As a family we are becoming increasingly concerned about our mother (my step mother). Her behavior, response and approach to daily life is becoming more and more erratic, peculiar and at time unpleasant. Some of the things we have noticed include; inability to follow a conversation or commenting on a conversation that finished up to an hour before. Shouting something completely random and irrelevant in the middle of a conversation, dressing eccentrically, becoming stressed at very mundane and ordinary things like making dinner (dinner is always a microwave meal these days ) and although she still vacuums the lounge (the kitchen is filthy and the dust is building up around the house, she will not readily accept help) getting dressed is a major stress and she consults the calendar for everything, she forgets the names of usual people and places and often gets really unnecessarily angry at the slightest thing. She is 68. Alongside the worry for her we are also concerned about the stress that its having on our father. He is 77 and lives in a constant state of anxiety ,trying to keep the peace. She has lost a huge amount of weight but that has been checked by the doctor and he changed her medication but her behavior didn't change. She also had tests at the fall clinic as she fell four times in the space of two weeks but again nothing came of it. She came out of the clinic and said the doctors had said everything was fine. My dad has confronted her but she just walks away and we have also had the same response. Dad feels that if he approaches doctors etc behind her back there would be hell to pay if she found out so its easier to keep the peace. We have all spoken to dad about this but he is confused about how he can get her to the doctors for an assessment. She still drives but only locally, walks the dog but seldom goes out and seems to have lost all interest in venturing outside of the home. There seems to be a distinct lack of affection for the grandchildren and now even her own twin daughters. Sorry to ramble on but does anyone have any suggestions ? Are these behaviors linked to dementia/Alzheimer? ..how can we persuade her to get the help she needs when she doesn't recognize or admit that something is wrong? Also how do we get support for dad? This situation is affecting his health too.
