National Institute on Aging (NIA)


NIA was established in 1974 to improve the health and well-being of older adults through research. It conducts and supports genetic, biological, behavioral, social, and economical research on aging and the challenges and needs of older adults. NIA is at the forefront of scientific discovery about the nature of healthy aging to extend the healthy, active years of life. It is also the lead federal agency for Alzheimer’s disease and related dementias research.

NIA supports scientific initiatives and innovation at universities, medical centers, and research institutes across the U.S. and around the world; conducts research at its scientific laboratories in Baltimore and Bethesda, Maryland; and maintains an active communications and outreach program to share knowledge and disseminate information to the broader research community and to the public.

NIA’s work has led to important scientific discoveries about the aging process, age-related diseases and conditions, and the needs of the growing older adult population.

Research Programs

Intramural Research

Laboratory of Cardiovascular Science (LCS)

LCS goals are to: 1) identify age associated changes that occur within the cardiovascular system and to determine the mechanisms for these changes; 2) determine how aging of the heart and vasculature interacts with chronic disease states to enhance the risk for CV diseases in older persons; 3) study basic mechanisms in excitation-contraction coupling and how these are modulated by surface receptor signaling pathways in cardiac cells; 4) elucidate mechanisms of pacemaker activity in sinoatrial nodal cells; 5) elucidate mechanisms that govern cardiac and vascular cell survival; and 6) establish the potentials and limitations of new therapeutic approaches such as changes in lifestyle, novel pharmacologic agents or gene or stem cell transfer techniques in aging or disease states.

Laboratory of Molecular Biology and Immunology (LMBI)

The unifying theme of LMBI's research program is to uncover molecular mechanisms that are pertinent to understanding and ameliorating age-associated disabilities and diseases, with emphasis on changes in the immune system. Programs cover fundamental biological questions such as: 1) the study of gene regulatory mechanisms that mediate cellular responses to developmental signals, immune activation and stress stimuli; 2) induction of effective immune responses, including the mechanisms of class switch recombination and somatic hypermutation, and generation and maintenance of memory; 3) the role of telomere length and telomerase activity in lymphocyte function and aging; and 4) immune regulatory mechanisms that affect aging. LMBI programs have a strong translational component with studies aimed at improving vaccine efficacy in the elderly and examining the molecular and cellular basis of tumor metastasis. A wide variety of in vitro and in vivo models are employed to approach these issues. LMBI also collaborates with Baltimore Longitudinal Study of Aging researchers to enable direct application of molecular parameters to the human condition.

Laboratory of Clinical Investigation (LCI)

LCI seeks to understand fundamental metabolic processes that change with aging, to elucidate which alterations are pathological and which are homeostatic as humans age. LCI investigators hope to uncover ways to manage and/or circumvent the pathological alterations so that the health of the elderly stays stable. Studies are performed at molecular, cellular, animal model, and human levels. Further, LCI takes a multisystem approach to age-related changes because changes in one system lead to adaptive changes in another. Understanding which are adaptive and which are primary is an intense area of investigation using newly developed multidimensional algorithms and computer programs. The areas of most intense investigation within LCI are pancreatic islet morphology and changes therein with obesity, inflammation, and aging; senescence of stem cells; metabolic perturbations of neurodegeneration; development and validation of blood-based, histological-based and imaging biomarkers of age-related and vascular-related neurodegeneration to inform diagnosis and the testing of potential therapeutic interventions; and development of plant-based compounds as treatments for metabolic conditions. In each of these cases, translational research is far advanced on target compounds that are hypothesized to alter natural history of age-related diseases or are already shown to be beneficial in humans. LCI also carries out proof-of-principle Phase 1 research with index compounds that have been developed in the basic science laboratories.

