The bill reauthorizes Public Law 106-113 for Fiscal Years 2011-2015 and expands the program to include diagnostic services among the services provided to newborns and infants.
Dr. Battey received his Bachelor of Science degree in physics from the California Institute of Technology in 1974 and earned his M.D. and Ph.D. in biophysics from Stanford University School of Medicine in 1980. Following residency training in pediatrics at Stanford, he received postdoctoral training in genetics at Harvard Medical School under the direction of the eminent scientist Dr. Philip Leder.
Dr. Battey has contributed significantly to several areas of molecular neurobiology and genetics. Now in his third decade at the NIH, he previously served as an investigator and section chief at the National Cancer Institute and the National Institute of Neurological Disorders and Stroke. He came to the NIDCD as director of intramural research in 1995 and chief of the Laboratory of Molecular Biology the following year. He was appointed director of the NIDCD in 1998 – 10 years after the institute was established.
Dr. Battey has established a strong and strategic focus at the NIDCD in both intramural and extramural programs. He is strongly committed to training and supporting new investigators. Under his leadership, the NIDCD has pioneered new training programs and implemented initiatives to expedite the review and funding of fellowship applications, as well as grant applications for investigators applying for their first R01. Under Dr. Battey’s leadership, the NIDCD has built a broad research portfolio in hearing aids and cochlear implants, newborn hearing screening, genetics of communication disorders, and accessible and affordable hearing health care.
In addition to his role as administrator, Dr. Battey was appointed to chair the NIH Stem Cell Task Force by NIH Director, Elias A. Zerhouni, in September 2002. In March 2007, Dr. Battey began serving as Vice Chair of the Task Force.
During his scientific career, Dr. Battey authored or co-authored over 130 papers and is the co-author of a popular laboratory manual on molecular biology. The U.S. Public Health Service honored him with its Commendation Medal in 1990 and, in 1994, the Outstanding Service Medal. In 2007, he was honored as the first recipient of the Distinguished Service Award from the Association for Chemoreception Sciences (AChemS), an international body of scientists that advances understanding of the senses of taste and smell. The award recognizes individuals “with a record of outstanding service to the chemical senses research community.” He received a similar award for research excellence from the Hearing Loss Association of America in 2011, and he is the recipient of three NIH Director’s Awards.

NIDCD supports and conducts research and research training in the normal and disordered processes of hearing, balance, taste, smell, voice, speech, and language through a program of grants and contracts in basic, clinical, and translational research. The Institute also conducts and supports research and research training related to disease prevention and health promotion; addresses special biomedical and behavioral problems associated with communication disorders; and supports efforts to create devices that substitute for lost and impaired sensory and communication function. Research is conducted in public and private institutions across the country and around the world and within the laboratories and clinics at the National Institutes of Health in Bethesda, MD.
The Division of Intramural Research (DIR) conducts basic and clinical research in human communication disorders, with a primary interest in hearing and balance. Current projects address areas such as: disorders of hearing, balance, speech, and language in human and mouse models; identifying molecules and pathways important for the development, structure, and function of the inner ear, and its connection with nerve cells; characterizing the molecular and cellular mechanisms of loss of hearing or balance cause by genetic mutations or non-genetic factors such as noise or drugs; and exploring new and improved methods to detect, diagnose, prevent, and treat hearing and balance disorders. In addition, the DIR hosts the Otolaryngology Surgeon-Scientist Program (OSSP), a mentored career development program for junior faculty. The OSSP trains otolaryngology surgeon-scientists to conceive, develop, and test novel diagnostic and therapeutic strategies through translational research that bridges basic science, medicine, and surgery. Current OSSP research programs focus on a wide range of translational topics, including gene therapy targeting the inner ear, auditory development and regeneration, minimizing chemotherapy-induced hearing loss, and tumor immunology.
The NIDCD’s extramural program supports research and training opportunities at universities, medical centers, and other institutions throughout the U.S. and abroad through research grants, career development awards, and other mechanisms. Our extramural research and training programs are administered through the Division of Scientific Programs (DSP) and the Division of Extramural Activities (DEA).
DEA staff provide grant management and processing for all of the Institute’s extramural research projects and conduct initial scientific merit review of a large array of grant mechanisms. Staff coordinate a broad range of activities and functions to ensure sound and efficient scientific review and financial management of extramural program activities. DSP staff provide leadership and advice in developing, implementing, and coordinating extramural programs and policies. In DSP, scientific program staff plan and direct NIDCD’s extramural research grants, career development awards, individual and institutional research training awards, center grants, and contracts to public and private research institutions and organizations across the country and around the world.
