Book Description
Most of us spend at least two-thirds of our lives either sitting or standing. It is somewhat surprising, therefore, to find not a single book devoted to disorders caused by derangements of the normal physiological adjustments to changes in posture. In fact, until very recently, medical students have not even been advised to measure the blood pressure and heart rate in the upright posture as part of the routine physical examination. Although Bradbury and Eggleston first described orthostatic hypotension as a consequence of autonomic insufficiency in 1925, interest in orthostatic disorders has been slow to develop in the subsequent years. It is well known that the change from recumbency to the standing posture stimulates neurological, endocrine, and cardiovascular adjustments that ensure maintenance of a normal circulation despite the effects of gravitational forces. The mechanisms of these physiological responses to orthostasis have been stud ied by many investigators. Some of the defects to which antigravitational com pensatory mechanisms are subject, such as postural hypotension resulting from autonomic failure, have been studied intensively and have become part of the general knowledge of most medical practitioners. Other orthostatic disorders such as various other postural abnormalities of blood pressure control, and orthostatic edema-have received far less attention and have been unable to compete with the more dramatic and life-threatening ailments of humankind for a place in our standard medical texts. These disorders often give rise to distressing symptoms and may lead to severe impairment of health.

Book Description
"The Dysautonomia Project" is a much needed tool for physicians, patients, or caregivers looking to arm themselves with the power of knowledge. It combines current publications from leaders in the field of autonomic disorders with explanations for doctors and patients about the signs and symptoms, which will aid in reducing the six-year lead time to diagnosis.

Book Description
This book provides a comprehensive and practical guide to orthostatic hypotension (OH) for doctors and nurses involved in the care of older adults, together with a state-of-the-art update on OH, covering its epidemiology, pathophysiology, assessment, diagnosis, causes, prevention, management, and relevance for geriatric practice. In addition, it addresses mechanisms of orthostatic tolerance and other orthostasis related conditions, as well as drugs, comorbidities and geriatric syndromes related to OH. The homeostatic ability to maintain blood pressure while standing requires an adequate blood volume and the integrity of the nervous system, heart, blood vessels and muscle pump. However, in older adults, some age-related factors can contribute to the development of OH. For example, decreased baroreflex sensitivity, α-1-adrenergic vasoconstrictor response to sympathetic stimuli, parasympathetic activity, renal salt and water conservation, increased vascular stiffness and decreased ventricular diastolic filling, as well as concentrated capacities of the kidney may be associated with changes in postural blood pressure. It has also been shown that OH is associated with falls, cardiac events, heart failure, stroke, reduced quality of life, and increased risk of overall mortality in these patients. “Orthostatic Hypotension in Older Adults” will be of considerable interest to all professionals working in the fields of geriatrics, geriatric psychiatry, neurology, internal medicine, cardiology, and emergency medicine, or working with older people in hospitals or in their community.

Book Description
The essential guide to living with orthostatic intolerance. Orthostatic intolerance (OI) describes a group of circulatory disorders whose symptoms are characterized by a dramatic drop in blood flow to the brain when people sit down or stand up. It is often associated with other acute issues, such as substantial drops in blood pressure, tachycardia, dizziness, and fainting, or long-term problems, such as chronic fatigue, fibromyalgia, and "long COVID." Living Well with Orthostatic Intolerance is an indispensable guide for those diagnosed with the disorder, their families, and physicians. Written by Peter C. Rowe, MD, a pediatrician, researcher, and professor who directs the Chronic Fatigue Clinic at Johns Hopkins Children's Center, this guide explains: • The symptoms, causes, and different forms of OI • What a diagnosis of OI entails • How to manage OI symptoms using medications, physical therapy, and other treatments • How diet affects OI Guided by decades of research on managing and treating OI patients, Dr. Rowe provides illustrative case studies to help explain the disease and includes additional resources for further information.

Book Description
This book describes the varying clinical manifestations of postural tachycardia syndrome (PoTS) and provides a robust yet practical set of clinical tools for those managing patients suffering with this syndrome. Guidance is provided by a range of disciplines relevant to PoTS including general and specialist assessments, associated conditions, diagnostic considerations, therapy and service models. Postural Tachycardia Syndrome: A Concise and Practical Guide to Management and Associated Conditions presents the scientific background and practical information for the busy medical professional, illustrating key features with care-based materials to help them manage this condition, which can be a challenge for patients and clinicians alike.

Book Description
DDisorders associated with dysfunction of the autonomic nervous system are quite common yet frequently unrecognized. The quantitative autonomic testing presented here can be invaluable tool for evaluation of these disorders. This manual fills a gap in the literature and deals mainly with practical aspects of autonomic testing. In accord with the "good picture is worth a thousand words" mantra, signal drawings are heavy used throughout the text to facilitate the readers' knowledge. Autonomic Testing is the optimal guide for autonomic fellows, residents in neurology, general medicine and other specialties or for everybody that is interested in performing and interpreting autonomic tests. The unique aspect of this book is the use of the skin biopsies for assessment of small autonomic and sensory fibers as a routine part of autonomic testing. Another important feature of this book is the use of continuous cerebral blood flow velocity and end tidal CO2 monitoring in addition to standard heart rate and blood pressure recordings during the testing. Comprised of 100 unique case studies, each case solves a particular clinical question. The presented cases include neurally mediated syncope, psychogenic pseudosyncope, orthostatic intolerance syndromes, autonomic failure, variety of small fiber neuropathies (with and without autoimmunity), autonomic dysfunction in neurodegenerative and hypermobile disorders.

Book Description
The Director of this study, Abraham Kagan, has comprehensively summarized the design and main finndings of the study in this book. The Honolulu Heart Program compared and contrasted ethnic Japanese men living in different cultural environments--Honolulu and mainland Japan--assessed their relative risk factors. The study supported many of the existing views on risk factors but also showed suprising trends. One of the trends shows moderate alcohol consumption is a preventative factor. In recent years the risk factors for cardiovascular diseases have become common knowledge. The recently completed Honolulu Heart Program is the largest targeted study to evaluate scientifically such risk factors.
