About this program

The National Institute on Aging (NIA), a component of the Department of Health and Human Services National Institutes of Health, funds biomedical, social, and behavioral research on aging processes, diseases of aging, and age-related special problems, with the most recent grant award dated March 3, 2027, under CFDA 93.866.

The program funds concrete research activities including mechanisms of Alzheimer's disease and related dementias, Parkinson's disease pathogenesis, age-related bone and musculoskeletal deterioration, caregiver health in dementia, neural mechanisms of cognitive aging, brain imaging biomarkers, cellular senescence, and health services research on aging populations. Recent awards span investigator-initiated postdoctoral and predoctoral fellowships examining topics from social isolation's effects on Alzheimer's pathology to metabolic drivers of neurodegeneration, as well as clinical epidemiology projects analyzing access to novel Alzheimer's therapies and Medicare Advantage plan impacts on surgical care for older adults.

Award distribution is heavily dominated by the National Institute on Aging itself, which accounted for 15,389 of 32,055 total awards ($59.15 billion of $68.11 billion in combined federal obligated dollars), with smaller contributions from the broader NIH ($7.62 billion across 15,903 awards) and the NIH National Institute of Neurological Disorders and Stroke ($261.6 million across 50 awards). Project Grants comprise 95 percent of the portfolio (30,563 awards), with Block Grants at 3 percent and Cooperative Agreements at 2 percent. Award cadence has ranged from 1,479 annually in 2023 to 78 in the first months of 2027. The program has supported grants continuously since 1977 and demonstrates sustained recent activity.

Representative recent postdoctoral and predoctoral fellowships awarded in late February and early March 2027 included studies of social isolation and cerebral blood flow in Alzheimer's models ($44,306), emotion regulation in dementia caregivers ($80,800), mitochondrial mass homeostasis in aging ($76,780), access to amyloid-targeting therapies ($50,114), and gait deficits in Parkinson's disease with REM sleep behavior disorder ($78,928). Combined federal and non-federal obligations totaled $71.85 billion against the $68.11 billion federal share, indicating modest cost-sharing by recipients.

Several forecasted grant opportunities remain in preparation. The Alzheimer's Drug-Development Program (RFA-AG-28-009, Cooperative Agreement) will support preclinical and Phase I clinical development of novel therapeutics targeting Alzheimer's prevention or progression. The Claude D. Pepper Older Americans Independence Centers (RFA-AG-28-001, Grant/P30) will fund centers of excellence in geriatrics research with integrated cores. The NIA Genetics of Alzheimer's Disease Data Storage Site (RFA-AG-27-005, Cooperative Agreement) will operate a cloud-based platform for secure, scalable access to large-scale genetic and genomic data. These forecasts indicate active pipeline development but applications are not currently being solicited—prospective applicants should contact NIA staff to discuss fit with programmatic priorities.

Eligibility

Applicant eligibility

Grants: Universities, colleges, medical, dental and nursing schools, schools of public health, laboratories, hospitals, State and local health departments, other public or private institutions (both for-profit and nonprofit), and individuals. National Research Service Award: Individual NRSAs may be made for postdoctoral training to applicants who hold a professional or scientific degree (M.D., Ph.D., D.D.S., D.O., D.V.M., Sc.D., D.Eng., or equivalent domestic or foreign degree) or for predoctoral training to applicants registered for doctoral research training. Institutional NRSAs may be made for both predoctoral and postdoctoral research training. Predoctoral awardees must have a baccalaureate degree. Applicants must be citizens of the United States or admitted for permanent residency. Individual NRSA awardees must be nominated and sponsored by a public or private nonprofit institution having staff and facilities suitable to the proposed research training. Nonprofit domestic organizations may apply for the Institutional NRSA. SBIR grants can be awarded only to domestic small businesses (entities that are independently owned and operated for profit, are not dominant in the field in which research is proposed, and have no more than 500 employees). Primary employment (more than one-half time) of the principal investigator must be with the small business at the time of award and during the conduct of the proposed project. In both Phase I and Phase II, the research must be performed in the U.S. or its possessions. STTR grants can be awarded only to domestic small business concerns (entities that are independently owned and operated for profit, are not dominant in the field in which research is proposed and have no more than 500 employees) which "partner" with a research institution in cooperative research and development. At least 40 percent of the project is to be performed by the small business concern and at least 30 percent by the research institution. In both Phase I and Phase II, the research must be performed in the U.S. and its possessions. To be eligible for funding, a grant application other than a fellowship must be assessed for scientific merit by a scientific review group and receive approval from a national advisory council. Individual funding opportunity announcements published in the NIH Guide provide more detail on eligibility.

