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. Currently, 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 and for NIH's response to the National Plan to Address Alzheimer’s Disease, to establish research priorities and fund biomedical research to decrease the burden of dementia on individuals, families, and communities. 

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 have different mixtures of brain pathologies, complicating both the diagnosis, as well as treatment. A special video testimonial to raise awareness of the disease burden on patients with AD/ADRD and their caregivers titled “Voices of AD/ADRD” was presented at the NINDS ADRD Summit 2022, and can be viewed here:

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.

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 (PAR-23-154) - 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
