Book Description
This volume brings together noted scientists who study presbycusis from the perspective of complementary disciplines, for a review of the current state of knowledge on the aging auditory system. Age-related hearing loss (ARHL) is one of the top three most common chronic health conditions affecting individuals aged 65 years and older. The high prevalence of age-related hearing loss compels audiologists, otolaryngologists, and auditory neuroscientists alike to understand the neural, genetic and molecular mechanisms underlying this disorder. A comprehensive understanding of these factors is needed so that effective prevention, intervention, and rehabilitative strategies can be developed to ameliorate the myriad of behavioral manifestations.

Book Description
Age-related declines in hearing abilities are common and can be attributed to changes in the peripheral and central levels of the auditory system. Although central auditory processing is enhanced in younger musicians, the influence of lifelong musicianship on age-related decline in central auditory processing has not yet been investigated. Therefore, the purpose of this dissertation was to investigate whether lifelong musicianship can mitigate age-related decline in central auditory processing. In the first experiment, age-related declines on four hearing assessments were compared between musicians and non-musicians. Speech-in-noise and gap-detection thresholds were found to decline at a slower rate in musicians, providing an increasing advantage with age. Furthermore, musicians had a lifelong advantage in detecting a mistuned harmonic, although the rate of age-related decline was similar for both musicians and non-musicians. Importantly, there was no significant effect of musicianship on pure-tone thresholds, suggesting that lifelong musicianship can mitigate age-related decline in central but not peripheral auditory processing. To test this hypothesis, a second experiment compared auditory evoked responses (AERs) between groups of older and younger musicians and non-musicians. Results indicated that exogenous neural activity was enhanced in musicians, but that age-related changes were similar between musicians and non-musicians. Furthermore, endogenous, attention-dependent neural activity was enhanced in older adults, suggesting a compensatory cognitive strategy. Importantly, endogenous activity was preferentially enhanced in older musicians, suggesting that lifelong musicianship enhanced cognitive processes related to auditory perception. In the final experiment, the ability to segregate simultaneous sounds was tested in older and younger musicians and non-musicians by using a mistuned harmonic paradigm, where AERs to harmonic complexes were compared to AERs when one of the harmonics was mistuned. Results indicated that musical training in older adults has little effect on early automatic registration of the mistuned harmonic. In contrast, late attention-dependent activity, associated with the perception of the mistuned harmonic as a separate sound, was influenced by musical training in older adults, suggesting that lifelong musicianship preserves or enhances cognitive components of concurrent sound segregation. In summary, musical training was found to reduce age-related decline in hearing abilities due to enhanced central processing of auditory information.

Book Description
It has become accepted in the neuroscience community that perception and performance are quintessentially multisensory by nature. Using the full palette of modern brain imaging and neuroscience methods, The Neural Bases of Multisensory Processes details current understanding in the neural bases for these phenomena as studied across species, stages of development, and clinical statuses. Organized thematically into nine sub-sections, the book is a collection of contributions by leading scientists in the field. Chapters build generally from basic to applied, allowing readers to ascertain how fundamental science informs the clinical and applied sciences. Topics discussed include: Anatomy, essential for understanding the neural substrates of multisensory processing Neurophysiological bases and how multisensory stimuli can dramatically change the encoding processes for sensory information Combinatorial principles and modeling, focusing on efforts to gain a better mechanistic handle on multisensory operations and their network dynamics Development and plasticity Clinical manifestations and how perception and action are affected by altered sensory experience Attention and spatial representations The last sections of the book focus on naturalistic multisensory processes in three separate contexts: motion signals, multisensory contributions to the perception and generation of communication signals, and how the perception of flavor is generated. The text provides a solid introduction for newcomers and a strong overview of the current state of the field for experts.

Book Description
Since the first edition of the Aging Auditory System volume (in 2009), there has been a tremendous amount of research in basic, translational, and clinical sciences related to age-related changes in auditory system structure and function. The new research has been driven by technical and conceptual advances in auditory neuroscience at multiple levels ranging from cells to cognition. The chapters in Aging and Hearing: Causes and Consequences span a broad range of topics and appeal to a relatively wide audience. Our goal in this volume is to put together state-of-the-art discussions about new developments in aging research that will appeal to a broad audience, serving as an important update on the current state of research on the aging auditory system. This update includes not only the recent research, but also consideration of how human and animal studies or translational and basic research are working in tandem to advance the field. This new edition is a natural complement to the previous SHAR volume on the aging auditory system edited by Gordon-Salant, Frisina, Popper, and Fay. The target audience for this volume will be graduate students, researchers, and academic faculty from a range of disciplines (psychology, hearing science/audiology, physiology, neuroscience, engineering). It also will appeal to clinical audiologists as well as to researchers working in the hearing device industry. Individuals who attend conferences sponsored by the Association for Research in Otolaryngology, Acoustical Society of America, Auditory Cognitive Neuroscience Society, American Auditory Society, Society for Neuroscience, American Speech, Language and Hearing Association, and the American Academy of Audiology (among others) are likely to find value in the volume.

