I cannot count how many family members she gets mad at and it has gone on. My mother is 87 and we believe she has alzheimers. Her mother and sister both had it and died with complications. My mother seems to get mad all the time. If anybody leaves, she says she doesn't want to go and she is mad when we get back. She got mad because she thinks my niece got mad at her but that didn't happen. It seems like she is mad about everything.
