abstract = {Accumulating research demonstrates that repetitive sub-concussive impacts can alter the structure, function and connectivity of the brain. However, the functional significance of these alterations as well as the independent contribution of concussive and sub-concussive impacts to neurophysiological and neuropsychological health are unclear. Accordingly, we compared the neurophysiological and neuropsychological function of contact athletes with (concussion group) and without (sub-concussion group) a history of concussion, to non-contact athletes. We evaluated event-related brain potentials (ERPs) elicited during an oddball task and performance on a targeted battery of neuropsychological tasks. Athletes in the sub-concussion and concussion groups exhibited similar amplitude reductions in the ERP indices of attentional resource allocation (P3b) and attentional orienting (P3a) relative to non-contact athletes. However, only athletes in the concussion group exhibited reduced amplitude in the ERP index of perceptual attention (N1). Athletes in the sub-concussion and concussion groups also exhibited deficits in memory recall relative to non-contact athletes, but athletes in the concussion group also exhibited significantly more recall errors than athletes in the sub-concussion group. Additionally, only athletes in the concussion group exhibited response delays during the oddball task. The current findings suggest that sub-concussive impacts are associated with alterations in the neurophysiological and neuropsychological indices of essential cognitive functions, albeit to a lesser degree than the combination of sub-concussive and concussive impacts. © 2016 Elsevier B.V.},

Computerized testing batteries are often employed as baseline and postinjury measures of cognitive function, with the Immediate Postconcussion Assessment and Cognitive Testing (ImPACT) being the most used of all the current testing platforms. The current study compared 10- to 12-year-old children across the composite scores yielded by the ImPACT and provided normative data on each of the subtests used to calculate the composite scores. Normative data are separated by gender for athletes aged 10 to 12 years old, as this is the current age bracket used by the ImPACT.

(The following abstract of the original article appeared in record [rid]2016-18089-008[/rid]). This exploratory study was designed to examine the neuropsychological effects of sports-related head trauma\textemdashspecifically, repetitive subconcussive impacts or head blows that do not result in a diagnosable concussion. The researchers compared the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) neurocognitive test scores of 2 groups of nonconcussed youth athletes (n = 282), grouped according to the frequency of concussions in their respective sports, with the assumption that more subconcussive impacts occur in sports in which there are more reported concussions. The results indicated that high-contact-sport (football) athletes had significantly poorer performance in processing speed and reaction time compared with athletes in low-contact sports (wrestling, soccer, baseball, judo, and basketball). This study into the effects of repetitive subconcussive head trauma tentatively raises concern that participation in high-contact sports, even without evidence of a diagnosable concussion, could result in lowered neuropsychological functioning among high school athletes. Limitations of this exploratory research effort are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

The purpose of the current study was to validate the utility of the SAC as an embedded screening measure for insufficient effort in independent medical examinations (IME) and personal injury cases. Method: A known-groups design was used to examine the SACs utility for the detection of insufficient effort in 75 de-identified private IME and civil litigation evaluations. Initial classifications of insufficient effort were made independently of SAC scores, on the basis of having two or more scores falling below established cut-offs on previously validated neuropsychological measures. Results: Results suggest that the total score on the SAC significantly distinguishes effortful respondents from those exhibiting insufficient effort. Empirically derived cut-off scores yielded adequate sensitivity (.62-.95) and negative predictive power (.93-.97). Conclusions: While optimal cut-off scores depend upon intended use, our data suggest that the SAC is useful as a potential screener for insufficient effort, after which one can employ additional measures to rule out false-positives. Further research is required before cut-off scores can be recommended for clinical use. © 2015 Taylor and Francis.},

