Health Disparities Research in Neurological Disorders


The NINDS is committed to reducing the disproportionate burden of neurological disease borne by underserved groups of society, including racial and ethnic minority, rural, and socioeconomically disadvantaged populations, by funding a spectrum of research from basic science through clinical studies and training the next generation of health disparities investigators.

Health disparities populations are in need of effective tailored prevention and treatment approaches. Poorer health outcomes in these populations when compared to the general US population have a dramatic impact on public health and are a significant cost to society. Supporting research to diminish health disparities in neurological disorders is inherent in the NINDS mission to reduce the burden of neurological disease, a burden borne by every segment of society.

Funding opportunities in Health Disparities Research

Applications for health disparities research grants are welcomed and encouraged through all NINDS funding opportunities.  Below are current initiatives designed specifically to support health disparities research projects.

NINDS Health Disparities Research and Activity Highlights

The NINDS recognizes that neurological health disparities exist among several populations and is currently assessing the state of knowledge of health disparities across our portfolio in order to set clear research priorities.

Stroke continues to be a major focus of NINDS health disparities research efforts, as it remains one of the largest and most burdensome disparities in neurological health with substantial opportunity for improving outcomes. NINDS supports research to better understand stroke disparities and to inform development of effective interventions in specific population groups who suffer a disproportionately higher burden of stroke.

    REGARDS (REasons for Geographic And Racial Differences in Stroke) is a large cohort study evaluating the causes of racial and geographic differences in stroke mortality and cognitive decline in the United States. Between 2003 and 2007, the study enrolled 30,239 African-American and white participants aged 45 years or older. Approximately half the participants reside in the Stroke Belt (including North Carolina, South Carolina, Georgia, Alabama, Mississippi, Tennessee, Arkansas, and Louisiana), with the remaining participants residing in the other 40 contiguous States; 42% are African-American. Medical and risk factor history were obtained by telephone interview and physical measurements done at a baseline in-home visit, including blood pressure, anthropometry, electrocardiogram, and collection of blood and urine samples. Participants are followed at 6-month intervals by telephone to assess stroke and other events. (Dr. George Howard, PI)

  • Collapsable minus sign. When the image is clicked on the exposed links that are in bulleted fashion will be hidden. Kaiser Permanente Northern California (KPNC) / University of California San Francisco (UCSF)

    The vision of the Kaiser Permanente Northern California (KPNC) / University of California San Francisco (UCSF) collaboration for a Stroke Prevention/ Intervention Research Program in Health Disparities is the elimination in the United States of stroke disparities based on race, ethnicity, and socioeconomic status. Recognizing that there are multi-faceted reasons for the existence of stroke disparities and that these reasons vary across the populations, the initial focus will be the elimination of disparities in hypertension control between African Americans and Caucasians, with a secondary focus of developing knowledge that will help us understand the basis for the apparent increase of stroke incidence in recent years among young adults, most notably African Americans. The investigators will conduct pragmatic randomized controlled trial in the diverse adult population of KPNC that consists of both a clinical algorithm for rapid and effective blood pressure control, as well as a culturally-tailored dietary intervention aimed at more effective sustained blood pressure control. The results of this trial will be used in KPNC to model the impact of these interventions throughout the United States. The research team will also conduct an observational cohort study with KPNC to identify and quantify disparities in the temporal trends in known risk factors for stroke in young adulthood and identify novel factors that may contribute to stroke risk in young adults, and specifically to disparities in this risk. Finally, this project will include an education program for training in disparities issues related to stroke and for dissemination of the research methods and results.

    The New York University (NYU)/Columbia University’s Center for Stroke Disparities Solutions is a consortium between three academic institutions, a municipal healthcare system and home healthcare organization in New York City. The vision is to reduce stroke disparities with a particular focus on prevention of recurrent stroke among Blacks and Hispanics. Project 1 is a Practice-based Trial of Home BP Telemonitoring (HBPTM, )a comparative effectiveness trial of HBPTM alone versus HBPTM plus telephonic nurse case management on prevention of recurrent stroke. Project 2, Stroke Community Transitions Intervention, will evaluate the effectiveness of a culturally-tailored transition care program delivered by nurse practitioners and community health workers in improving BP control, functional outcomes and quality of life in homebound post-acute stroke patients. Project 3, Tailored Approaches to Stroke Health Education, will evaluate the effectiveness of a novel culturally tailored intervention using storytelling in increasing stroke literacy among adults in Black and Hispanic churches across NYC. These three projects address barriers that occur along the continuum of stroke care from the community to homecare, and primary care settings.