Laboratory of Epidemiology and Population Sciences (LEPS)

LEPS researchers investigate the causes and consequences of disease and function-specific outcomes that are highly prevalent in the population, with particular focus on those related to aging and health disparities. The laboratory takes a multi-modality and multi-disciplinary approach which includes observational studies, clinical trials, and translational experimental research. Studies are designed to integrate knowledge and identify common behavioral and biologic pathways of disease and function related to the cardiovascular, neuro-cognitive, musculoskeletal, body composition, and metabolic systems, and investigate how these are affected by age, health disparities, socioeconomic status, genetic difference, and modifiable risk factors. Common mechanisms of interest include inflammation, metabolic dysregulation, increase in visceral fat and decrease in muscle mass, elevated blood pressure, and atherosclerosis. Genetic contributions and their interactions with behavioral and physiologic factors are studied in the context of genome wide association study consortia. Efforts also focus on translation to clinical trials of our findings based on observational studies. In addition, LEPS actively investigates state-of-the-art objective measures that can be applied in population-based cohorts. To address these questions, LEPS has developed a large number of well-phenotyped longitudinally followed cohorts, including the Age Gene/Environment-Reykjavik Study (AGES-RS), the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) Study, and the Health and Body Composition Study (HABC).

Laboratory of Genetics and Genomics (LGG)

LGG goals are to understand the genetic and genomic determinants of aging. Researchers investigate the genes and gene expression programs that govern the physiologic declines of aging (e.g., reduced strength, menopause, decreased ability to respond to nutrient imbalances, and diminished immune function) and the increased pathologies of the elderly (e.g., neurodegeneration, cardiovascular disease, diabetes, arthritis, obesity, and cancer). LGG aims include (1) identifying cohorts of genes and mechanisms involved in the development of select non-renewable (and hence aging-prone) cell systems; (2) elucidating genetic factors that determine aging-related traits, rates of aging, and diseases in the population on the island of Sardinia; (3) uncovering multi-protein complexes that mediate the DNA damage response, chromatin remodeling, and RNA metabolism associated with cancer and neurodegeneration; and (4) investigating post-transcriptional gene regulatory processes that affect the normal physiologic decline of aging and the aberrant gene expression programs in age-associated disease.

Laboratory of Molecular Gerontology (LMG)

LMG investigates DNA metabolism including genomic instability, DNA repair, DNA replication, and transcription with special attention to examining the role of DNA damage accumulation in senescence, which is a major cause of aging. Researchers investigate how accumulation of DNA damage with aging leads to senescence, mitochondrial dysfunction, and age-associated disease. LMG has found a signaling pathway from nuclear damage to mitochondrial dysfunction, which seems to be defective in some DNA repair defective disorders including Alzheimer’s disease, and intervention with nicotinamide adenine dinucleotide supplementation has beneficial effects. LMG also investigates the mechanistic role of human premature aging proteins in preventing early aging. Researchers study the mechanism involved in DNA repair of oxidative lesions; and in base excision repair, including the function of individual DNA repair proteins and their protein interactions. LMG also studies proteins and pathways involved in the maintenance of the chromosome ends, the telomeres. Investigators explore how DNA interstrand crosslinks — very detrimental to cells — are removed from DNA and how this relates to age-associated disease. In addition, LMG studies the roles of DNA helicases in genomic stability and conducts translational and intervention studies. Thus, the focus is on genome stability and maintenance and its connection to aging with a view to intervention.

Laboratory of Neurogenetics (LNG)

LNG studies neurodegenerative diseases based on a resolution of their genetic etiology. The Molecular Genetics Section is focused on finding genes for neurodegenerative disease, particularly Parkinson’s disease and related disorders; the Neuromuscular Disease Research Unit works toward an understanding of the genetic basis of neuromuscular disorders including Amyotrophic lateral sclerosis; the Cell Biology & Gene Expression Section seeks to develop an understanding of the effects of mutant genes on cell physiology, including patient derived cells; the Transgenic Unit examines the pathogenesis of neurodegenerative disorders in whole animals and to identify underlying physiological pathways relevant disease risk; and the Molecular Neuropathology Section uses both patient derived material and experimental systems to investigate novel therapeutic approaches across a range of neurodegenerative diseases. Underpinning this structure are three groups: a Computational Biology Core to facilitate the analysis of laboratory data in the broad context of the wealth of information available through the Human Genome Project and related endeavors, a Statistical Genetics Group that uses high volume genetic and other data to derive population level analyses relevant to neurodegenerative diseases, and a Genomic Technologies Group to leverage and support the most recent genomic approaches.

