Mild traumatic brain injury (MTBI) is one of the most common injuries seen among athletes. More commonly known as concussions, these injuries are often overlooked and treated poorly due to misconceptions athletes and parents have. Because MTBI is difficult to diagnose in athletes, it is important to study why and how they occur. It is hypothesized that major significant neurophysiological abnormalities will be seen in both functional magnetic resonance imaging (fMRI) and electroencephalogram (EEG) after MTBI. This study consisted of forty-four collegiate rugby players participating in the EEG studies, where sixteen subjects were uninjured and used as a baseline control and where twenty-eight subjects were injured and received a MTBI. The study also consisted of thirty collegiate athletes participating in the fMRI study, fifteen subjects being uninjured and considered to be the control, while fifteen subjects were injured after suffering from a MTBI. According to the EEG results, no significant differences were found for TBI discriminant, TBI Severity, and TBI probability scores between baseline and MTBI subjects. However, when looking at the data, a general trend is seen of a lesser TBI discriminant score for baseline, and greater TBI Severity Index and TBI probability index for the MTBI subjects. According to the low resolution brain electromagnetic tomography (LORETA) analysis conducted, the most common areas affected by the brain injury in concussed patients are the parahippocampal gyrus in the limbic lobe and the middle temporal gyrus in the temporal lobe. According to the fMRI results, in all comparisons between conditions, the subjects suffering from a MTBI had significantly higher levels of activation in the brain when performing tasks compared to the control subjects. According to the results of this study, as well as others completed in the past, it is important to use a comprehensive approach in dealing with a MTBI obtained by an athlete in sport, which includes neuropsychological tests, EEG, and fMRI.

In the past decade, few subjects at the intersection of medicine and sports have generated as much public interest as sports-related concussions - especially among youth. Despite growing awareness of sports-related concussions and campaigns to educate athletes, coaches, physicians, and parents of young athletes about concussion recognition and management, confusion and controversy persist in many areas. Currently, diagnosis is based primarily on the symptoms reported by the individual rather than on objective diagnostic markers, and there is little empirical evidence for the optimal degree and duration of physical rest needed to promote recovery or the best timing and approach for returning to full physical activity. Sports-Related Concussions in Youth: Improving the Science, Changing the Culture reviews the science of sports-related concussions in youth from elementary school through young adulthood, as well as in military personnel and their dependents. This report recommends actions that can be taken by a range of audiences - including research funding agencies, legislatures, state and school superintendents and athletic directors, military organizations, and equipment manufacturers, as well as youth who participate in sports and their parents - to improve what is known about concussions and to reduce their occurrence. Sports-Related Concussions in Youth finds that while some studies provide useful information, much remains unknown about the extent of concussions in youth; how to diagnose, manage, and prevent concussions; and the short- and long-term consequences of concussions as well as repetitive head impacts that do not result in concussion symptoms. The culture of sports negatively influences athletes' self-reporting of concussion symptoms and their adherence to return-to-play guidance. Athletes, their teammates, and, in some cases, coaches and parents may not fully appreciate the health threats posed by concussions. Similarly, military recruits are immersed in a culture that includes devotion to duty and service before self, and the critical nature of concussions may often go unheeded. According to Sports-Related Concussions in Youth, if the youth sports community can adopt the belief that concussions are serious injuries and emphasize care for players with concussions until they are fully recovered, then the culture in which these athletes perform and compete will become much safer. Improving understanding of the extent, causes, effects, and prevention of sports-related concussions is vitally important for the health and well-being of youth athletes. The findings and recommendations in this report set a direction for research to reach this goal.

In summarizing current insights and controversies over concussions in athletics, this book makes the vital point that symptom resolution does not necessarily mean injury resolution. Research shows that dysfunctional pathways continue for extended periods even after a minor concussion. Until the consequences of short-term perturbations and long-term residual brain dysfunctions are better understood, concussions must be treated with respect and given a higher priority for continued research activity.

Now in a fully revised and expanded second edition, this comprehensive text remains a timely and major contribution to the literature that addresses the neuromechanisms, predispositions, and latest developments in the evaluation and management of concussive injuries. Concussion, also known as mild traumatic brain injury, continues to be a significant public health concern with increased attention focusing on treatment and management of this puzzling epidemic as well as controversies within the field. The book is comprised of five thematic sections: current developments in evaluation; biomechanical mechanisms; neural substrates, biomarkers, genetics and brain imaging; pediatric considerations; and clinical management and rehabilitation. Since the publication of the original edition in 2014, much has changed regarding the current understanding of mild traumatic brain injury including development of more precise imaging modalities, development and classification of new biomarkers, and updates to clinical treatment and management of athletic concussion. This new edition will include new chapters targeting the influence of genetics on concussive injury, as well as an expansion on the knowledge of pediatric response to concussion and the influence of repetitive subconcussive impacts on athlete health. An invaluable contribution to the literature, Concussions in Athletics: From Brain to Behavior reestablishes itself as a state-of-the-art reference that will be of significant interest to a wide range of clinicians, researchers, administrators, and policy makers, and this updated version aims to narrow the gap between research findings and clinical management of sports-related concussion and other mild traumatic brain injury. The second edition also attempts to broaden the scope of the knowledge to apply to more professionals and pre-professionals in the fields of neuroscience, neuropsychology, and other allied health professionals that closely work with athletes and sports medicine professionals.

