Genes

  • Alzheimer's Disease Fact Sheet
    Alzheimer’s disease is an irreversible, progressive brain disease that slowly destroys memory and thinking skills, and eventually even the ability to carry out the simplest tasks. In most people with Alzheimer’s, symptoms first appear after age 60. Estimates vary, but experts suggest that as many as 5.1 million Americans may have Alzheimer’s disease.
  • Alzheimer's Disease Genetics Fact Sheet
    Scientists don't yet fully understand what causes Alzheimer's disease. However, the more they learn about this devastating disease, the more they realize that genes play an important role in its development. Research conducted and funded by the National Institute on Aging (NIA) at the National Institutes of Health and others is advancing the field of Alzheimer's disease genetics.
  • Biology of Aging
    What is aging? Can we live long and well—are they the same? Is aging in our genes? How does our metabolism relate to aging? Can your immune system still defend you as you age? Learn the answer to these questions and more. Biology of Aging: Research Today for a Healthier Tomorrow describes some of NIA’s exciting findings about the basic biology of aging and points to directions for future investigation.
