Download or read book The Cerebral Circulation written by Marilyn J. Cipolla and published by Biota Publishing. This book was released on 2016-07-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.

Download or read book Brain Protection written by Klaus Wiedemann and published by Springer. This book was released on 1983 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant progress has doubtlessly been made in the field of cere bral protection compared to earlier centuries, as recently reviewed by Elisabeth Frost (6). She cites the recommendations for treat ment of brain trauma by Areteus, a Greek physician of the second century A. D. He expressed quite modem views with regard to the need for prompt action considering complications that follow even minor symptoms. He advised burr holes for evacuation of hema toma in seizures, the use of diuretics and, most interestingly, also hypothermia. German surgeons of the 17th century had little more to offer than prescriptions of which the most effective constituent was alcohol (10). Thus, Sir Astley Cooper was probably the next surgeon to make noteworthy contributions when advising the use of leeches to the temporal artery and other means of bleeding in stead of surgical intervention in cases of raised intracranial pressure (loc. cit. 6). Although our knowledge has greatly expanded during the last two decades, extensive discussions have led to only few conclusions. Promising results from animal studies were translated to clinical sit uations only to yield controversial and sometimes confusing results. Since the observations of Brierly (5) on ischemic cell damage, im proved information on structural aspects, probably even related to concomitant biochemical studies, should allow the validity of thera peutic concepts to be verified. Investigations on cerebral ischemia have led to the differentiation of synaptic transmission failure and membrane failure.

Download or read book Sports Related Concussions in Youth written by National Research Council and published by National Academies Press. This book was released on 2014-02-04 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.

Download or read book Rewired written by Carl D. Marci MD and published by Harvard University Press. This book was released on 2022-05-17 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Living in an age of digital distraction has wreaked havoc on our brains—but there’s much we can do to restore our tech–life balance. We live in a world that is always on, where everyone is always connected. But we feel increasingly disconnected. Why? The answer lies in our brains. Carl D. Marci, MD, a leading expert on social and consumer neuroscience, reviews the mounting evidence that overuse of smart phones and social media is rewiring our brains, resulting in a losing deal: we are neglecting the relationships that sustain us and keep us healthy in favor of weaker and more ephemeral ties. The ability to connect and form strong social bonds is fundamental to human experience and emerged through unique structures in our brains. But ever-more-powerful technologies and ubiquitous access to media have hijacked our need to connect intimately and emotionally with others. The quick highs of clicking “like” and swiping right overstimulate the same neurological reward centers associated with social relationships. The habits that accompany our digital lifestyles are putting tremendous pressure on critical components of the brain associated with attention, emotion, and memory, changing how we process information and altering how we communicate and relate, even at a physiological level. As a psychiatrist working at the forefront of research on the impact of digital technology, Marci has seen this transformation up close and developed a range of responses. Rewired provides scientifically supported solutions for everyone who wants to restore their tech–life balance—from parents concerned about their children’s exposure to the internet to stressed workers dealing with the deluge of emails and managing the expectation of 24/7 availability.

Download or read book The Teenage Brain written by Frances E. Jensen and published by Harper Collins. This book was released on 2015-01-06 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: A New York Times Bestseller Renowned neurologist Dr. Frances E. Jensen offers a revolutionary look at the brains of teenagers, dispelling myths and offering practical advice for teens, parents and teachers. Dr. Frances E. Jensen is chair of the department of neurology in the Perelman School of Medicine at the University of Pennsylvania. As a mother, teacher, researcher, clinician, and frequent lecturer to parents and teens, she is in a unique position to explain to readers the workings of the teen brain. In The Teenage Brain, Dr. Jensen brings to readers the astonishing findings that previously remained buried in academic journals. The root myth scientists believed for years was that the adolescent brain was essentially an adult one, only with fewer miles on it. Over the last decade, however, the scientific community has learned that the teen years encompass vitally important stages of brain development. Samples of some of the most recent findings include: Teens are better learners than adults because their brain cells more readily "build" memories. But this heightened adaptability can be hijacked by addiction, and the adolescent brain can become addicted more strongly and for a longer duration than the adult brain. Studies show that girls' brains are a full two years more mature than boys' brains in the mid-teens, possibly explaining differences seen in the classroom and in social behavior. Adolescents may not be as resilient to the effects of drugs as we thought. Recent experimental and human studies show that the occasional use of marijuana, for instance, can cause lingering memory problems even days after smoking, and that long-term use of pot impacts later adulthood IQ. Multi-tasking causes divided attention and has been shown to reduce learning ability in the teenage brain. Multi-tasking also has some addictive qualities, which may result in habitual short attention in teenagers. Emotionally stressful situations may impact the adolescent more than it would affect the adult: stress can have permanent effects on mental health and can to lead to higher risk of developing neuropsychiatric disorders such as depression. Dr. Jensen gathers what we’ve discovered about adolescent brain function, wiring, and capacity and explains the science in the contexts of everyday learning and multitasking, stress and memory, sleep, addiction, and decision-making. In this groundbreaking yet accessible book, these findings also yield practical suggestions that will help adults and teenagers negotiate the mysterious world of adolescent development.
Download or read book Brain Protection in Schizophrenia Mood and Cognitive Disorders written by Michael S. Ritsner and published by Springer Science & Business Media. This book was released on 2010-06-16 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuroprotection is a novel perspective for the treatment of disorders that lead to neurodegeneration and disabilities as a result of deterioration of neurons due to apoptosis, oxidative stress, excitotoxicity, and other mechanisms. These mechanisms have implications not only for neurodegenerative disorders, but also for schizophrenia, mood and cognitive disorders. The purpose of this book is to provide an up-to-date overview of basic and clinical studies concerning the neuroprotective approach, mechanisms, and several compounds with neuroprotective properties that may contribute to more efficacious treatment of major mental health disorders. The book is divided into two sections. The first section serves as an introduction and overview of conceptual issues of the neuroprotective approach, and some neurobiological advances. Chapters in this section review definitions, perspectives, and issues that provide a conceptual base for the rest of the book. In addition, this part includes chapters in which the authors present and discuss the findings from basic studies of neurodegenerative mechanisms that are associated with the pathogenesis of major mental health disorders. The second section focuses on findings obtained from clinical trials with neuroprotective compounds, and neuromodulatory techniques. The take-home message is that principles of the neuroprotective approach may be applied to treatment of schizophrenia, mood and cognitive disorders. Contributors to this book are among the most active investigators and clinicians in the field who provide new perspectives not only clarifying ongoing controversies but also propose diverse aspects and new insights to neuroprotection. This book is intended for a broad readership, which includes a broad spectrum of readers including neuroscientists, psychiatrists, neurologists, pharmacologists, clinical psychologists, general practitioners, geriatricians, graduate students, and policy makers in the fields of mental health.