Laboratory of Behavioral Neuroscience (LBN)

LBN conducts basic and clinical research on individual differences in cognition, personality, and affect; investigates the cellular, neural systems, and genetic contributions to variation between individuals in animal models and humans; examines predictors and modifiers of age-related neurodegenerative diseases, cognitive and brain aging, and brain-behavior associations; identifies early markers of Alzheimer’s disease and cognitive decline; examines factors that promote the maintenance of cognitive health; and develops and validates blood-based and imaging biomarkers of age-related neurodegeneration to inform diagnosis elucidate disease mechanisms and identify potential novel therapeutics. Laboratory investigators employ a variety of approaches, including experimental, longitudinal, neuroimaging, biomarker, neuropathological, anatomical, molecular, and genetic methods in the analysis of biological and psychological aspects of aging.

Translational Gerontology Branch (TGB)

TGB is focused on improving the health and well-being of the elderly population through epidemiological, clinical, and basic research programs, with a special emphasis on longitudinal observations and intervention studies. TGB conducts the Baltimore Longitudinal Study of Aging as a part of efforts to investigate and develop novel strategies and interventions to support healthy aging and the prevention or delay of functional decline and age-related diseases. TGB’s main research goals are to: 1) translate discoveries made from human and model organisms to the basic biology (and vice versa), mainstreaming the “bench-to-bedside-to-bench” approach; 2) explore and identify the underlying molecular mechanisms responsible for the functional decline that occurs with age, and 3) develop and test interventions to delay aging processes.

The Center for Alzheimer’s and Related Dementias (CARD)

CARD is a collaborative initiative between NIA and the National Institute for Neurological Disorders and Stroke that supports basic, translational, and clinical research on Alzheimer’s disease and related dementias including vascular dementia, dementia with Lewy bodies, and frontotemporal dementia. CARD’s mission is to initiate, stimulate, accelerate, and support research that will lead to the development of improved treatments for these devastating diseases. The focus is on using a data-driven and collaborative approach that emphasizes robust, replicable findings and open science. Through CARD, NIA supports collaborative work engaging researchers across the NIH Intramural program, government, academia, and industry. CARD researchers will work across scientific domains and disease boundaries to bridge basic, preclinical, and clinical research with particular focus on 1) molecular pathogenesis anchored in genetics, 2) disease subtyping, prediction, and prognosis, 3) de-risking of therapeutic targets and strategies, and 4) precision therapeutics.

DAB chairs the Trans-NIH Geroscience Interest Group (GSIG) that includes representation from 20 NIH Institutes and Centers. Designed as a collaborative framework, GSIG promotes identification of innovative approaches to better understand the relationship between the biological processes of aging and age-related health. GSIG aims to accelerate and coordinate efforts to promote further discoveries on the role of aging processes in the development of chronic diseases and disabilities, with the goal of resolving health problems among our increasingly older population.

Division of Behavioral and Social Research (BSR)

BSR supports basic and translational social, behavioral, psychological, and economic research and research training on the processes of aging at both the individual and societal level. As detailed below, this includes research on behavioral and social pathways to Alzheimer’s disease and related dementias (AD/ADRD) and on the impact on of AD/ADRD on individuals, families, institutions, and societies. BSR fosters cross-disciplinary research on aging and AD/ADRD, at multiple levels of analysis ranging from genetics to cross-national comparative studies, and from a life course perspective. The division supports translational research at all stages, from basic through dissemination and implementation, in line with the NIH Stage Model of Intervention Development.

Individual Behavioral Processes Branch (IBP)

IBP develops and supports research programs with a broad scientific scope on psychological, behavioral, and interpersonal processes of relevance to aging. This includes research on: mechanisms of behavior change and behavioral interventions; cognitive, affective, and social functioning; molecular and behavior genetics; sociogenomics; technology and human factors; family and interpersonal relationships; and integrative biobehavioral research on the mechanistic pathways linking social and behavioral factors to health in mid-life and older age. There is a strong emphasis on life course research, including both early life and midlife causal influences on later life outcomes and trajectories of aging. IBP encourages studies of the life course and aging in humans and in wild and captive animal models. IBP priorities include research on vulnerable populations, under-represented minorities, and the social determinants of health as captured in the NIA Health Disparities Research Framework. Research to elucidate the psychological, behavioral, and interpersonal mechanisms that account for later life health inequalities is particularly encouraged. The branch supports research that is highly interdisciplinary, linking methods and approaches from psychology, anthropology, economics, neuroscience, and genetics.

