Well I went ahead and made the appointment for the tests so hopefully in a week and half will know something.

There is one thing that me and my siblings have noticed lately and I was hoping someone might have more knowledge about this. I was spending the day with her the other day and there were no issues at all with her memory during the day. Then later in the evening she complained about having an headache and feeling light-headed. It was then shortly after that she started calling me by another name and didn't recognize who I was. My siblings have also noticed that everything can be fine and then all of a sudden she doesn't recognize them or thinks they are someone else and most of the time while that is happening she says she has a headache or feels light-headed.

So does anyone have any experience with something like this and does this sound like a symptom of B12 deficiency?