    The Los Angeles Stroke Prevention/ Intervention Research Program in Health Disparities is a multi-partnered, highly collaborative research and education center that spans the Los Angeles basin and aims to generate new knowledge about how to end disparities in stroke occurrence. It includes two randomized trials incorporating community health workers, mobile health technology, and the aging services network in Los Angeles, and embracing its most vulnerable and disadvantaged Hispanic, African-American, and Asian-American populations to generate evidence for sustainable, national models for preventing stroke. A third study will elucidate changes over two decades in novel biological and social risk factors for stroke among minorities using a national dataset. Community-academic research partnerships in stroke disparities will be continually sustained through bi-directional knowledge sharing.

  • Collapsable minus sign. When the image is clicked on the exposed links that are in bulleted fashion will be hidden. University of Miami, Miller School of Medicine

    The Hispanic Stroke Prevention/Intervention Research Program is a specialized collaborative center at the University of Miami, Miller School of Medicine, and involves collaborators in Puerto Rico at the University of Puerto Rico and Hospital HIMA. The mission of the center is to improve the treatment and prevention of stroke among Hispanics. This high-impact, multi-disciplinary research program will initiate the Florida Puerto Rico Stroke Registry and collate data from nearly 140 hospitals that are currently collecting American Heart Association’s Get With the Guidelines-Stroke data, as well as specific new data items. The aims are to help identify disparities in acute stroke care and secondary stroke prevention by race, ethnicity, and region and to educate stakeholders in approaches to improve stroke quality regarding stroke disparities. To effectively coordinate this bold initiative, create synergy among collaborating institutions, and support the public health and scientific aims of the registry, the center also contains an administrative core designed to effectively integrate the principal components of the registry and provide the requisite administrative infrastructure to enhance success; a training core focused on stroke disparities research and educational training for healthcare professionals including clinicians, nurses, and pharmacists in Florida and Puerto Rico; and a data management core to serve as the analytic hub of the center and to provide integration of data analysis and collection.

Findings from clinical trials are applied broadly in clinical practice and inform treatment guidelines that affect the clinical care of the general population.  To ensure that new preventive, diagnostic, and treatment approaches are safe and effective for diverse subgroups represented in the population, the studies must enroll sufficient numbers of minority subjects.  The NINDS helps its grantees adhere to the NIH policy for Inclusion of Women and Minorities in Clinical Research through several activities designed to facilitate investigators' efforts to meet enrollment targets.  In addition to the activities described below, a clinical trials recruitment expert in the NINDS Office of Clinical Research works directly with the grantees and program directors on issues related to recruitment and retention.

  • Clinical Research United in Successful Enrollment (CRUiSE)
    NINDS co-sponsored an NHLBI workshop to address successful recruitment in clinical trials. Three key areas were addressed: 1) public and professional awareness and acceptance of clinical trials; 2) human subject research policies, guidelines, and reimbursement; and 3) clinical trial enrollment experience and practice.  A significant portion of the conference addressed the barriers and solutions to improve the inclusion of minorities in clinical trials.  Seventy-five participants, including invited speakers representing clinical researchers, private advocacy groups, industry, and federal sponsors and regulatory agencies, attended. [http://www.nhlbi.nih.gov/meetings/workshops/cruise.htm]
  • Inclusion Research funded by NINDS
    The NINDS is supporting the Northern Manhattan Initiative for Minority Involvement in Clinical Trials (U24; PI: Bernadette Boden-Albala).  This project will develop and evaluate a toolkit of "Best Practices" for the conduct of successful recruitment of racial and ethnic minorities in neurological clinical trials.

NINDS Health Disparities Research Strategic Planning

The NINDS convened an advisory panel to provide recommendations for ways NINDS can maximize investments in research to mitigate the disproportionate burden of neurological disease borne by underserved population groups. Recommendations in the final report from the Health Disparities Research Strategic Planning Advisory Panel  will help NINDS continue its dedication to developing effective programs to understand and address health disparities in neurological disorders.

NINDS Health Disparities Working Group

The mission of the NINDS Health Disparities Working Group is to promote and coordinate health disparities research at the NINDS. Representatives from every scientific cluster and office across NINDS meet monthly at HDWG meetings to discuss health disparities research activities, brainstorm new ideas and work to ensure that NINDS sets and addresses its priorities in health disparities research.
