  • Low rates of Alzheimer's disease found in Cherokee Indians
    October 14, 1996

    The degree to which Cherokee Indians are of pure ancestry or mixed ancestry may play a role in delaying the development of Alzheimer's disease after age 65. Research by National Institute on Aging (NIA) grantees at the University of Texas...

  • Scientists develop mouse model for Alzheimer's disease
    October 3, 1996

    A new mouse model that will further understanding of Alzheimer's disease and ultimately allow for testing of drug therapies has been developed by scientists at the University of Minnesota. The genetically-engineered mouse is the first to exhibit...

  • Study yields new clues for Alzheimer's disease
    September 24, 1996

    Several recent studies have begun to define the involvement of certain genes in the development of Alzheimer's disease. But a new study comparing the occurrence of dementia and Alzheimer's disease among different populations suggests there...

  • Estrogen and delayed onset of Alzheimer's disease
    August 16, 1996

    National Institute on Aging (NIA)-supported scientists at Columbia-Presbyterian Medical Center suggest that estrogen therapy taken by post-menopausal women may significantly delay the onset of Alzheimer's disease. Results of the study appear in...

  • A gene involved in regulating longevity in worms may provide a clue to human aging
    August 8, 1996

    Discovery of a mutant gene involved in the regulation of longevity of a primitive worm, C. elegans, may provide a clue as to how humans age. Normal development and longevity in the worm C. elegans are regulated by the age-1 gene. Lack of age-1...

  • Exercise can boost cardiac fitness in conditioned and out-of-shape older people
    August 2, 1996

    It may not be too late to benefit from exercise, even for people in their 60's and older, according to scientists at the National Institute on Aging (NIA) Gerontology Research Center, the Johns Hopkins Medical Institutions, and the Veterans...

  • Tai chi for older people reduces falls, may help maintain strength
    May 2, 1996

    Tai Chi, a martial arts form that enhances balance and body awareness through slow, graceful, and precise body movements, can significantly cut the risk of falls among older people and may be beneficial in maintaining gains made by people age 70 and...

  • New findings suggest how caloric restriction may prolong healthy life
    April 29, 1996

    Researchers at the National Institute on Aging's (NIA) Gerontology Research Center (GRC) have shown for the first time that reducing calorie intake by 30 percent lowers body temperature in monkeys. This lowered body temperature is a result of a...

  • AIDS virus reformatted to shuttle repair genes to diseased brains
    April 11, 1996

    Scientists supported by the National Institutes of Health (NIH) have developed a benign, reconstituted form of HIV, the virus known to cause AIDS, and used it to shuttle repair genes to diseased neurons in rat brains. By removing any trace of the...

  • Premature aging gene identified
    April 11, 1996

    Werner's syndrome (WS), a rare familial disease with symptoms resembling premature aging, is considered a partial model of human aging. People with WS develop a vast array of age-related diseases including arteriosclerosis, cancer, diabetes, and...
