  • Researchers at the University of Wisconsin-Madison Waisman Laboratory for Brain
    Alzheimer's Disease Neuroimaging Initiative generates promising early findings
    October 1, 2009

    Scientists know that Alzheimer’s disease begins to take root decades before its initial symptoms appear. One of the great challenges for researchers is to pinpoint the earliest signs of Alzheimer’s before it can start to...

  • Dr. Marie Bernard
    A Conversation With... Dr. Marie Bernard
    May 15, 2009

    On Oct. 12, 2008, Dr. Marie Bernard joined the NIA as Deputy Director. She previously held the Donald W. Reynolds Chair in Geriatric Medicine and served as professor and chair of the Donald W. Reynolds Department of Geriatric Medicine...

  • SIRT1 repairs DNA but leads to age-related gene expression in mice
    May 12, 2009

    Scientists have found a mechanism involving the protein SIRT1 that links DNA damage with age-related changes in gene expression. The study in mice has striking parallels with findings from studies of a similar mechanism in yeast. Past...

  • Study shows metabolic adaptation in calorie restriction
    May 12, 2009

    Researchers at the Pennington Biomedical Research Center in Baton Rouge, LA, have shown that when people significantly reduce their calorie intake, they undergo a metabolic adaptation that results in a slower metabolic rate. The slower...

  • Study shows possible link between secondhand smoke, cognitive impairment
    May 12, 2009

    A recent article about a population-based study in England reports that exposure to secondhand smoke could increase the odds of older nonsmokers becoming cognitively impaired. In work funded in part by the NIA, researchers measured levels...

  • Research shows that happiness spreads through social groups
    May 12, 2009

    NIA-funded researchers have found that happiness is not an isolated phenomenon, unique to an individual, but rather spreads through social networks. Using data from the Framingham Heart Study, Drs. Nicholas Christakis of Harvard Medical...

  • Meniscal tears common in older adults, even without symptoms
    May 12, 2009

    The prevalence of meniscal tears in adults increases with age, but often they are not accompanied by knee pain or other symptoms, according to a recent study supported in part by the NIA. Researchers led by Dr. Martin Englund of the Boston...

  • PET scans with PiB show beta-amyloid in brains of cognitively normal older adults
    May 12, 2009

    Two recent NIA-funded studies used novel imaging techniques to explore the possible connection between the buildup of beta-amyloid protein deposits in the brains in living people and the risk of developing Alzheimer’s disease (AD)....

  • Bone remodeling protein works indirectly through gut
    May 12, 2009

    The protein Lrp5, long known to play a critical role in bone remodeling, appears to exert its effects through the gut, not directly through the bone, as previously thought, according to preclinical research published in Cell. The findings...

  • Hormone therapy linked to brain shrinkage
    May 12, 2009

    Two recent imaging studies shed light on how menopausal hormone therapy (MHT) may affect the brains of older women. Previous studies showed that MHT increased the likelihood that older women would have difficulty with thinking skills and...