Book Description
Binaural interference occurs when the speech input to one ear interferes with the input to the other ear during binaural stimulation. The first published study on binaural interference twenty-five years ago demonstrated that some individuals, particularly older individuals, perform more poorly with two hearing aids than with one and/or more poorly with binaural than monaural stimulation on electrophysiologic as well as behavioral measures. Binaural interference is relevant to every audiologist because it impacts the successful use of binaural hearing aids and may explain communicative difficulty in noise or other challenging listening situations in persons with normal-hearing sensitivity as well as persons with hearing loss. This exciting new book written by two highly respected audiologists first traces the history of its study by researchers, then reviews the evidence, both direct and indirect, supporting its reality. This is followed by a discussion of the possible causes of the phenomenon and in-depth analysis of illustrative cases. The authors outline a systematic approach to the clinical detection, evaluation and amelioration of individuals who exhibit binaural interference. Suggestions are furnished on improved techniques for evaluation of the binaural advantage in general and on sensitized detection of the disorder in particular. The book ends with recommendations for future directions. Given the adverse impact of binaural interference on auditory function and its occurrence in a significant subset of the population with hearing loss, as well as in some individuals with normal-hearing sensitivity, research on binaural interference only recently has begun to flourish, and adaptation of audiologic clinical practice to identify, assess, and manage individuals with binaural interference has yet to become widespread. The authors intend for the book to provide impetus for pursuing further research and to encourage audiologists to explore the possibility of binaural interference when patient complaints suggest it and when performing audiologic evaluations. The book is intended for practicing clinical audiologists, audiology students, and hearing scientists.

Book Description
Communication and Swallow Changes in Healthy Aging Adults compiles and presents the available research on healthy aging adults’ performance and abilities in the following areas: auditory comprehension, reading comprehension, speaking, writing, voice and motor speech abilities, cognition, and swallowing. This text also presents principles from the World Health Organization’s International Classification of Functioning, Disability and Health and its applications to aging adults. One of the first texts to cover these principles, this book will address the need for a comprehensive view of communication and swallow issues in aging for students of speech-language pathology. Speech-language pathologist students will learn how to fully compare what would be considered normal for their elderly patients rather than overestimating or underestimating what aging adults are capable of doing. Knowing what would be considered within the spectrum of normal, will help speech-language pathologists to address therapy as effectively as possible. Having this information at hand is particularly important as the nation’s population is aging at a rapid rate and there is a need for evidence-based practice in speech-language pathology. Written in an easy to follow format, Communication and Swallow Changes in Healthy Aging Adults includes original research data, discussion questions and a list of Quick Facts at the end of each chapter to summarize key points. This text will serve as a useful resource as students see elderly clients in on-campus speech and hearing clinics and when they intern at hospitals and long-term care facilities. Instructor Resources: PowerPoint Slides and an Image Bank Testimonial: “Communication and Swallowing Changes in Healthy Aging Adults is a handy text, portable, and logically organized. The information is easy to follow complimented by information presented in tables/charts. This text would be helpful to a practicing therapist when making a differential diagnosis between a normal vs. atypical aging process. Communication and Swallowing Changes in Healthy Aging Adults would be an appropriate text for courses in Communications Disorders Departments for graduate students in a neuro course or a neurogenic communication disorders course, and in lifespan development courses as in the field of Psychology and Gerontology.” ~ Susan Durnford, M.S.,CCC-SLP, Clinical Assistant Professor, Department of Speech-Language Pathology & Audiology, Ithaca College

Book Description
We live in an aging world. Illnesses that are prevalent and cause significant morbidity and mortality in older people will consume an increasing share of health care resources. One such illness is depression. This illness has a particularly devastating impact in the elderly because it is often undiagnosed or inadequately treated. Depression not only has a profound impact on quality of life but it is associated with an increased risk of mortality from suicide and vascular disease. In fact for every medical illness studied, e.g. heart disease, diabetes, cancer, individuals who are depressed have a worse prognosis. Research has illuminated the physiological and behavioral effects of depression that accounts for these poor outcomes. The deleterious relationship between depression and other illnesses has changed the concept of late-life depression from a "psychiatric disorder" that is diagnosed and treated by a psychiatrist to a common and serious disorder that is the responsibility of all physicians who care for patients over the age of 60.This is the first volume devoted to the epidemiology, phenomenology, psychobiology, treatment and consequences of late-life depression. Although much has been written about depressive disorders, the focus has been primarily on the illness as experienced in younger adults. The effects of aging on the brain, the physiological and behavioral consequences of recurrent depression, and the impact of other diseases common in the elderly, make late-life depression a distinct entity. There is a compelling need for a separate research program, specialized treatments, and a book dedicated to this disorder. This book will be invaluable to psychiatrists, gerontologists, clinical psychologists, social workers, students, trainees, and others who care for individuals over the age of sixty.
