My mother is 81yo, good health, but gets anger and defensive when I ask questions about where she goes or who she is with... my father died about 6 years ago. Her behavior has changed drastically since then ( over spending, gambling etc) , new friends whom I have never heard of calling constantly. She let's "her friends" influence her financial decisions. This is upsetting fo , she only seems to call me when she needs help , a ride here or there. At this point, my fear is that someone else has POA , but they are not family. Yes, could be dementia, but doesn't have any symptoms . Prior to my father's death, we never went anywhere other than as family unit. I find this quite upsetting, as she treats me like an acquaintance , not her own flesh & blood. Any thoughts about this please ?
