Physical Activity and the Aging Brain: Effects of Exercise on Neurological Function is a complete guide to the manifold effects of exercise and physical activity on the aging brain. Cognitive decline and motor impairment, onset of diseases and disorders, and even changes in family structure and social settings that occur as we age can all impact activity levels, yet continued physical activity is crucial for successful neurological functioning. This book examines the role that exercise and physical activity play in halting or modulating the deleterious effects of these numerous aging concerns by first examining the current state of research into how exercise manifests physical changes in the brain. It then discuss how physical activity combines with other lifestyle factors to benefit the aging brain, including nutrition, computerized brain training, and social engagement. Most significantly, it also covers how physical activity can serve as therapy to help alleviate the symptoms of various neurological diseases impacting aging populations, with particular emphasis on Alzheimer’s disease and age-related cognitive decline. The book provides broad coverage of the effects of exercise and physical activity on the aging brain, its therapeutic effects, and the many factors that influence the aging process. Presents research scientists with a complete understanding of the role of exercise in healthy brain aging Considers the roles of nutrition, the mind-body connection, and other lifestyle factors Presents a major resource for exercise and physical activity in the neurological health of older adults Provides a synopsis of key ideas associated with the many aspects of physical activity, along with lifestyle factors that can modify neurological diseases and age-related neurological decline

While growing older is inevitable, many of the troubles we associate with aging--including dementia, disability, and an increased dependence on others--are not. The choices we make now can help us to maintain our vitality, a sharp mind, and our independence as we age. Filled with simple, everyday actions we can take to avoid disease, promote vitality, and prevent dementia and late onset Alzheimer's, The Aging Brain is an easy-to-use guide to maintaining brain and body health throughout our lives. Based on solid, up-to-date scientific research, the interventions explained in this book not only prevent progression toward dementia even in those who have already shown mild cognitive impairment, they also reduce disability and depression and keep people living independently longer than those who do not practice these methods. For anyone hoping to slow the aging process, as well as anyone who acts as a caregiver to someone at risk of or already beginning to suffer from dementia and other age-related diseases, this book offers a hopeful, healthy way forward.

The brain is the most complex organ system in the human, both in the intricacy of its cellular architecture and in the extent of its repertoire of macromolecules. The Aging Brain presents the current state of understanding of molecular, cellular, and functional changes that occur in normal brain aging, and compares and contrasts those changes with events occurring in age-related neurodegenerative disorders. The chapters, written by world leaders in the field of brain aging, provide a timely and comprehensive consideration of key areas of this rapidly growing field of aging research. The topics covered include structural, functional, biochemical and molecular changes that occur during usual aging and in age-related neurological disorders. An emphasis is placed on emerging findings at the cellular and molecular levels. The roles of oxidative stress and perturbed energy metabolism in aging and neurodegenrative disorders are covered in considerable detail. In addition, the impact of aging and disease on specific neurotransmitter, neurotrophic factor and cytokine signaling pathways is reviewed. Finally, recent findings concerning possible approaches to reduce risk for age-related neurodegenerative disorders, such as caloric restriction, are presented. The collective body of information presented in The Aging Brain will provide those stepping into the field of brain aging with an overview of our current understanding of fundamental changes that occur in the aging brain, and their molecular and cellular underpinnings. At the same time, the book delves deeply into critical mechanistic details of brain aging that should prove valuable to experts in the field.

The significance of hormone action in psychiatry has been long studied, now including the psychiatric effects of hormones on the aging process. This clinical reference addresses the hormonal basis of mental disorders in older people. Hormones influence a wide range of states and conditions, from pain tolerance and anorexia to attention, mood, immunity, cardiovascular and cognitive function, schizophrenia and Alzheimer's disease. Written by an eminent team of psychiatrists, psychologists, geriatricians and neuropharmacologists, this book brings together established information and findings in four sections: • An overview of the basic science of neurosteroids • Sex difference and the roles that cortisol, thyroid hormone, and the sex steroids estrogen, progesterone, dehydroepiandrosterone and testosterone play in common mental disorders and pain sensitivity • Psychoneuroimmunology in relation to age • Sex differences and hormones in psychotropic drug metabolism in the elderly.

Healthy ageing can lead to declines in both perceptual and cognitive functions. Impaired perception, such as that resulting from hearing loss or reduced visual or tactile resolution, increases demands on ‘higher-level’ cognitive functions to cope or compensate. It is possible, for example, to use focused attention to overcome perceptual limitations. Unfortunately, cognitive functions also decline in old age. This can mean that perceptual impairments are exacerbated by cognitive decline, and vice versa, but also means that interventions aimed at one type of decline can lead to improvements in the other. Just as improved cognition can ameliorate perceptual deficits, improving the stimulus can help offset cognitive deficits. For example, making directions and routes easy to follow can help compensate for declines in navigation abilities. In this Topic, we bring together papers from both auditory and visual researchers that address the interaction between perception and cognition in the ageing brain. Many of the studies demonstrate that a broadening of representations or increased reliance on gist underlie perceptual and cognitive age-related declines. There is also clear evidence that impaired perception is associated with poor cognition although, encouragingly, it can also be seen that good perception is associated with better cognition. Compensatory cognitive strategies were less successful in improving perception than might be expected. We also present papers which highlight important methodological considerations that are required when studying the older brain.

A distinguished panel of internationally recognized neuroscientists comprehensively review the involvement of and changes in glial cells both during the normal aging process and in the major disorders of old age. Topics range from the cellular and molecular changes that occur with aging-especially aging-associated activation of astrocytes and microglia and its relation to neuronal injury and repair-to neuron-glia intercommunication. The contributors show how glial signals may be modulated by hormones, growth factors, neurotransmitters, intracellular metabolism, and intercellular exchanges, as well as by aging of the blood-brain barrier.
