My mother is 86 and based upon all my reading about Alzheimer's, which ive done a lot of lately, I'm sure she has Alzheimer's. Her primary care has seen her twice in the last year and shea due to see him again in March. I faxed him a letter describing the short term memory issues before the first appt and he has given her verbal memory tests at both appts and put her on aricept at the last appt. A diagnosis has not bewn given...but i see further symptoms as the month a go by, lack of ability to follow instructions or conversations, balance checkbook, etc. My question is, should i press for a diagnosis to confirm alzheimers? Is there a reason to have a diagnosis, other than to know what to expect...which i already do thanks to the articles and books ive been reading about the disease.
