What is AD/ADRD?

Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD) refers to the most common forms of dementia. Dementia likely affects more than 6 million people in the U.S. and more than 55 million people worldwide. At this time, there are no known treatments to prevent or stop the progression of dementia. The toll on individuals, caregivers and society is enormous and will increase as the population ages unless effective interventions are developed. NINDS collaborates with NIH’s National Institute on Aging (NIA), the lead NIH Institute for Alzheimer’s disease (AD) research, to establish research priorities and fund biomedical research in AD as well as several Alzheimer’s disease-related dementias (ADRDs).

While AD is the most common dementia diagnosis, ADRDs share many cognitive and pathological features with and can be difficult to distinguish from AD. In fact, more often than not, patients with a clinical diagnosis of Alzheimer’s disease frequently have different mixtures of brain pathologies, complicating both the diagnosis, as well as the treatment.

The ADRDs include:

Going forward, NINDS and NIA will continue to partner in AD/ADRD research planning and implementation, and we urge the research community to join in our efforts to accelerate scientific progress toward reducing the enormous burden and cost of dementia.

Please note that an approved concept listed below does not necessarily indicate an award mechanism or funding allocation is imminent or will happen. The funding opportunity is only official when published in the NIH Guide.


Early-Stage Therapy Development for ADRD - This initiative will encourage early-stage development of novel small molecule or biologic therapeutics for ADRD. This initiative will support research to enable competitive follow-on applications that meet the entry criteria for the Blueprint Neurotherapeutics Network, Blueprint Biologics, or other similar later-stage translational programs. Contact PO: Rebecca Roof

Genome Editing for ADRD - This initiative will support early translational research focused on somatic cell genome editing for Alzheimer's Disease Related Dementias (ADRDs). It is expected that these studies will address the feasibility of using genome editing for therapy development for ADRDs. Contact PO: Timothy LaVaute

Blood Brain Barrier Response to Antibodies Targeting Beta-Amyloid - This initiative is designed to promote discovery of cellular and molecular mechanisms that underlie brain blood vessels responses to passive anti-beta-amyloid immunotherapy that result in amyloid-related imaging abnormalities. The goal is to establish an understanding of molecular mechanisms that can be targeted to protect the BBB, and thus the brain blood vessels, during therapeutic interventions that target beta-amyloid. Contact PO: Roderick Corriveau

Neuropathological Assessment of TBI-related Neurodegeneration and Neurocognitive Decline - This initiative will support applications for a multisite study to comprehensively characterize the neuropathological features associated with neurodegeneration and neurocognitive decline in persons with a history of traumatic brain injury (TBI). To further advance research in the area, broad sharing of clinical and neuropathological data will be a critical feature of this initiative including developing a digital resource for distribution and sharing of assessed neuropathological tissue. Contact PO: Nsini Umoh

PET ligand development for the ADRDs - The purpose of this initiative is to support a multi-center program that will apply innovative and interdisciplinary approaches to identify and validate PET radioligands for ADRD-related targets (e.g., tau, FUS, TDP43, alpha-synuclein, etc.) and pathways (e.g., neuroinflammation, autophagy, mitochondria, etc.).  Collaborations with investigators overseeing brain bank resources and/or those overseeing existing ADRD-related resources and clinical infrastructure are encouraged. Contact PO: Debra Babcock

Contact PO: Linda McGavern

Investigating Distinct and Overlapping Mechanisms in TDP-43 Proteinopathies, including in LATE, FTD, and other ADRDs - This initiative would support studies establishing deeper mechanistic insight and causal cellular and molecular relationships between TDP-43 pathology and clinical phenotypic outcomes. Additionally, the initiative would require comparisons between Alzheimer’s Disease Related Dementias (ADRD) TDP-43 proteinopathies, such as limbic-predominant age-related TDP-43 encephalopathy (LATE), with or without Alzheimer’s disease neuropathologic change (AD-NC), and frontotemporal lobar degeneration with TDP-43 inclusions (FTLD-TDP) to further understand distinct and overlapping mechanisms in these different syndromes. Contact PO: Linda McGavern

Neuropathological Interactions Between COVID-19 and ADRD - This initiative would solicit applications that propose studies in animal, cell culture, and/or human tissue models to elucidate the mechanisms by which COVID-19 interacts with and/or modulates ADRD-relevant phenotypes. Either the model itself or the experimental readouts will be required to incorporate ADRD risk factors, pathologies, or relevant comorbidities. Contact PO: William P. Daley

Development & Characterization of Experimental models of post-TBI ADRD - This initiative is designed to support interdisciplinary teams across multiple sites aimed at developing and characterizing a variety of experimental models that can accurately reproduce the neuropathological signatures and clinically relevant neurodegenerative, biochemical, and behavioral TBI-related dementia sequelae and phenotypes as those seen in humans. Successful models will accelerate the identification of factors and mechanistic pathways contributing towards the predisposition, initiation of and development of neurodegenerative dementia post-TBI. Innovative applications reaching beyond the current AD/ADRD animal models are highly encouraged. Contact PO: Hibah O. Awwad

Development and Validation of Models for ADRD - This initiative would support development and validation of clinically relevant models of Alzheimer’s Disease Related Dementias (ADRD). Cellular and animal models of multiple interacting pathologies, that mimic the multiple interacting risk factors and comorbidities seen in patients, and that advance key molecular pathways in a pathophysiologically relevant context will be supported. New models need to be innovative and address a gap in the currently available models. Contact POs: Linda McGavern and Rebecca Roof

Anti-amyloid efficacy in populations with vascular risk factors of cognitive impairment and dementia - The goal of this initiative is to encourage the development and implementation of a phase 3 clinical trial to determine the efficacy and safety of FDA approved monoclonal antibody therapy in mixed-etiology dementia populations with evidence of vascular contributions to cognitive impairment and dementia. Contact PO: Rebecca Hommer


NINDS Institutional AD/ADRD Research Training Program PAR-22-021. The goal of this initiative is to provide support for institutional research training programs in ADRD. A fundamental goal of this specific program will be for trainees to develop an understanding not only differences and similarities among the various AD/ADRD disorders, but more generally to develop a strong scientific and innovative orientation towards understanding the root mechanistic causes of cognitive impairment and dementia. Contact PO: Stephen Korn