IBP collaborates with the NIA Division of Neuroscience to encourage research at the intersection of behavior and neuroscience, notably in the areas of cognitive interventions, cognitive epidemiology, decision neuroscience and affective neuroscience. Collaborations with the NIA Division of Geriatrics and Clinical Gerontology include the influence of childhood factors on aging outcomes, as well as research on pain, subjective well-being, and resilience in aging. Collaborations with the NIA Division of Aging Biology center on the extent to which an understanding of behavioral and social processes, including stress reactivity and stress resilience, can provide mechanistic insights into factors that drive biological aging.

IBP manages Resource Centers for Minority Aging Research (RCMAR) to enhance the diversity of the aging research workforce and to increase the number of researchers focused on health disparities and the health and well-being of minority older adults. IBP collaborates with the BSR Population and Social Processes branch in managing the Edward R. Roybal Centers for Translational Research to foster the translation and integration of basic behavioral and social research findings into interventions that will improve the lives of older people and the capacity of institutions to adapt to societal aging.

Population and Social Processes Branch (PSP)

PSP supports research and data infrastructure projects on how demographic, social, economic, institutional, geographic, and other factors at the population level influence health and mortality at older ages. “Health” is broadly defined to include physical and cognitive functioning (including AD/ADRD), disability, morbidity, and well-being. PSP encourages research that develops and uses large diverse nationally representative longitudinal cohort data with measures of early life experiences to study the factors that explain trends, dynamics, and disparities in outcomes across the life course as well as in later life. PSP focal areas include:

  • Elucidating life course pathways leading to health outcomes and disparities.
  • Unpacking socioeconomic status and race/ethnicity as risk factors to better understand the mechanisms by which they produce health and influence disparities in health.
  • International and comparative research to further our understanding of how different social, familial, environmental, geographic, cultural, and institutional contexts influence the aging process, health, and mortality.
  • Understanding the influence of health care services, the health care system, and long-term supports and services on the health and well-being of older persons with chronic disease, disability, and AD/ADRD, as well as their care providers.
  • How environmental, social, economic, institutional, structural, and other factors affect health and well-being, including health-related behaviors, healthcare utilization, health disparities, and responses to public health interventions.
  • Interdisciplinary research with connections to biological, genetic, psychological, behavioral, and interpersonal factors to better understand social and population processes influencing health and aging.
  • Research using a diverse set of analytical approaches, including life cycle, comparative, geographic distribution, rural/urban, cohort, and multi-level.
  • Population-level interventions and pragmatic trials to improve health, health delivery, quality of care, and to reduce health disparities as well as quasi-experimental techniques to identify causal effects where experiments are impractical or infeasible.

PSP manages the Centers on the Demography and Economics of Aging to foster the development of innovative population and social research in aging as well as develop research resources to facilitate aging research. Collaboration with other NIA center programs is encouraged to enhance interdisciplinary research.

Behavioral and Social Research on Alzheimer’s Disease

Within and across the branches, BSR supports research and initiatives on life course familial, social, psychological, behavioral, institutional, and economic factors pertaining to cognitive health and AD/ADRD at both the population and individual levels. BSR is committed to advancing high-caliber science in a variety of disciplines, including demography, lifespan development, psychology, behavioral medicine, behavioral economics, sociology, social and decision neuroscience, health services research, behavioral and population genetics, and social epidemiology to promote the health and wellbeing of persons living with AD/ADRD and their caregivers.

BSR’s AD/ADRD portfolio spans multiple levels from genetics to cross-national comparative research, and all stages from basic through translational. Priority topics include dementia care and long-term services and supports, caregiver research, and caregiving interventions, cognitive and dementia epidemiology, behavioral and social pathways of risk and resilience for AD/ADRD, early psychological and functional changes in AD/ADRD, AD/ADRD prevention and the promotion of long term behavioral and lifestyle change. Throughout these topics, there is a strong focus on health disparities. BSR also develops and supports numerous data and infrastructure resources for AD/ADRD research in the social, behavioral, psychological, and economic sciences.

