U.

Sex Differences in Recovery Trajectories of Assessments for Sport-Related Concussion Among NCAA Athletes: A CARE Consortium Study.

Objectives: The purpose of this study was to determine sex differences in recovery trajectories of assessments for sport-related concussion using Concussion Assessment, Research and Education (CARE) Consortium data.

Methods: National Collegiate Athletic Association athletes (N = 906; 61% female) from sex-comparable sports completed a pre-season baseline assessment and post-sport-related concussion assessments within 6 h of injury, 24-48 h, when they initiated their return to play progression, when they were cleared for unrestricted return to play, and 6 months post-injury. Assessments included the Standardized Assessment of Concussion, Balance Error Scoring System, Brief Symptom Inventory-18, Immediate Post-concussion Assessment and Cognitive Testing (ImPACT), Sport Concussion Assessment Tool-3 symptom evaluation, Clinical Reaction Time, King-Devick test, Vestibular Ocular Motor Screen, 12-item Short-Form Health Survey, Hospital Anxiety and Depression Scale, and Satisfaction with Life Scale.

Initial Mild Traumatic Brain Injury Characteristics and Recovery Patterns Among Females Across the United States Military Service Academies: A Report from the NCAA-DoD CARE Consortium.

Mild traumatic brain injury (mTBI) has been described in the United States (US) military service academy cadet population, but female-specific characteristics and recovery outcomes are poorly characterized despite sex being a confounder. Our objective was to describe female cadets' initial characteristics, assessment performance, and return-to-activity outcomes post-mTBI. Female cadets (n = 472) from the four US military service academies who experienced a mTBI completed standardized mTBI assessments from pre-injury to acute initial injury and unrestricted return-to-duty (uRTD).

Baseline Predictors of Response to Repetitive Task Practice in Chronic Stroke.

Background: Repetitive task practice reduces mean upper extremity motor impairment in of patients with chronic stroke, but response is highly variable. A method to predict meaningful reduction in impairment in response to training based on biomarkers and other data collected prior to an intervention is needed to establish realistic rehabilitation goals and to effectively allocate resources.

Objectives: To identify prognostic factors and better understand the biological substrate for reductions in arm impairment in response to repetitive task practice among patients with chronic (≥6 months) post-stroke hemiparesis.

Contraction Phase and Force Differentially Change Motor Evoked Potential Recruitment Slope and Interhemispheric Inhibition in Young Versus Old.

Interhemispheric interactions are important for arm coordination and hemispheric specialization. Unilateral voluntary static contraction is known to increase bilateral corticospinal motor evoked potential (MEP) amplitude. It is unknown how increasing and decreasing contraction affect the opposite limb.

The ENIGMA Stroke Recovery Working Group: Big data neuroimaging to study brain-behavior relationships after stroke.

The goal of the Enhancing Neuroimaging Genetics through Meta-Analysis (ENIGMA) Stroke Recovery working group is to understand brain and behavior relationships using well-powered meta- and mega-analytic approaches. ENIGMA Stroke Recovery has data from over 2,100 stroke patients collected across 39 research studies and 10 countries around the world, comprising the largest multisite retrospective stroke data collaboration to date. This article outlines the efforts taken by the ENIGMA Stroke Recovery working group to develop neuroinformatics protocols and methods to manage multisite stroke brain magnetic resonance imaging, behavioral and demographics data.

Methods for an Investigation of Neurophysiological and Kinematic Predictors of Response to Upper Extremity Repetitive Task Practice in Chronic Stroke.

Objective: To demonstrate the feasibility of algorithmic prediction using a model of baseline arm movement, genetic factors, demographic characteristics, and multimodal assessment of the structure and function of motor pathways. To identify prognostic factors and the biological substrate for reductions in arm impairment in response to repetitive task practice.

Design: This prospective single-group interventional study seeks to predict response to a repetitive task practice program using an intent-to-treat paradigm.

Emotional Intelligence in Incarcerated Female Offenders With Psychopathic Traits.

Emotional impairment is a core feature of psychopathy, and the disorder has been linked to an inability to recognize and regulate emotion, leading to deficiencies in empathy and difficulties in social functioning. This study investigated associations among psychopathic traits and ability-based emotional intelligence (EI) in female offenders and integrated data with previously published male offender data (Ermer, Kahn, Salovey, & Kiehl, 2012) to examine gender differences in relationships. Results showed that female offenders were impaired in the understanding and management of emotion relative to the general population, and that female offenders scored higher than male offenders in EI.

Why do people think that others should earn this or that?

Some questions, such as when a statistical distribution of incomes becomes too unequal, seem highly attention-grabbing, inferentially productive, and morally vexing. Yet many other questions that are crucial to the functioning of a modern economy seem uninteresting non-issues. An evolutionary-psychological framework to study folk-economic beliefs has the potential to illuminate this puzzle.

Conditional Reasoning in Schizophrenic Patients.

Conditional reasoning (if p then q) is used very frequently in everyday situations. Conditional reasoning is impaired in brain-lesion patients, psychopathy, alcoholism, and polydrug dependence. Many neurocognitive deficits have also been described in schizophrenia.

Cross-cultural regularities in the cognitive architecture of pride.

Pride occurs in every known culture, appears early in development, is reliably triggered by achievements and formidability, and causes a characteristic display that is recognized everywhere. Here, we evaluate the theory that pride evolved to guide decisions relevant to pursuing actions that enhance valuation and respect for a person in the minds of others. By hypothesis, pride is a neurocomputational program tailored by selection to orchestrate cognition and behavior in the service of: () motivating the cost-effective pursuit of courses of action that would increase others' valuations and respect of the individual, () motivating the advertisement of acts or characteristics whose recognition by others would lead them to enhance their evaluations of the individual, and () mobilizing the individual to take advantage of the resulting enhanced social landscape.

