Viruses Immunity And Mental Disorders

In spite of progress in biomedical research, we know little about the causes, prevention, and treatment of the numerous mental and neurological disorders that afflict up to 15% of all individuals. In the last decade, great advances have been made in the physiopathology of mental and neurological disorders, leading to at least a partial control of Parkinson's disease, epilepsy, certain psychoses, and anxiety syndromes. Despite the fact that an underlying specific neurotransmitter deficiency has been demonstrated in Alzheimer's and Parkinson's diseases, the immune dysfunction and viral hypotheses continue to be attractive for investigators dealing with these degenerative diseases of the aging brain, which afflict 10% of senior citizens. A retrospective epidemiologic study suggests that the encephalitis lethargica and parkinsonism were almost certainly caused by the 1918 influenza virus pandemics. It must be stressed that the etiopathogenesis of many mental disorders is not known, and this ignorance has led to several untenable neurophysiological and biochemical hypotheses. Epidemiologic investigations show a high prevalence of functional psychoses and organic mental disorders. Although many of them are conceptualized as biopsychosocial disorders, recent data indicate that the biological component appears more and more as a major etiologic factor. Among the various biological hypotheses, the viral and im munologic concept has become a significant one. In view of recent discoveries in virology and immunity, it becomes clear that viral and immunologic hypotheses should be inves tigated more systematically concerning the mechanisms of numerous mental and neu rological disorders.

The Immune System and Mental Health fully investigates how immune-related cellular, molecular and anatomical changes impact mental functioning. The book combines human and animal studies to reveal immunological changes related to mental-health problems. In addition, users will find comprehensive information on new research related to the microbial composition of the gut, aka, the microbiome, and how it influences brain function and mental health. Common comorbidities with mental illness and their inherent immunological or inflammatory components are also covered. Written by leaders in the field, the book synthesizes basic and clinical research to provide a thorough understanding on the role of immunity in neuropsychiatry. Sociology, psychology, psychiatry, neuroscience and genetics have provided considerable explanations and solutions to some of the most intractable mental-health problems. But researchers are increasingly relying on investigations of the immune system to identify factors that can undermine and impair mental health. This book covers devastating mental-health conditions, such as depression, anxiety, schizophrenia, and autism-like spectrum disorders. In addition, degenerative disorders of the brain, such as Parkinson’s and Alzheimer’s-like dementia are explored. Considers both basic human and animal studies that address immunological changes relating to mental health problems across the lifespan Incorporates techniques, concepts and ideas from a variety of social, behavioral and life sciences Explores the relatively new area of the microbiome and how the microbial composition of the gut influences brain function and mental health

This publication presents evidence about the magnitude and severe consequences of comorbidity of mental and physical illnesses from a personal and societal perspective. Leading experts address the huge burden of co-morbidity to the affected individual as well as the public health aspects, the costs to society and interaction with factors stemming from the context of socioeconomic developments. The authors discuss the clinical challenge of managing cardiovascular illnesses, cancer, infectious diseases and other physical illness when they occur with a range of mental and behavioral disorders, including substance abuse, eating disorders and anxiety. Also covered are the organization of health services, the training of different categories of health personnel and the multidisciplinary engagement necessary to prevent and manage comorbidity effectively. The book is essential reading for general practitioners, internists, public health specialists, psychiatrists, cardiologists, oncologists, medical educationalists and other health care professionals.

This volume contains the contributions to the "3rd Expert Meeting in Psychoneuroimmunology", held in Munich, Germany in autumn 1997. Clinical psychiatrists, neuroscientists and researchers in basic immuno logy from Europe and the USA gather together annually at this new tra ditional meeting to discuss new findings and trends in the relationship between psychiatric disorders and the immune system. Pinpointed at the Munich meeting in particular were the possible influence of viral infec tions on psychiatric disorders, especially schizophrenia, and the possible pathophysiological mechanisms affecting psychiatric disorders. These mechanisms include viral-induced alteration, cytokine production, and the role of the HLA system. One chapter is devoted to the influence of viral infections during pregnancy; another to the first results of experimental therapy especial ly regarding the immune system. The immunological aspects not only of schizophrenia but also of depression, anxiety disorders, sleep and headache were also discussed at the meeting, and two further chapters cover methodological aspects related to clinical and experimental pitfalls in psychoneuroimmunology. The psychoneuroimmunology of psychiatric disorders is a rapidly expanding field, and research is increasing on the therapeutic aspects. This is reflected by one of the main themes of the "4th Expert Meeting in Psychoneuroimmunology", jointly held in autumn 1998 in Bethesda, Maryland, USA, with the Stanley Foundation Meeting in Neurovirology, devoted to therapeutic strategies deriving from psychoneuroimmunolo gical findings. The "5th Expert Meeting in Psychoneuroimmunology" will be held in 1999 in Innsbruck, Austria.