Data Resources for Behavioral and Social Research on Aging

NIA supports a variety of longitudinal studies (most notably the population-representative Health and Retirement Study), harmonization projects, archives, repositories, and networks intended to facilitate research on aging in the behavioral and social sciences. Our data resources include large samples of minority populations to support disparities research as well as educational cohorts to study life course aging and cognition. Further, NIA support for international comparators to the U.S. Health and Retirement Study include implementation of the Harmonized Cognitive Assessment Protocol to facilitate cross-national research on dementia epidemiology and produce national estimates of AD prevalence and incidence. Data from these studies are available to qualified researchers, subject only to restrictions imposed for some linked administrative data. With input from periodic reports, including those by the NACA, the National Academies of Sciences, Engineering, and Medicine, and ad hoc expert review panels, BSR has developed a portfolio of publicly available data projects to meet evolving scientific priorities, many of which are highlighted on the NIA website.

Division of Geriatrics and Clinical Gerontology (DGCG)

The DGCG supports research on health and disease in older people and research on aging over the human lifespan, including its relationships to health outcomes. DGCG comprises three major research areas, divided into three division branches — Geriatrics, Clinical Gerontology, and Clinical Trials. Program-wide emphases include research training and career development to attract new investigators to the field of aging and to further the development of active investigators in clinical medicine and biomedical research, and the application of new technologies to expand opportunities for clinical aging research.

Geriatrics focuses on health issues regarding older people. Research emphases include multifactorial geriatric syndromes such as falls, frailty, and various types of disability; effects of comorbidity and polypharmacy; effects of age-related changes on clinical or functional disease outcomes or treatment responses; effects of physical activity on disease and disability in older persons; and the elucidation, diagnosis, and treatment of previously unappreciated pathologic changes in old age (e.g., sarcopenia, vascular stiffening, diastolic dysfunction). The Geriatrics Branch supports the Claude D. Pepper Older Americans Independence Centers (OAICs). The OAICs conduct basic and clinical research to enhance the ability of older people to maintain their independence.

Clinical Gerontology focuses on clinically related research on aging changes over the lifespan. Research emphases include healthy aging across the lifespan (including exceptional longevity); protective factors against multiple age-related conditions; determinants of rates of progression of age-related changes that affect disease risk, particularly those for multiple age-related conditions; menopause and mid-life aging changes; translational human research to follow up findings from basic research on aging; long-term effects of current or new interventions that may be administered over a large part of the lifespan; and long-term effects of physical activity throughout the lifespan.

Clinical Trials plans and administers clinical trials on age-related issues. Research emphases include interventions to prevent or treat “geriatric syndromes,” disability, and complications of comorbidity or polypharmacy; trials to detect age- or comorbidity-related differences in responses to interventions against conditions found in middle age and old age; interventions for problems associated with menopause and other mid- and late-life changes; interventions that may affect rates of progression of age-related declines in function in early and mid-life; and interventions with protective effects against multiple age-related conditions, including intervention studies on the effects of androgens in older men.

Division of Neuroscience (DN)

Organized into five branches, DN fosters and supports extramural and collaborative research and training to advance understanding of neural and behavioral processes and of neurodegenerative diseases associated with brain aging. Research on dementias of old age — in particular Alzheimer's disease — is one of the division's highest priorities.

Neurobiology of Aging and Neurodegeneration

This branch fosters research aimed at understanding how the nervous system is affected during normal and pathological aging. Research is supported on the genetic, molecular, cellular, and neural mechanisms underlying changes in the brain and its interaction with other physiological systems.

Fundamental Neuroscience supports studies on age-related structural and functional changes in the brain, including mechanisms of selective vulnerability and plasticity of neural cells, synapses, circuits, and networks to neurodegeneration. Research is supported on the role of hallmarks of aging, senescence, genetics/epigenetics, DNA damage, cell stress, proteostasis, mitochondria, metabolism, lipid neurobiology, neuroglia, neuroplasticity, neural stem cells/neurogenesis, and cell reprogramming in brain aging and neurodegeneration. Basic Science of Alzheimer’s Disease supports examination of molecular, cellular, synaptic, and circuitry mechanisms, inflammation, proteinopathy, protein polymorphisms, structural biology, and cerebrovasculature in the etiology and pathobiology of Alzheimer’s disease and other dementias of aging. In Integrative Neurobiology, the focus is on neural mechanisms underlying age-related changes between organ systems and the CNS, on endocrine and immune functions, and on neurodegenerative diseases associated with infectious agents. Sleep and Biological Rhythms encompasses age-related studies of epidemiology, etiology, pathogenesis, diagnosis, treatment, and prevention of sleep disorders of older people; and of altered sleep-wake cycles/disordered biorhythmicity and their behavioral and neurodegenerative effects in aging.

