Alzheimer's disease (AD) is a devastating illness in elderly individuals, that currently has no known cure. Causal genetic factors only account for 1-2% of AD patients. However, other causal factors are still unknown for a majority of AD patients. Currently, multiple factors are implicated in late-onset AD, including unhealthy diet, physical inactivity, traumatic brain injury, chronic conditions, epigenetic factors, and environmental exposures. Although clinical symptoms of dementia are common to all races and ethnic groups, conditions that lead to dementia are different in terms of lifestyle, genetic profile, and socio-economic conditions. Increasing evidence also suggests that some elderly individuals age without cognitive impairments in their 60-90s as seen in rural West Texas, while some individuals progress with chronic conditions and cognitive impairments into their 60s. To understand these discriminations, we assessed current literature on demographic features of health in rural West Texas. This paper also outlines our initiated clinical study with a purpose of understanding the factors that allow some individuals to live without cognitive impairments at the age of 60-90 years, whereas others develop deficits in cognitive function around or above 60 years. Our ongoing study hopes to determine the factors that delay aging in some individuals by investigating various aspects including genetics, epigenetics, ethnicity, biology, culture, and lifestyle. This will be achieved by gathering information about participants' ethnographic profiles, cognitive assessments, blood-profiles, brain scans, and blood-based genomic analyses in relation to lifestyle. The outcomes of our study will provide insights into healthy aging in rural West Texas. [ABSTRACT FROM AUTHOR]

The Garrison Institute on Aging (GIA) is an established institute within Texas Tech University Health Sciences Center, whose mission is to promote healthy aging through cutting-edge research on Alzheimer's disease (AD) and other diseases of aging through innovative educational opportunities for students, clinicians, researchers, health care professionals, and the public. The GIA has multiple programs, including both research and education on healthy aging and AD, community outreach, caregiving, the Retired Senior Volunteer Program, Healthy Lubbock, the GIA Brain Bank, healthy aging seminars, research seminars, and collaborations and scholarships. The GIA programs connect basic and clinical researchers and health care professionals, and provide a unique environment to help our growing elderly population and patients with AD and their families.
