My mom is 74 years-old and has Alzheimer's. Two weeks ago she just sat and didn't cary much conversation. We had to get the doctor to change her medications to dissolvable ones. It seems like when she started to take this new medication, she changed. She is now wetting herself and does not know it. She just sits and talks away regardless if anyone is listening ot her. Could this be the next stage or the new medication?
