My mother has been having problems with her memory over the last couple of years, it's been very gradual. In the beginning, it was so slight, it was hardly noticable but last July, when she was visiting, she would ask me several times what we were doing that day or who we were having lunch with. If I repeated it enough, it would stick. I was very concerned but she absolutely refused to go to the doctor. I cannot remember the last time she went to the doctor.
My brother called me last Thursday. Mom had called him very upset and told him something had gone wrong in her head. A friend of hers finally convinced her she needed to see a doctor, so it's been a round of doctor visits over the past few days. My brother thinks she had a stroke of some kind because the type of memory problem changed drastically over night. She now cannot remember something you just told her at all. I looked at the Alzheimer's site and based on what he told me, it sounds as though she may have vascular dementia. Of course, I am not a doctor, even the doctors need to see her a couple of more times and we won't have any kind of results until next week. And I am just basing that on the few things my brother said.
Something's wrong. And we're waiting to find out just what that is.
