THE AMAZING AGING MIND
Getting old with a sense of humor.......(great website for those caregivers out there)
""People with dementia do tend to revert to past memories, but not necessarily childhood memories. ""
""Some people will be stuck at age 30 one day, then they'll be in their teens the next, then childhood for a minute or two each day. ""
""It just goes all over the place except the present. As memory becomes less "sticky" with age, new memories are more difficult to make. Thus old memories that are already formed are the ones that are recalled easiest."
