i do totally agree with the above poster here, she definitely DOES need a good evaluation by at least her primary doc at this point. while this 'could be" the alcohol, esp combined with any meds that truely just DO impact a persons brain like the anti D meds can do, this could also be a 'something" that actually occured "within' her brain like possible stroke(or TIA,'mini stroke") that just can happen and play out this way, or many other 'possibles' that just are very much brain related too.
just getting a good MRI or CT of her brain would at least rule in or out the possible brain/stroke issue here, or alot other things that can happen or just 'be there' within anyones actual brain that simply decide to 'present' themselves kinda out of the blue too? but this DOES require a definite visit with a doc at this point to really determine her overall mental status with certain types of testing done in a more one on one contact basis with her doc and also a good neuro exam that may reveal issues that only a doc would be able to see in her. also, depending upon the actual type of anti D she is on, there usually IS a warning about actually even mixing ANY alcohol when taking them becasue of the overall impact this simply can actually have on someones brain, in many different ways? you should seriously look up the name of that med and the rxing literature which is very easy to find on the net, or simply speaking with any pharmacist at any pharmacy too, just to find out if the alcohol in her particular case is even 'safe" for her to do?
her particular 'type' of memory loss is simply a very 'profound' form from what you just described above(and in no way at all 'normal aging' or anything like that) that NEEDS to be Dxed for the base/reason of the loss here. and she DOES NEED to be evaluated by her doc, and soon. good luck with this. and please DO keep us posted on just what you actually find out too.