Beneficiary eligibility

Any nonprofit or for-profit organization, company, or institution engaged in biomedical research. Students pursuing doctoral research training.

Uses of assistance

Research grants are intended to support the direct costs of a project in accordance with an approved budget, plus an appropriate amount for facilities and administrative costs. Grantees must agree to administer the grant in accordance with the regulations and policies governing the research grants program of the Public Health Service. National Research Service Awards (NRSA) (Individual) are made directly to approved applicants for research training in specified biomedical shortage areas. In addition, National Research Service Awards (Institutional) may be made to institutions to enable them to make NRSAs to individuals selected by them. Each individual who receives a postdoctoral NRSA is obligated, upon termination of the award, to comply with certain service and payback provisions. Regulations are published in the Code of Federal Regulations and 42 CFR, Part 66. SBIR Phase I grants (of approximately 6 months' duration) are to establish the technical merit and feasibility of a proposed research effort that may lead to a commercial product or process. SBIR Phase II grants are for the continuation of the research initiated in Phase I and that are likely to result in commercial products or processes. Only Phase I awardees are eligible to apply for Phase II support. STTR Phase I grants (normally of 1- year duration) are to determine the scientific, technical, and commercial merit and feasibility of the proposed cooperative effort that has potential for commercial application. Phase II funding is based on results of research initiated in Phase I and scientific and technical merit and commercial potential on Phase II application.

Length and time phasing of assistance

Grant Awards are usually made annually and usually with project periods not to exceed 5 years in length. National Research Service Awards: Institutional awards may be made for up to 5 years, and individual awards may be made for as many as 3 years. SBIR: Normally, Phase I awards are for 6 months; normally, Phase II awards are for 2 years. STTR: Normally, Phase I awards are for 1 year; normally, Phase II awards are for 2 years.

Phase II grant applications will be reviewed based upon the following criteria: (1) The degree to which the Phase I objectives were met and feasibility demonstrated; (2) the scientific and technical merit of the proposed approach for achieving the Phase II objectives; (3) the qualifications of the proposed principal investigator, supporting staff, and consultants; (4) the technological innovation, originality, or societal importance of the proposed research; (5) the potential of the proposed research for commercial application; (6) the reasonableness of the budget requested for the work proposed; (7) the adequacy and suitability of the facilities and research environment; and (8) where applicable, the adequacy of assurances detailing the proposed means for (a) safeguarding human or animal subjects, and/or (b) protecting against or minimizing any adverse effect on the environment.

Award procedure

Grants and Institutional NRSAs: Each application receives an initial scientific review by non-NIH scientists and a secondary review by the National Advisory Council on Aging. Individual NRSAs do not receive a secondary review by the National Advisory Council on Aging. Awards are issued by the NIA to the grantee institution. All accepted SBIR/STTR applications are evaluated for scientific and technical merit by an appropriate scientific peer review panel and by a national advisory council or board. All applications receiving a priority score compete for available SBIR/STTR set-aside funds on the basis of scientific and technical merit and commercial potential of the proposed research, program relevance, and program balance among the areas of research.

Time to approval or disapproval

Grants: From 6 to 9 months. National Research Service Awards: From 6 to 9 months. SBIR/STTR: About 7-1/2 months.

Renewals

Grants: Renewal applications are accepted for most programs. Most individual NIH postdoctoral fellowship support is for no more than 3 years. Most individual predoctoral support is for no more than five years. Exploratory/developmental grant awards and Small Grant awards may not be renewed.

Appeals

A principal investigator may question the substantive or procedural aspects of the review of his/her application by communicating with the staff of the Institute. A formal appeal requires the signature of the appropriate institutional official.
