Mom, has dementia. We notice some changes. Though; yesterday, she looked at a family member's photo (lives long distance) And; asked If, it was a family friend's name. I got really worried. Then, within the same hr. Many more forgetful names & who's santa etc. Thank goodness she was much better within 2 hrs. Is this the downhill slope we read about? Will it come up again with names & photo's etc.?