Behavioral and Systems Neuroscience

This branch emphasizes research on the neural mechanisms underlying age- and Alzheimer’s disease-related changes in cognition, emotion, sensory, and motor function, from the level of genes to the whole organism and epidemiological studies of populations. Studies of molecular, structural and dynamic brain changes, including research on adaptation or plasticity, resilience, and reserve are of particular interest, as well as interventions to maintain or gain function in older age. The Sensory Processes program supports studies on neural mechanisms of age- and/or disease-related alterations in visual, auditory, somatosensory, vestibular, and chemosensory functions. Research on disorders of the sensory systems, such as presbycusis or pain, are highlighted. To understand Motor Function, research is supported on proprioception, postural control and balance, neuromuscular function, sensory-motor integration, and movement disorders in aging, including Parkinson's disease. The relationship between sensory or motor dysfunction and age-related dementia is a developing area. Cognitive and Affective Neuroscience encompasses research on neural mechanisms of age-related change in cognitive processes, including learning, memory, attention, executive function, and language as well as the neurobiology of age-related changes in emotion. Prevention and treatment trials for age-related cognitive decline also are emphasized. Investigations of the neural underpinnings of delirium and post-operative cognitive decline are supported, including clinical trials for prevention and remediation. The relationship between delirium and dementia, as well as the distinction between age-related cognitive decline and pre-symptomatic Alzheimer’s disease, are also of interest. DN, and this branch in particular, interact and collaborate with the NIA Division of Behavioral and Social Research, where psychological science and behavioral neuroscience converge, as well as with the NIA Division of Geriatrics and Clinical Gerontology, where aging of non-neural systems, geriatric syndromes, and central nervous system function converge.

Population Studies and Genetics

This branch fosters research aimed at understanding the contributions of population and genetics studies in brain aging and neurodegeneration. The Population Studies portfolio embraces research that examines the trajectory of cognitive decline, mild cognitive impairment (MCI), and Alzheimer's disease and related dementias (AD/ADRD). This may include direct measurements of morbidity levels in general populations and race/ethnic subpopulations; identification of potential risk and protective factors through longitudinal studies using biospecimens (blood, cerebrospinal fluid, CNS tissues); neuroimaging; and medical history data to better understand the etiology of MCI/AD/ADRD. The Genetics of Alzheimer's disease portfolio is aimed at discovery of therapeutic targets for AD by identification of regions in the genome conferring risk or protection and associated molecular pathways with clear link to the etiology of disease. Research focuses on discovery of novel genomic elements and their functional roles driving heterogeneity and pathogenesis of AD. Studies include assessment of genetic contribution/impact on disease progression and why some individuals who have risk factors escape AD. A major effort to harmonize phenotypic data across cohorts that are in the genetics portfolio is underway. The portfolio includes genome analysis by machine learning and functional genomics to delineate causal genetic variants and related biological mechanisms.

Translational Research

This branch supports the full spectrum of drug discovery and preclinical drug development from target discovery and validation through securing Investigational New Drug status for small molecules and biologics aimed at prevention, treatment, and management of individuals with or at-risk for cognitive decline and AD/ADRD. In addition to building a portfolio of novel therapeutics for a diverse set of therapeutic targets, the branch supports the development of translational infrastructure that operates under open-source, open-science principles to increase research rigor, reproducibility, and translatability. Central to the mission of the branch is providing support for integration of data science disciplines (such as systems and network biology, systems pharmacology, and translational bioinformatics) with experimental approaches throughout the translational process, including for the purposes of advancing drug repositioning and combination therapy development.

Clinical Interventions and Diagnostics

This branch supports research on the diagnosis, prevention, treatment, and management of individuals with or at-risk for cognitive decline and AD/ADRD. The branch supports all stages of clinical development for pharmacologic and non-pharmacologic interventions and combination therapies, as well as research on methods development and training for innovative trial design. The branch also supports research on diagnostics aimed at the development and evaluation of reliable and valid multidimensional diagnostic procedures and instruments including imaging, fluid and digital biomarkers, and clinical and neuropsychological instruments for diagnosis, progression, and response to treatment. A central goal is the maintenance and development of research infrastructure for clinical trials and biomarkers development, which includes the national network of Alzheimer’s Disease Research Centers.