The Office of Health Communications and Public Liaison (OHCPL) disseminates information about NIDCD research support and results, health information, and NIDCD programs to the media, patients and the public, health professionals, scientists, industry, policymakers, and others. OHCPL manages the NIDCD Information Clearinghouse as well as the institute’s public education campaign, It’s a Noisy Planet. Protect Their Hearing®, which aims to increase awareness among children ages 8 to 12 and their parents and caregivers about noise-induced hearing loss and how to prevent it. The Science Policy and Planning Branch also supports educational and awareness efforts through congressional briefings and partnerships with professional societies and advocacy groups.
Hearing and Balance
Hearing and balance disorders decrease the quality of life, cross all ethnic and socioeconomic lines, and impose significant social and economic burden upon individuals, their families, and the communities in which they live. Millions of Americans experience a hearing or balance disorder at some point in their life, especially as young children or older adults. Common examples include otitis media (middle ear infections), noise-induced hearing loss, tinnitus (ringing or buzzing in the ear), age-related hearing loss, dizziness, and vertigo. Nearly 25 percent of Americans aged 65 to 74, and 50 percent of those who are 75 and older, have disabling hearing loss. Nearly 15 percent of adults in the U.S. report experiencing a problem with dizziness or balance during the past 12 months.
The NIDCD Hearing and Balance Program comprises over half of NIDCD’s research portfolio. To study normal and disordered functions of the auditory and vestibular systems, the NIDCD supports a wide range of research approaches including molecular genetics, cellular biology, animal models, biomedical imaging, nanotechnology, psychoacoustics, and structural and functional biology.
To understand the basis of auditory function and dysfunction, animal models are being used to study the function of the proteins encoded by deafness genes, to test possible therapies for hearing impairment, and to screen potential therapeutic drugs. In addition, scientists use animal models to study the properties of auditory sensory cells and the characteristics of the response of the inner ear to sound.
Improving hearing health for all ages has been an ongoing priority for the NIDCD. The NIDCD continues to support research to develop new approaches, assessment methods, and technologies to improve the prevention, diagnosis and treatment of hearing and balance disorders. NIDCD also seeks research to improve access and affordability of hearing health care. Clinical studies and clinical trials include developing and/or enhancing devices to improve or enable hearing or enable the sense of sound, such as hearing aids, cochlear implants, auditory brainstem implants (ABI), as well as their associated habilitation/rehabilitation needs.
Research demonstrates that infants who are born deaf or hard-of-hearing have a better chance of learning language if the hearing loss is identified immediately after they are born and if they learn a spoken or signed language as early as possible. The NIDCD has placed a high priority on understanding the causes, possible treatments, and progression of hearing loss during early childhood. Two to three out of 1,000 babies born in the U.S. each year have a detectable hearing loss that can affect their speech and language, as well as their social and cognitive development. In 1989, less than five percent of newborns received hearing screening prior to leaving the hospital, and most children were not identified to have a hearing impairment until two to three years of age. That delay during a critical period for language development led to lifelong difficulties in language acquisition and the need for costly special education in schools for the deaf. The implementation of universal newborn hearing screening, a joint effort by the NIDCD, HRSA, and the CDC, has dramatically improved the identification of infants with hearing loss early in life and accelerated the initiation of services for these children. Today, more than 98 percent of children born in the U.S. are screened for hearing loss annually which allows for early intervention for these infants.
Throughout the years, NIDCD has also supported new technologies for the treatment of hearing loss. This includes research to improve cochlear implant and hearing aid technology. In addition, advances are being made in developing brainstem implants and brain-computer interfaces to aid those with communication disorders. Such technology has made significant impact in the outcome of those with communication disorders as evidenced by the marked improvement in speech perception and production by most children who received cochlear implants early in life.
Studies concerning the encoding of complex signals transmitted from the auditory nerve to the brain are also supported by NIDCD. The relationship between the neural codes for sound intensity, frequency, duration and temporal characteristics of auditory signals and the perception of the stimulus variables has been further clarified and progress has been made in understanding the structure and function of efferent feedback pathways to the inner ear. Evidence suggests that the efferent system may aid in the detection of signals in noisy environments and serve to protect the ear from acoustic injury. Acoustic injury due to noise, including noise damage to the hair cell afferent synapse, is also an area of active research by NIDCD-supported scientists.
Tinnitus is a ringing in the ears lasting at least five minutes in the past year and is a hearing disorder that affects approximately 25 million Americans, including many military service personnel returning from active duty. Its severity can range from a mild condition, which requires no intervention, to a severe debilitating disease with significant emotional, social, and economic impact. NIDCD research aims to determine the neural basis of tinnitus, and to develop effective interventions for individuals with this disorder.
In the aging auditory system, discoveries have been made demonstrating changes in the regulation of fluid composition and autoregulation of cochlear blood flow which may underlie some of the biologic effects of aging on auditory function. Improved behavioral and electrophysiological techniques for measuring auditory function are providing more accurate assessments of the peripheral and central components of age-related hearing loss.
