Welcome to the home page of the Garrison Institute on Aging (GIA) of Texas Tech University Health Sciences Center (TTUHSC). The GIA’s mission is to ‘promote healthy aging through cutting-edge research in Alzheimer's disease and other diseases of aging, and through innovative educational and community outreach programs that target students, clinicians, researchers, health care professionals and the public. The GIA’s ultimate goal is to become nationally and internationally recognized as a center of excellence for the creation and application of new knowledge about healthy aging through research, innovative interdisciplinary education, and collaborative outreach efforts with the community.

The GIA has several programs and resources available such as: 

  • programs to provide caregivers with information on the latest research in Alzheimer’s therapeutics
  • programs to train retired seniors who wish to work as volunteers in Alzheimer’s care facilities and with family members of persons with Alzheimer’s
  • and programs designed to help persons exercise in ways to promote physical and mental fitness
  • Garrison Brain Bank offers tissue for scientific studies

Through these innovative programs and resources, we aim to promote healthy aging, particularly in individuals older than 50 years of age, and we also aim to help them lead a healthier lifestyle.

The Garrison Brain Bank program was established in 2007.  The mission of GIA Brain Bank is to provide free brain autopsies to healthy individuals with no dementia and to the families of patients with neurodegenerative diseases, including Alzheimer’s dementia and dementia associated with other types of neurodegenerative diseases.  This program provides brain specimens to scientists who are:

  • investigating the causes of dementia
  • studying early cellular changes and subsequent cellular changes during neurodegenerative disease progression
  • developing biomarkers at different stages of neurodegenerative disease progression
  • and developing therapies for preventing such diseases, slowing their progression, and attempting to mitigate their impact on patients. 

The design and performance of innovative and cutting-edge research is also a major goal of the GIA. We are proud of our GIA scientists, who are funded by competitive NIH grants. Major research objectives of the GIA research include:

  • better understanding molecular and cellular bases of aging, Alzheimer’s dementia, and age-related neurodegenerative diseases
  • developing therapeutics to prevent or to delay the onset of Alzheimer’s disease and other dementias
  • and developing technologies and methods that will assist scientists worldwide, in conducting state-of-the-art basic, applied, and clinical research of age-related neurodegenerative diseases. 

Our staff promotes education in geriatrics to medical students, new physicians, and clinicians. We continue our efforts in interaction and collaboration with graduate students and medical students at the TTUHSC and TTU; with faculty members in the School of Medicine; and with students and professors in the TTUHSC Schools of Health Professions, Nursing, and Pharmacy. We intend for the GIA to become a world-wide leader in researching healthy aging; and in providing professionals with impactful education in geriatric care and Alzheimer’s dementia research

We wish to thank the Garrison Family Foundation; leadership of TTUHSC, particularly President, Tedd Mitchell, M.D.; Executive Vice President and Provost, Steven Berk, M.D. and Senior Vice President for Research, Michael Conn, Ph.D. and all our colleagues and students in the School of Medicine, in the TTUHSC Schools of Health Professions, Nursing and Pharmacy for their kind support of our research efforts.

We thank you very much for visiting the GIA website. Please contact me, if you would like additional information.