Traumatic brain injury (TBI) in sports has become an important international public health issue over the past two decades. However, until recently, return to play decisions following a sports-related traumatic brain injury have been based on anecdotal evidence and have not been based on scientifically validated clinical protocols. Over the past decade, the field of Neuropsychology has become an increasingly important component of the return to play decision making process following TBI. Neuropsychological assessment instruments are increasingly being adapted for use with athletes throughout the world and the field of sports neuropsychology appears to be a rapidly evolving subspecialty. This book provides a comprehensive overview of the application of neuropsychological assessment instruments in sports, and it is structured to present a global perspective on contemporary research. In addition to a review of current research, Traumatic Brain Injury in Sports: An International Neuropsychological Perspective, presents a thorough review of current clinical models that are being implemented internationally within American and Australian rules football, soccer, boxing, ice hockey, rugby and equestrian sports.

This is the first neuropsychology book to translate exciting findings from the recent explosion of research on sport-related concussion to the broader context of mild traumatic brain injury (MTBI) and post-concussive syndrome (PCS) in the general population. In addition, it includes a Continuing Education (CE) component administered by the American Academy of Clinical Neuropsychology. Traumatic brain injuries constitute a major global public health problem, but until now, MTBIs, which constitute up to 90 percent of all treated TBIs, have been difficult to evaluate and manage clinically because of the absence of a viable model. Dr. McCrea's book thus provides a welcome evidence base for all clinicians - including psychologists, neuropsychologists, neurologists, neurosurgeons, rehabilitation medicine physicians, physiatrists, and nurses - involved in the clinical diagnosis and treatment of MTBI, as well as attorneys involved in personal injury litigation and personal injury defense. Each section of the book ends with a helpful summary of the 'Top 10 Conclusions.' Instructions for earning AACN-administered CE credit are included.

From translating the patient’s medical records and test results to providing recommendations, the neuropsychological evaluation incorporates the science and practice of neuropsychology, neurology, and psychological sciences. The Little Black Book of Neuropsychology brings the practice and study of neuropsychology into concise step-by-step focus—without skimping on scientific quality. This one-of-a-kind assessment reference complements standard textbooks by outlining signs, symptoms, and complaints according to neuropsychological domain (such as memory, language, or executive function), with descriptions of possible deficits involved, inpatient and outpatient assessment methods, and possible etiologies. Additional chapters offer a more traditional approach to evaluation, discussing specific neurological disorders and diseases in terms of their clinical features, neuroanatomical correlates, and assessment and treatment considerations. Chapters in psychometrics provide for initial understanding of brain-behavior interpretation as well as more advanced principals for neuropsychology practice including new diagnostic concepts and analysis of change in performance over time. For the trainee, beginning clinician or seasoned expert, this user-friendly presentation incorporating ‘quick reference guides’ throughout which will add to the practice armentarium of beginning and seasoned clinicians alike. Key features of The Black Book of Neuropsychology: Concise framework for understanding the neuropsychological referral. Symptoms/syndromes presented in a handy outline format, with dozens of charts and tables. Review of basic neurobehavioral examination procedure. Attention to professional issues, including advances in psychometrics and diagnoses, including tables for reliable change for many commonly used tests. Special “Writing Reports like You Mean It” section and guidelines for answering referral questions. Includes appendices of practical information, including neuropsychological formulary. The Little Black Book of Neuropsychology is an indispensable resource for the range of practitioners and scientists interested in brain-behavior relationships. Particular emphasis is provided for trainees in neuropsychology and neuropsychologists. However, the easy to use format and concise presentation is likely to be of particular value to interns, residents, and fellows studying neurology, neurological surgery, psychiatry, and nurses. Finally, teachers of neuropsychological and neurological assessment may also find this book useful as a classroom text. "There is no other book in the field that covers the scope of material that is inside this comprehensive text. The work might be best summed up as being a clinical neuropsychology postdoctoral residency in a book, with the most up to date information available, so that it is also an indispensible book for practicing neuropsychologists in addition to students and residents...There is really no book like this available today. It skillfully brings together the most important foundationsof clinical neuropsychology with the 'nuts and bolts' of every facet of assessment. It also reminds the more weathered neuropsychologists among us of the essential value of neuropsychological assessment...the impact of the disease on the patient’s cognitive functioning and behavior may only be objectively quantified through a neuropsychological assessment."