Otitis media continues to be a significant focus of NIDCD research because of its prevalence and societal cost. Important risk factors for otitis media have been identified, and studies of the eustachian tubes have provided new information on tubal mechanics, surfactant-like (fluid) substances, and middle ear pressure regulation. The role of bacterial biofilms in chronic otitis media is a promising area of investigation. State-of-the-art molecular, genetic, and genomic techniques are being used to identify genes that may predispose an individual to chronic otitis media. These techniques are also being used to define the specific molecular changes that allow viral and bacterial infection of the middle ear as well as the host/pathogen interactions that facilitate the disease process.
Recent development of animal models for bacterial and viral infections hold promise for new diagnostic and therapeutic approaches to sensorineural hearing loss caused by infections. Antiviral drugs may find rapid application in the treatment for these conditions with the advent of suitable animal models in which to test efficacy. In addition, models allow a greater understanding of why and to what degree infants and children are susceptible to ototoxic drugs used in the treatment of infections.
The NIDCD also supports research on the vestibular system. The vestibular system, with its receptor organs located in the inner ear, plays an important role in the maintenance of one's orientation in space, the control of balance while the body is immobile and in motion, and visual fixation of objects during head movement. Vestibular disorders affect a large proportion of the population, particularly the elderly and can result in symptoms of imbalance, vertigo (the illusion of motion), disorientation, instability, falling and visual blurring (particularly during motion). Deficits in vestibular function result from diverse disease processes, including infection, trauma, toxicity, impaired blood supply, autoimmune disease, impaired metabolic function and tumors.
In addition to its role in the stabilization of gaze and balance, recent findings from NIDCD-supported studies suggest that the vestibular system plays an important role in regulating blood pressure. The information emerging from these studies holds potential clinical relevance for the understanding and management of orthostatic hypotension (lowered blood pressure related to a change in body posture).
To better understand the role of the vestibular system, NIDCD supports research to develop and refine tests of balance and vestibular function. Computer-controlled systems measuring eye movement and body postural responses activated by stimulating specific parts of the vestibular sense organ and nerve have been developed and validated for clinical use. Also, tests of functional disability and physical rehabilitative strategies currently being applied in clinical and research settings will have important implications for refining the rehabilitation of individuals with balance and vestibular disorders.
Recently, a prototype vestibular neural prosthesis has been developed by a team of NIDCD-funded investigators. Early-stage studies with this device demonstrates that the function of the inner ear balance system can be partially restored through electrostimulation of the vestibular nerve. Research is progressing in earnest to refine the vestibular prosthesis and to determine its viability for application to individuals with balance and vestibular disorders.
Taste and Smell
The NIDCD supports studies of the chemical senses—taste, smell, and chemethesis (chemically provoked irritation)—to understand how individuals communicate with their environment and how human chemosensory disorders can be diagnosed and treated.
Smell and taste receptor cells are continually replaced throughout life and are replaced rapidly in response to injury such as exposure to pollutants and airborne toxins. These are the only known mammalian sensory cells with this native regenerative capability. The NIDCD supports studies on the process of receptor cell regeneration, including those focused on stem cell differentiation and maintenance.
The regenerative capability of the olfactory system declines with age, with important consequences for our increasingly aged population. Researchers estimate that more than one-third of adults over age 70 have olfactory deficits. Since both taste and smell contribute to flavor, olfactory deficits affect the flavor of foods and consequently food intake, diet, and health status. The NIDCD encourages studies of this age-related decline in olfactory sensitivity, including the development of better diagnostic tests and animal models for use in studying why this decline occurs and how to prevent it.
Great advances have been made in understanding how receptors cells detect chemical cues and how this information is transmitted to the brain. The NIDCD supports molecular and cellular studies of the peripheral mechanisms underlying chemosensation, including studies aimed at characterizing vertebrate and invertebrate chemoreceptors with respect to their structure, function, signaling pathways, patterns of gene expression, and regulation.
NIDCD-supported scientists are studying the central processing of chemosensory information including the underlying neural circuitry of central olfactory and gustatory brain regions and how these circuits fail in pathology. NIDCD investigators have been at the forefront of developing and applying state-of-the-art recording, imaging, computational, and behavioral approaches to examine neural circuit function in awake, behaving animals. Current NIDCD-funded studies are examining the development and plasticity of neural circuits, the functions and connectivity of cortical structures that interpret chemical senses information, the complex multisensory aspects of flavor perception, and the top-down modulation of sensory input and ways in which this is shaped by motivational or cognitive factors.
The NIDCD supports clinical chemosensory research for improved diagnosis, prevention, and treatment of chemosensory disorders. Additional clinical and epidemiological studies will allow researchers to better understand the effects of factors such as diet, early dietary experiences, individual genetic variation, aging, infection, and disease on chemosensory sensitivities and to link chemosensory deficits to other clinical disorders.