This book explains how stress – either psychological or physical – can activate and/or paralyse human innate or adaptive immunity. Adequate immunity is crucial for maintaining health, both on Earth and in space. During space flight, human physiology is specifically challenged by complex environmental stressors, which are most pronounced during lunar or interplanetary missions. Adopting an interdisciplinary approach, the book identifies the impact of these stressors – the space exposome – on immunity as a result of (dys-)functions of specific cells, organs and organ networks. These conditions (e.g. gravitation changes, radiation, isolation/confinement) affect immunity, but at the same time provide insights that may help to prevent, diagnose and address immune-related health alterations. Written by experts from academia, space agencies and industry, the book is a valuable resource for professionals, researchers and students in the field of medicine, biology and technology. The chapters “The Impact of Everyday Stressors on the Immune System and Health”, “Stress and Radiation Responsiveness” and “Assessment of Radiosensitivity and Biomonitoring of Exposure to Space adiation” are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

Persistent Viral Infections Edited by Rafi Ahmed Emory Vaccine Center, Atlanta, USA and Irvin S. Y. Chen UCLA School of Medicine, Los Angeles, USA During the past decade much of our attention has focused on diseases associated with viral persistence. Major breakthroughs in immunology, and the advent of molecular approaches to study pathogenesis have increased our understanding of the complex virus-host interactions that occur during viral persistence. Persistent Viral Infections focuses on: * The pathogenesis and immunology of chronic infections * Animal models that provide, or have the potential to provide, major insights This volume will be essential reading for virologists, immunologists, oncologists and neurologists.

With recent studies using genetic, epigenetic, and other molecular and neurochemical approaches, a new era has begun in understanding pathophysiology of suicide. Emerging evidence suggests that neurobiological factors are not only critical in providing potential risk factors but also provide a promising approach to develop more effective treatment and prevention strategies. The Neurobiological Basis of Suicide discusses the most recent findings in suicide neurobiology. Psychological, psychosocial, and cultural factors are important in determining the risk factors for suicide; however, they offer weak prediction and can be of little clinical use. Interestingly, cognitive characteristics are different among depressed suicidal and depressed nonsuicidal subjects, and could be involved in the development of suicidal behavior. The characterization of the neurobiological basis of suicide is in delineating the risk factors associated with suicide. The Neurobiological Basis of Suicide focuses on how and why these neurobiological factors are crucial in the pathogenic mechanisms of suicidal behavior and how these findings can be transformed into potential therapeutic applications.

There has been a tremendous increase in interest in the neuropathogenicity of viruses during the past decade as we have come to recognize that the human immunodeficiency virus, which causes the acquired immunodeficiency syndrome (AIDS), can infect glial cells and cause neurological disease. Yet this increase has not been limited to AIDS but has extended to viruses that infect either or both the central and peripheral nervous systems. The changes examined here include both neurological and psychological diseases or syndromes. Moreover, the chapters in this volume review the interaction of the host immune system with the viruses examined and how such interactions may increase or decrease the neuropatho genicity of the viruses. Questions regarding viral neuropathogenesis include: (I) What is the mode of transmission of virus to the nervous system? (2) What types of cells are infected, and do they contain receptors for the virus? (3) What is the extent of damage that results from viral infection? (4) What are the immunologic mecha nisms by which damage is mediated or limited? Many of these questions remain unanswered, but this volume delves into efforts to provide some answers.
