What to look out for

Memory often changes as people grow older. But memory loss that disrupts daily life is not a typical part of aging.

  • Some people notice changes in themselves before anyone else does.
  • For other people, friends and family may see changes first.

If you notice changes in yourself or a loved one, it is important to see a doctor. Early diagnosis gives people a chance to identify the cause of these changes, which could be reversable in some cases. If it is Alzheimer's disease or another kind of dementia, you can start treatment early, when it is most effective in slowing down the disease.