Emotional Intelligence and Callous-Unemotional Traits in Incarcerated Adolescents.

Emotional intelligence (EI) is the ability to perceive, manage, and reason about emotions and to use this information to guide thinking and behavior adaptively. Youth with callous-unemotional (CU) traits demonstrate a variety of affective deficits, including impairment in recognition of emotion and reduced emotional responsiveness to distress or pain in others. We examined the association between ability EI and CU traits in a sample of incarcerated adolescents (n = 141) using an expert-rater device (Psychopathy Checklist Youth Version (PCL-YV; Manual for the Hare psychopathy checklist: Youth version.

Decoding of nonverbal language in alcoholism: A perception or a labeling problem?

Alcohol-dependent patients have difficulty recognizing social cues such as emotional facial expressions, prosody, and postures. However, most researchers describing these difficulties rely on labeling tasks. It therefore remains difficult to disentangle genuine emotion-decoding problems from emotion-labeling impairments.

Impaired non-verbal emotion processing in Pathological Gamblers.

Impaired perception of emotion in others has been described and confirmed in addictions with substances, but no such data exists regarding addictions without substances. As it has been hypothesized that toxic effect of substances on the brain was responsible for the impairments described, studying addictions without substances could be of interest to confirm this hypothesis. Twenty-two male pathological gamblers were compared to 22 male healthy controls matched for age and education level on non-verbal emotion perception tasks including faces, voices, and musical excerpts.

Paralimbic biomarkers in taxometric analyses of psychopathy: does changing the indicators change the conclusion?

Although psychopathy has consistently been shown to distribute as a dimension, all prior studies have examined behavioral indicators that may be phenotypically distant from core biological correlates of the syndrome. The current studies attempted to determine whether biomarkers from a high-resolution structural MRI scan of selected limbic and paralimbic structures identified the latent structure of psychopathy as continuous. Participants were 254 adult male medium/maximum security inmates (Study 1) and 191 adolescent male maximum security inmates (Study 2) who volunteered to undergo research MRI scans.

Paralimbic gray matter reductions in incarcerated adolescent females with psychopathic traits.

Psychopathy-related paralimbic and limbic structural brain abnormalities have been implicated in incarcerated adult and adolescent male samples. However, there have been few neuroimaging studies of psychopathic traits in females in general and no studies from incarcerated female youth in particular. Here we present the first study to examine the relationship between brain gray matter volumes and psychopathic traits (assessed using the Psychopathy Checklist-Youth Version [PCL-YV]) in a sample of maximum-security incarcerated female adolescents (N = 39; mean age = 17.

Unfairness sensitivity and social decision-making in individuals with alcohol dependence: a preliminary study.

Background: Altruistic punishment is an evolutionary-based mechanism aimed at maximizing the probability of reciprocity in cooperative exchanges, through the deterrence of non-cooperators. In economic games, humans will often punish others for non-cooperation, even if this punishment is costly to the self. For instance, in the Ultimatum Game paradigm, people refuse offers considered as unfair even though they are disadvantaged financially by doing so.

Polysubstance dependent patients display a more utilitarian profile in moral decision-making than alcohol-dependent patients, depressive patients and controls.

Background: Addiction has been shown to be associated with the endorsement of utilitarian moral judgments. Ventro-medial prefrontal cortex (VMPFC) dysfunction may explain these findings.

Methods: 100 subjects were recruited: 25 polysubstance dependent patients, 25 alcohol dependent patients, 25 patients with major depressive disorders, and 25 normal controls.

Aberrant paralimbic gray matter in incarcerated male adolescents with psychopathic traits.

Objective: To investigate the relationship between brain structure and psychopathic traits in maximum-security incarcerated male adolescents, and to examine whether the associations between brain volumes in paralimbic and limbic regions and psychopathic traits observed in incarcerated adult men extend to an independent sample of incarcerated male adolescents.

Method: A structural magnetic resonance imaging (MRI) study of regional gray matter volumes by using voxel-based morphometry in maximum-security incarcerated male adolescents (N = 218) assessed for psychopathic traits using the Hare Psychopathy Checklist-Youth Version (PCL-YV). All analyses controlled for effects of age, substance use, and brain size.

Impaired processing of emotion in music, faces and voices supports a generalized emotional decoding deficit in alcoholism.

Aim: To test the generalized emotional decoding impairment hypothesis in alcoholism.

Design: Cross-sectional behavioural study comparing emotion recognition conveyed by faces, voices and musical excerpts.

Setting: Alcohol detoxification unit of Brugmann University Hospital.

Emotional intelligence in incarcerated men with psychopathic traits.

The expression, recognition, and communication of emotional states are ubiquitous features of the human social world. Emotional intelligence (EI) is defined as the ability to perceive, manage, and reason about emotions, in oneself and others. Individuals with psychopathy have numerous difficulties in social interaction and show impairment on some emotional tasks.

Aberrant paralimbic gray matter in criminal psychopathy.

Psychopaths impose large costs on society, as they are frequently habitual, violent criminals. The pervasive nature of emotional and behavioral symptoms in psychopathy suggests that several associated brain regions may contribute to the disorder. Studies employing a variety of methods have converged on a set of brain regions in paralimbic cortex and limbic areas that appear to be dysfunctional in psychopathy.
