The NIA leads a broad scientific effort to understand the nature of aging and to extend the healthy, active years of life.[1] In 1974, under Public Law 93-296, Congress granted authority to form NIA to provide leadership in aging research, training, health information dissemination, and other programs relevant to aging and older people.[2] In January 2011, President Obama signed into law the National Alzheimer’s Project Act, designating the NIA as the primary federal agency on Alzheimer's disease research.[3]
In 2024 NIA is led by Director, Richard J. Hodes, M.D, and Deputy Director Amy S. Kelley, M.D.[4][5]
NIA's mission is to improve the health and well-being of older Americans through research, and specifically to:
Support and conduct high-quality research on:
Aging processes
Age-related diseases
Special problems and needs of the aged
Train and develop highly skilled research scientists from all population groups.
Develop and maintain state-of-the-art resources to accelerate research progress.
Disseminate information and communicate with the public and interested groups on health and research advances and on new directions for research.
Programs
NIA sponsors research on aging through extramural[7] and intramural[8] programs. The extramural program funds research and training at universities, hospitals, medical centers, and other public and private organizations nationwide.
One such example is the Alzheimer’s Disease Research Centers (ADRCs). As of 2022, the NIA funds over 30 centers at medical institutions throughout the United States.[9][10]
The intramural program conducts basic and clinical research in Baltimore, Maryland, and on the NIH campus in Bethesda, Maryland.
Eliezer Masliah was appointed head of the National Institute on Aging's Division of Neuroscience in 2016.[11]
The National Institutes of Health (NIH) is the primary agency of the United States government responsible for biomedical and public health research. It was founded in 1887 and is now part of the United States Department of Health and Human Services. Many NIH facilities are located in Bethesda, Maryland, and other nearby suburbs of the Washington metropolitan area, with other primary facilities in the Research Triangle Park in North Carolina and smaller satellite facilities located around the United States. The NIH conducts its own scientific research through the NIH Intramural Research Program (IRP) and provides major biomedical research funding to non-NIH research facilities through its Extramural Research Program.
The National Institute of Neurological Disorders and Stroke (NINDS) is a part of the U.S. National Institutes of Health (NIH). It conducts and funds research on brain and nervous system disorders and has a budget of just over US$2.03 billion. The mission of NINDS is "to reduce the burden of neurological disease—a burden borne by every age group, every segment of society, and people all over the world". NINDS has established two major branches for research: an extramural branch that funds studies outside the NIH, and an intramural branch that funds research inside the NIH. Most of NINDS' budget goes to fund extramural research. NINDS' basic science research focuses on studies of the fundamental biology of the brain and nervous system, genetics, neurodegeneration, learning and memory, motor control, brain repair, and synapses. NINDS also funds clinical research related to diseases and disorders of the brain and nervous system, e.g. AIDS, Alzheimer's disease, epilepsy, muscular dystrophy, multiple sclerosis, Parkinson's disease, spinal cord injury, stroke, and traumatic brain injury.

It is tasked with allocating about $3.6 billion in FY 2020 in tax revenue to advancing the understanding of the following issues: development and progression of disease, diagnosis of disease, treatment of disease, disease prevention, reduction of health care disparities within the American population, and advancing the effectiveness of the US medical system. NHLBI's Director is Gary H. Gibbons (2012–present).
The National Cancer Institute (NCI) coordinates the United States National Cancer Program and is part of the National Institutes of Health (NIH), which is one of eleven agencies that are part of the U.S. Department of Health and Human Services. The NCI conducts and supports research, training, health information dissemination, and other activities related to the causes, prevention, diagnosis, and treatment of cancer; the supportive care of cancer patients and their families; and cancer survivorship.
The National Institute of Allergy and Infectious Diseases is one of the 27 institutes and centers that make up the National Institutes of Health (NIH), an agency of the United States Department of Health and Human Services (HHS). NIAID's mission is to conduct basic and applied research to better understand, treat, and prevent infectious, immunologic, and allergic diseases.
The Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) is one of the National Institutes of Health (NIH) in the United States Department of Health and Human Services. It supports and conducts research aimed at improving the health of children, adults, families, and communities, including:
The National Institute of Environmental Health Sciences (NIEHS) conducts research into the effects of the environment on human disease, as one of the 27 institutes and centers of the National Institutes of Health (NIH). It is located in the Research Triangle Park in North Carolina, and is the only primary division of the NIH located outside of the Washington metropolitan area.
The National Human Genome Research Institute (NHGRI) is an institute of the National Institutes of Health, located in Bethesda, Maryland.
The National Institute of Biomedical Imaging and Bioengineering (NIBIB), founded at the National Institutes of Health (NIH) in 2000, is located in Bethesda, Maryland. It is one of 27 institutes and centers that are part of NIH, an agency of the U.S. Department of Health and Human Services (HHS).
John Quinn Trojanowski was an American academic research neuroscientist specializing in neurodegeneration. He and his partner, Virginia Man-Yee Lee, MBA, Ph.D., are noted for identifying the roles of three proteins in neurodegenerative diseases: tau in Alzheimer's disease, alpha-synuclein in Parkinson's disease, and TDP-43 in Amyotrophic Lateral Sclerosis (ALS) and frontotemporal degeneration.
Andrew B. Singleton is a British neurogeneticist currently working in the USA. He was born in Guernsey, the Channel Islands in 1972, where he lived until he was 18 years old. His secondary education was conducted at the Guernsey Grammar School. He earned a first class degree in Applied Physiology from Sunderland University and his PhD in neuroscience from the University of Newcastle upon Tyne where he studied the genetics of Alzheimer's disease and other dementias at the Medical Research Council (MRC) Neurochemical Pathology Unit. He moved to the United States in 1999, where he began working at the Mayo Clinic in Jacksonville, Florida studying the genetic basis of Parkinson's disease, ataxia, and dystonia. He moved to the National Institutes of Health in 2001 to head the newly formed Molecular Genetics unit within the Laboratory of Neurogenetics. In 2006 he took over as Chief of the Laboratory of Neurogenetics and became an NIH Distinguished Investigator in the intramural program at the National Institute on Aging (NIA) in 2017. In 2020 he stepped down as the Chief of the Laboratory of Neurogenetics and became the Acting Director of the newly formed Center for Alzheimer's and Related Dementias at the NIA. In 2021 he became the Director of CARD.
The NIH Intramural Research Program (IRP) is the internal research program of the National Institutes of Health (NIH), known for its synergistic approach to biomedical science. With 1,200 Principal Investigators and over 4,000 Postdoctoral Fellows conducting basic, translational, and clinical research, the NIH Intramural Research Program is the largest biomedical research institution on earth. The unique funding environment of the IRP facilitates opportunities to conduct both long-term and high-impact science that would otherwise be difficult to undertake. With rigorous external reviews ensuring that only the most outstanding research secures funding, the IRP is responsible for many scientific accomplishments, including the discovery of fluoride to prevent tooth decay, the use of lithium to manage bipolar disorder, and the creation of vaccines against hepatitis, Hemophilus influenzae (Hib), and human papillomavirus (HPV). In addition, the IRP has also produced or trained 21 Nobel Prize-winning scientists.
