Absolutely!! If he lives near her, then he can get her the help she needs. People that show signs of Alzheimers need around the clock care, they could leave the stove on and burn the house down or go out for a walk and get lost or hurt. But first and foremost, he can get her the medical testing that she needs..to help with the diagnosis...maybe shes just getting older and having a hard time remembering things. My Aunt and I will talk 2 to 3 times a week and I swear, she will tell me the same story a hundred times. She doesn't have Alzheimers (that we know of) but we are also in the process of trying to get a diagnosis. My Aunt does have her chldren that still live with her though. So, get your mother in law some help so that something bad doesn't happen to her. Good luck to you!!
tell the other brother before you get alzheimers and forget who he is!!!
