Discuss n's answer to: What to expect from a person coming out of a state ...

You know  you should mention this to her doctor.  Perhaps medication is the cause.  After talking with the doctor, if I were dealing with this problem, I would be (or try to be) as patient as I could be and simply talk with her and explain (in simple words) what she went through.  She is probably afraid because of losing her memory.  My mother-in-law was going through a similar episode.  She was 98  and we had to show her the kind of patience you show a little child.  We didn't tell her too much.  We answered all her questions simply and she was satisfied and then in a few minutes she would start in again.   These situations take a lot of patience and a great deal of love.  Not all older people are easy to talk with in this way.  I hope, for your sake, your mother is thoughtful and kind to you as you both learn each other again.  God Bless.
