Book Description
This book is concerned with the extent to which childhood stress and trauma lead in relative maturity to major depression (MDD) and post-traumatic stress disorder (PTSD). The loss of synapses in the cortex, accompanying childhood maltreatment, is identified as a principal mechanism for developing these disorders. Considerable attention is given to identifying interventions that will restore lost synapses, so ameliorating these mental illnesses. The book describes the emergence of abnormal psychology in youth and adult life following childhood maltreatment. Of considerable immediate concern is the extent to which such maltreatment significantly enhances the tendency to suicide and suicidality. Next, consideration is given as to how personality disorders, such as obsessive-compulsive disorder, the very dangerous borderline personality disorder, and the publicly offensive narcissistic personality disorder, arise from childhood maltreatment. The classification or nosology of mental and personality disorders as well as the principal psychoanalytic approaches available for their treatment are sketched together with recent attempts to use novel constructs that bridge between symptoms (based on patients' behavior and self-descriptions). Recently, new techniques have been developed for brain imaging and non-invasive and localized brain stimulation. These show that nodes of the distributed brain network whose malfunction is closely related to major depressive disorders are likely to differ in their importance from patient to patient. Wonderfully, so-called 'closed-loop' stimulation techniques are now available for automatically adjusting the activity of individual nodes in individual patients, relieving them of their major depression. The results of our research, and that of others using magnetic resonance imaging of mature patients that have been maltreated as children, have been to identify the nodes that have lost gray matter. We have shown that this is likely due to the loss of synapses in these nodes. Finally, the central question of how synapses may be restored in these nodes to ameliorate major depressive disorders, post-traumatic stress disorder, and suicidality is considered, emphasizing the recent revolutionary discovery that the psychedelic ketamine restores synapses and has a therapeutic effect on mental health.

Book Description
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.

Book Description
Building on pioneering animal studies, and making use of new, noninvasive techniques for studying the human brain, research on the human amygdala has blossomed in recent years. This comprehensive volume brings together leading authorities to synthesize current knowledge on the amygdala and its role in psychological function and dysfunction. Initial chapters discuss how animal models have paved the way for work with human subjects. Next, the book examines the amygdala's involvement in emotional processing, learning, memory, and social interaction. The final section presents key advances in understanding specific clinical disorders: anxiety disorders, depression, schizophrenia, autism, and Alzheimer's disease. Illustrations include more than 25 color plates.

Book Description
This book presents the latest state of knowledge on grey matter changes in the brain following stress and trauma. Where do these changes take place and what are the underlying molecular mechanisms? These questions are addressed in several sections, providing detailed insights into the cellular and molecular alterations that occur in the brain after stress and trauma. The changes to the grey matter in certain areas of the brain are similar in stressed humans and animals, with the most likely basis for these changes being the degeneration of synaptic connections. In the book’s first sections the reader will learn about the core network of synaptic connections that are affected by stress and trauma disorders. These synaptic connections are modulated by dopamine, serotonin and Brain Derived Neurotrophic Factor (BDNF). In subsequent chapters, the NMDA-receptor mediated plasticity of these synapses is discussed, with particular attention given to how glucocorticoids can interfere with the function of BDNF and thereby affect the synapse’s physical stability. Furthermore, the reader will learn about the importance of the genetics of the glucocorticoid gene and the epigenetic control of BDNF in connection with synaptic plasticity. The authors conclude by integrating the observations summarized in the previous sections so as to present plausible hypotheses regarding the identity of the networks, synapses and molecular pathways that support fear and extinction. Providing an up-to-date overview of the mechanisms of synaptic plasticity and physiological changes in the stressed and traumatized brain, this book will appeal to researchers, clinicians and students in the neurosciences.

Book Description
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.

Book Description
The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.