Voice, Speech, and Language
Disorders involving voice, speech, or language can have an overwhelming effect on an individual’s health and quality of life. These disorders affect people of all ages with or without hearing impairment, including children with autism, those who stutter, and adults with aphasia or speech disorders. Nearly eight percent of children ages 3-17 years have had a communication disorder during the past 12 months, according to data from the 2012 National Health Interview Survey. By the first grade, roughly five percent of children have noticeable speech disorders. In children, delayed speech and language acquisition or impairment are very often significant predictors of future academic, social, vocational, and adaptive outcomes. Further, an estimated 17.9 million U.S. adults ages 18 or older, or 7.6 percent, report having had a problem with their voice in the past 12 months.
The NIDCD Voice, Speech, and Language Program utilizes a wide range of research approaches to develop effective diagnostic and intervention strategies for individuals with communication impairments. Research in Voice and Speech includes studies to determine the nature, causes, treatment, and prevention of disorders of motor speech production throughout the lifespan. Language research includes the exploration of the genetic bases of child speech and language disorders, as well as characterizing the linguistic and cognitive deficits in children and adults with language disorders.
NIDCD supports several animal research studies investigating the feasibility of using muscle stem cells and novel bioengineering approaches to deliver growth factors to injured laryngeal nerves to encourage reinnervation and restoration of laryngeal muscle function. This will have direct relevance towards creating a more practical treatment strategy for human disorders, including treatment of laryngeal paralysis and other peripheral nerve injuries.
Other NIDCD-supported studies demonstrated that children with developmental speech and language problems are at a considerable risk for learning disabilities and other psychosocial problems that emerge during adolescence or adulthood.
Researchers are learning how reflux from the stomach to the throat and vocal fold tissue harms the larynx. They have demonstrated that reflux significantly alters the expression of 27 genes that are associated with malignant changes of the larynx. Understanding how changes in gene expression lead to laryngeal injury provides a comprehensive model for identifying novel diagnostic and therapeutic targets to treat reflux-related injury.
Investigators are actively working to provide locked-in individuals with a direct means of producing speech to allow rapid communication between the individual and care givers as well as control of computers. This will be accomplished through the development of a direct brain-to-speech generator for use in humans which will use an individual's neural signals.
Language research continues to expand the understanding of the role of each hemisphere of the brain in communication and language, of early specialization of the brain, and of the recovery process following brain damage. This research will further our understanding of the neural bases of language disorders. Research on acquisition, characterization and utilization of American Sign Language is expanding knowledge of the language used by many individuals who are deaf.
Language researchers supported by the NIDCD are also exploring the genetic bases of child language disorders, as well as characterizing the linguistic and cognitive deficits in children and adults with language disorders. Researchers are developing effective diagnostic and intervention strategies for children with autism spectrum disorder, or who have specific language impairment, as well as adults with aphasia.
The NIDCD is committed to building and expanding its clinical trials program to promote the development of interventions to treat or prevent communication disorders in the areas of hearing, balance, taste, smell, voice, speech, and language. The NIDCD has a longstanding history of funding research in the basic sciences in all of these areas and encourages the transition from basic science discoveries to clinical trials and other patient-oriented research.
Clinical research supported by the NIDCD must meet high standards of scientific rigor in both how the study is designed and how it is carried out and maintained. The safety of volunteer participants is the highest priority.
Epidemiology and Statistics
NIDCD supports epidemiological (clinical) and population-based research studies in all seven mission areas of the Institute: hearing, balance, taste, smell, voice, speech, and language. Studies assess impairments of hearing and other communication disorders across the lifespan, including risks associated with other health conditions as well as behavioral, demographic, environmental, and genetic factors. The research studies supported include longitudinal cohort studies, population-based health interview or examination cross-sectional surveys, and case-control studies, such as community-based and nationally-representative health interview and examination surveys to advance knowledge of the prevalence and determinants of communication disorders. The NIDCD maintains research collaborations on national health interview and examination surveys with other Federal agencies and with academic and private sector organizations via research contracts or interagency agreements, including collaboration on the Early Childhood Longitudinal Study-Birth Cohort: 2001 and Kindergarten Cohort: 2010/2011, which have been sponsored by the National Center for Education Statistics, Department of Education. NIDCD epidemiologists have contributed to the analysis and interpretation of trends for the Hearing Health Promotion, Office of the Secretary, Department of Health and Human Services, Healthy People 2010 initiative as well as development of Healthy People 2020, which incorporates health objectives for all seven mission areas of the NIDCD. Consultation on the design and analysis of studies of therapeutic interventions, disease prevention or progression, and environmental or genetic causes are provided. In addition, statistical methods are developed and data systems supported for the purpose of tracking prevalence rates and estimating relative and attributable risks.