abstract = {There has been unprecedented interest in sport-related concussions from many and varied sources including media, sports leagues, players’ unions, lawyers, legislators, scientists, clinicians, parents, coaches, and the athletes themselves. This interest has been fueled by epidemiologic data which indicate that concussions frequently occur at all ages, at all levels of play, and across a broad range of sports. The ubiquitous nature of the injury has also been coupled with concerns about whether and what type of relationships may exist between sports-related brain injury and the development of later neurodegenerative disease processes. The development of Sports Neuropsychology has largely paralleled the interest in sports concussions, making it a young and rapidly growing area of clinical and research interest. The youth of sports neuropsychology coupled with a focus on a poorly defined injury while being subject to unprecedented media, public, legislative, and legal scrutiny presents unique and important challenges to the ethical practice of sports neuropsychology. This paper explores these challenges by reviewing the brief history of sports neuropsychology, providing a basic review of the APA Code of Ethics, and discussing key ethical constructs such as beneficence, non-maleficence, and autonomy. The role of ethnic/racial cultural considerations in sports neuropsychology is discussed as well as ethical questions related to test use and development, the various roles that sports neuropsychologists play in sports medicine, and several illustrations of the challenges faced by sports neuropsychologists related to confidentiality, competence, role definition, and role boundaries.

abstract = {Background: Chronic traumatic encephalopathy (CTE) is a recently revived term used to describe a neurodegenerative process that occurs as a long term complication of repetitive mild traumatic brain injury (TBI). Corsellis provided one of the classic descriptions of CTE in boxers under the name "dementia pugilistica" (DP). Much recent attention has been drawn to the apparent association of CTE with contact sports (football, soccer, hockey) and with frequent battlefield exposure to blast waves generated by improvised explosive devices (IEDs). Recently, a promising serum biomarker has been identified by measurement of serum levels of the neuronal microtubule associated protein tau. New positron emission tomography (PET) ligands (e.g., [18F] T807) that identify brain tauopathy have been successfully deployed for the in vitro and in vivo detection of presumptive tauopathy in the brains of subjects with clinically probable CTE. Methods. Major academic and lay publications on DP/CTE were reviewed beginning with the 1928 paper describing the initial use of the term CTE by Martland. Results: The major current concepts in the neurological, psychiatric, neuropsychological, neuroimaging, and body fluid biomarker science of DP/CTE have been summarized. Newer achievements, such as serum tau and [18F] T807 tauopathy imaging, are also introduced and their significance has been explained. Conclusion: Recent advances in the science of DP/CTE hold promise for elucidating a long sought accurate determination of the true prevalence of CTE. This information holds potentially important public health implications for estimating the risk of contact sports in inflicting permanent and/or progressive brain damage on children, adolescents, and adults. © 2014Gandy et al.; licensee BioMed Central Ltd.},

New positron emission tomography (PET) ligands (e.g., [18F] T807) that identify brain tauopathy have been successfully deployed for the in vitro and in vivo detection of presumptive tauopathy in the brains of subjects with clinically probable CTE. Methods. Major academic and lay publications on DP/CTE were reviewed beginning with the 1928 paper describing the initial use of the term CTE by Martland. Results: The major current concepts in the neurological, psychiatric, neuropsychological, neuroimaging, and body fluid biomarker science of DP/CTE have been summarized. Newer achievements, such as serum tau and [18F] T807 tauopathy imaging, are also introduced and their significance has been explained. Conclusion: Recent advances in the science of DP/CTE hold promise for elucidating a long sought accurate determination of the true prevalence of CTE. This information holds potentially important public health implications for estimating the risk of contact sports in inflicting permanent and/or progressive brain damage on children, adolescents, and adults. © 2014Gandy et al.; licensee BioMed Central Ltd.},

abstract = {Accumulating research demonstrates that repetitive sub-concussive impacts can alter the structure, function and connectivity of the brain. However, the functional significance of these alterations as well as the independent contribution of concussive and sub-concussive impacts to neurophysiological and neuropsychological health are unclear. Accordingly, we compared the neurophysiological and neuropsychological function of contact athletes with (concussion group) and without (sub-concussion group) a history of concussion, to non-contact athletes. We evaluated event-related brain potentials (ERPs) elicited during an oddball task and performance on a targeted battery of neuropsychological tasks. Athletes in the sub-concussion and concussion groups exhibited similar amplitude reductions in the ERP indices of attentional resource allocation (P3b) and attentional orienting (P3a) relative to non-contact athletes. However, only athletes in the concussion group exhibited reduced amplitude in the ERP index of perceptual attention (N1). Athletes in the sub-concussion and concussion groups also exhibited deficits in memory recall relative to non-contact athletes, but athletes in the concussion group also exhibited significantly more recall errors than athletes in the sub-concussion group. Additionally, only athletes in the concussion group exhibited response delays during the oddball task. The current findings suggest that sub-concussive impacts are associated with alterations in the neurophysiological and neuropsychological indices of essential cognitive functions, albeit to a lesser degree than the combination of sub-concussive and concussive impacts. © 2016 Elsevier B.V.},

