North Texas is the newest federal front line in the fight against Alzheimer’s and dementia.
The National Institute of Health has awarded UT Southwestern a $23 million, five-year grant from the National Institute on Aging to establish the North Texas Alzheimer’s Disease Research Center (ADRC). The designation makes it one of 37 such centers nationwide and the second in Texas, according to an announcement.
The new center, based at UT Southwestern Medical Center, will be a focal point for research that could reset how the disease is detected and treated. Scientists plan to probe how cardiometabolic conditions like high blood pressure accelerate dementia, train AI to hear vocal cues of cognitive decline, and build digital replicas of patients to test therapies.
Texas by the numbers
Texas, which is the nation’s second most populous state, has the third-highest number of Alzheimer’s patients, the second-highest Alzheimer’s-related deaths, and the highest dementia burden score, according to UTSW. The dementia burden score is a measure of the emotional and psychological toll on caregivers.
That reality, paired with UT Southwestern’s long-standing strength in neurology and its Peter O’Donnell Jr. Brain Institute, laid the groundwork for the designation.
Tackling cardiometabolic factors in dementia and more
Each Alzheimer’s Disease Research Center operates with a unique theme. In North Texas, the focus will be on advancing the national agenda by exploring how cardiometabolic factors, especially hypertension, contribute to Alzheimer’s and related dementias. Hypertension affects nearly 120 million Americans, according to UTSW.
The center also plans to use AI voice analysis to discover vocal changes that accompany cognitive decline. Researchers will develop “digital twin” technology to create virtual representations of patients, which will help distinguish between factors associated with normal aging and those linked to dementias, according to Dr. Ihab Hajjar, principal investigator of the new center.
“Being named an ADRC is not only an indication of scientific excellence, but also highlights an intentional commitment to research Alzheimer’s disease and cognitive impairment in our community,” said Hajjar, who is professor of neurology and internal medicine at UT Southwestern, in a statement.
Hajjar said the designation gives North Texas “the chance to make an unprecedented leap in understanding and treating Alzheimer’s disease and related dementias.”

North Texas collaboration in the dementia fight
The designation is designed in collaboration with UT Dallas and UT Arlington.
The North Texas ADRC will not only enable new science but also “enhance scientific and clinical collaborations locally and nationally” while creating education opportunities for researchers, clinicians, and learners, according to UTSW.
Dr. William T. Dauer, director of the Peter O’Donnell Jr. Brain Institute, points to the new designation as proof of what can happen when institutions combine their strengths.
“This designation reflects the power of bringing together outstanding scientists, clinicians, and community partners to tackle one of the most urgent societal challenges,” Dauer said in the announcement. “It will strengthen our ability to link discoveries from O’Donnell Brain Institute laboratories with the needs of patients and families in North Texas and beyond, accelerating progress against Alzheimer’s disease and related dementias.”
Dr. Elan D. Louis, chair and professor of neurology and an investigator in the O’Donnell Brain Institute, noted that the ADRC reflects momentum already underway across his department.
“Our new ADRC reflects a growing emphasis in the Department of Neurology on learning about, understanding, and treating a group of disorders that affect millions of elderly people nationwide,” Louis said.
Feeding a national data engine for dementia research
The research generated by all ADRCs will feed into communal datasets that are made publicly available to spur collaboration and speed discovery. Hajjar said those shared efforts could offer “hope to patients with dementia and their loved ones.”
Dementia research is a core area within UTSW, and the new center builds on a decade of work by the O’Donnell Brain Institute.
UTSW also notes its No. 9 ranking for Neurology & Neurosurgery on U.S. News & World Report’s Best Hospitals list and 12 nationally ranked specialties, the most of any hospital in Texas. To date, its faculty have received six Nobel Prizes and include 24 members of the National Academy of Sciences, 23 members of the National Academy of Medicine, and 13 Howard Hughes Medical Institute Investigators.
Leadership brings specialized expertise
UTSW said the center’s leadership team brings long-standing expertise in neurological research with distinct but complementary focuses. Dr. Dauer holds the Lois C.A. and Darwin E. Smith Distinguished Chair in Neurological Mobility Research. Dr. Hajjar holds the Pogue Family Distinguished University Chair in Alzheimer’s Disease Clinical Research and Care, in Memory of Maurine and David Weigers McMullan. Dr. Louis holds the Linda and Mitch Hart Distinguished Chair in Neurology.
The ADRCs were established in 1984 as congressionally designated NIH Centers of Excellence. The mission includes improving detection, diagnosis, treatment, prevention, and care for patients and families. Each center tailors its theme to local populations and scientific priorities.
The North Texas center joins another Texas ADRC, a collaboration between UT Health San Antonio and The University of Texas Rio Grande Valley designated in 2021, strengthening the state’s role in national dementia research efforts.
