Neurobiology Of Epilepsy And Aging

This volume in the International Review of Neurobiology series addresses the epidemiology, pathophysiology, and treatment of epilepsy in elderly patients. Demographically, the elderly comprise both the fastest-growing segment of the U.S. population and the adult age group with the highest incidence of epilepsy, yet there are relatively few publications devoted to this clinical subgroup. The intersection of these two complex processes—epilepsy and advancing age—will have an increasing impact on medical and community care. The etiology, prognosis, and differential diagnosis of epilepsy can all be affected by the normal aging process and by the frequent comorbidities encountered in an elderly population. Chapters in this book review the effects of aging on brain function and on drug metabolism and interactions, covering the gamut of research from animal models of aging and epilepsy to clinical trials and outcomes. Topics also include the dangers of misdiagnosing status epilepticus, the special issues encountered in recruiting and retaining elderly clinical trial participants, and the use of antiepileptic drugs in the elderly. In both the clinic and the research laboratory, a better understanding of how epilepsy may differ between younger and older patients will be valuable in determining the best possible care for geriatric patients with epilepsy.

With the aging of the baby boomers and medical advances that promote longevity, older adults are rapidly becoming the fastest growing segment of the population. As the population ages, so does the incidence of age related disorders. Many predict that 15% - 20% of the baby-boomer generation will develop some form of cognitive decline over the course of their lifetime, with estimates escalating to up to 50% in those achieving advanced age. Although much attention has been directed at Alzheimer’s disease, the most common form of dementia, it is estimated that nearly one third of those cases of cognitive decline result from other neuropathological mechanisms. In fact, many patients diagnosed with Alzheimer’s disease likely have co-morbid disorders that can also influence cognition (i.e., vascular cognitive impairment), suggesting mixed dementias are grossly under diagnosed. The Clinical Handbook on the Neuropsychology of Aging and Dementia is a unique work that provides clinicians with expert guidance and a hands-on approach to neuropsychological practice with older adults. The book will be divided into two sections, the first addressing special considerations for the evaluation of older adults, and the second half focusing on common referral questions likely to be encountered when working with this age group. The authors of the chapters are experts and are recognized by their peers as opinion leaders in their chosen chapter topics. The field of neuropsychology has played a critical role in developing methods for early identification of late life cognitive disorders as well as the differential diagnosis of dementia. Neuropsychological assessment provides valuable clinical information regarding the nature and severity of cognitive symptoms associated with dementia. Each chapter will reinforce the notion that neuropsychological measures provide the clinician with sensitive tools to differentiate normal age-related cognitive decline from disease-associated impairment, aid in differential diagnosis of cognitive dysfunction in older adults, as well as identify cognitive deficits most likely to translate into functional impairments in everyday life.

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.

Jasper's Basic Mechanisms, Fourth Edition, is the newest most ambitious and now clinically relevant publishing project to build on the four-decade legacy of the Jasper's series. In keeping with the original goal of searching for "a better understanding of the epilepsies and rational methods of prevention and treatment.", the book represents an encyclopedic compendium neurobiological mechanisms of seizures, epileptogenesis, epilepsy genetics and comordid conditions. Of practical importance to the clinician, and new to this edition are disease mechanisms of genetic epilepsies and therapeutic approaches, ranging from novel antiepileptic drug targets to cell and gene therapies.

What are the boundary zones between normal aging and Alzheimer's disease (AD)? Are many elderly people whom we regard as normal actually in the early stages of AD? Alzheimer's disease does not develop overnight; the early phases may last for years or even decades. Recently, clinical investigators have identified a transitional condition between normal aging and and very early Alzheimer's disease that they have called mild cognitive impairment, or MCI. This term typically refers to memory impairment beyond what one would expect in individuals of a given age whose other abilities to function in daily life are well preserved. Persons who meet the criteria for mild cognitive impairment have an increased risk of progressing to Alzheimer's disease in the near future. Though many questions about this condition and its underlying neuropathology remain open, full clinical trials are currently underway worldwide aimed at preventing the progression from MCI to Alzheimer's disease. This book addresses the spectrum of issues involved in mild cognitive impairment, and includes chapters on clinical studies, neuropsychology, neuroimaging, neuropathology, biological markers, diagnostic approaches, and treatment. It is intended for clinicians, researchers, and students interested in aging and cognition, among them neurologists, psychiatrists, geriatricians, clinical psychologists, and neuropsychologists.

Neurobiology of Epilepsy: From Genes to Networks is the latest volume in the Progress in Brain Research series that focuses on new trends and developments. This established international series examines major areas of basic and clinical research within the neurosciences, as well as popular and emerging subfields. Explores new trends and developments in the neurobiology of Epilepsy Enhances the literature of neuroscience by further expanding the established, ongoing international series Progress in Brain Research Examines major areas of basic and clinical research within the field

This volume makes clear that the cognitive and behavioural symptoms of neurologic disorders and syndromes are dynamic and changing. Each chapter describes the neuroplastic processes at work in a particular condition, giving rise to these ongoing cognitive changes.