Computerized testing batteries are often employed as baseline and postinjury measures of cognitive function, with the Immediate Postconcussion Assessment and Cognitive Testing (ImPACT) being the most used of all the current testing platforms. The current study compared 10- to 12-year-old children across the composite scores yielded by the ImPACT and provided normative data on each of the subtests used to calculate the composite scores. Normative data are separated by gender for athletes aged 10 to 12 years old, as this is the current age bracket used by the ImPACT. These norms may be helpful in the interpretation of the ImPACT clinical report and further delineation of areas of neurocognitive dysfunction. © 2016, Copyright © Taylor \& Francis Group, LLC.},

(The following abstract of the original article appeared in record [rid]2016-18089-008[/rid]). This exploratory study was designed to examine the neuropsychological effects of sports-related head trauma\textemdashspecifically, repetitive subconcussive impacts or head blows that do not result in a diagnosable concussion. The researchers compared the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) neurocognitive test scores of 2 groups of nonconcussed youth athletes (n = 282), grouped according to the frequency of concussions in their respective sports, with the assumption that more subconcussive impacts occur in sports in which there are more reported concussions. The results indicated that high-contact-sport (football) athletes had significantly poorer performance in processing speed and reaction time compared with athletes in low-contact sports (wrestling, soccer, baseball, judo, and basketball). This study into the effects of repetitive subconcussive head trauma tentatively raises concern that participation in high-contact sports, even without evidence of a diagnosable concussion, could result in lowered neuropsychological functioning among high school athletes. Limitations of this exploratory research effort are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

The purpose of the current study was to validate the utility of the SAC as an embedded screening measure for insufficient effort in independent medical examinations (IME) and personal injury cases. Method: A known-groups design was used to examine the SACs utility for the detection of insufficient effort in 75 de-identified private IME and civil litigation evaluations. Initial classifications of insufficient effort were made independently of SAC scores, on the basis of having two or more scores falling below established cut-offs on previously validated neuropsychological measures. Results: Results suggest that the total score on the SAC significantly distinguishes effortful respondents from those exhibiting insufficient effort. Empirically derived cut-off scores yielded adequate sensitivity (.62-.95) and negative predictive power (.93-.97). Conclusions: While optimal cut-off scores depend upon intended use, our data suggest that the SAC is useful as a potential screener for insufficient effort, after which one can employ additional measures to rule out false-positives. Further research is required before cut-off scores can be recommended for clinical use. © 2015 Taylor and Francis.},

abstract = {There has been unprecedented interest in sport-related concussions from many and varied sources including media, sports leagues, players’ unions, lawyers, legislators, scientists, clinicians, parents, coaches, and the athletes themselves. This interest has been fueled by epidemiologic data which indicate that concussions frequently occur at all ages, at all levels of play, and across a broad range of sports. The ubiquitous nature of the injury has also been coupled with concerns about whether and what type of relationships may exist between sports-related brain injury and the development of later neurodegenerative disease processes. The development of Sports Neuropsychology has largely paralleled the interest in sports concussions, making it a young and rapidly growing area of clinical and research interest. The youth of sports neuropsychology coupled with a focus on a poorly defined injury while being subject to unprecedented media, public, legislative, and legal scrutiny presents unique and important challenges to the ethical practice of sports neuropsychology. This paper explores these challenges by reviewing the brief history of sports neuropsychology, providing a basic review of the APA Code of Ethics, and discussing key ethical constructs such as beneficence, non-maleficence, and autonomy. The role of ethnic/racial cultural considerations in sports neuropsychology is discussed as well as ethical questions related to test use and development, the various roles that sports neuropsychologists play in sports medicine, and several illustrations of the challenges faced by sports neuropsychologists related to confidentiality, competence, role definition, and role boundaries. Although this article does not provide simple answers to complex questions, it does highlight areas in need of thoughtful discourse for clinicians engaged in the dynamic and evolving nature of ethical sports neuropsychology practice. © 2015, Springer Science+Business Media New York.},
