My mom is 80 years old and still very sharp and alert. She was a Nurse for 30 years which makes this situation more difficult I think. I believe she has early stage Alzheimer's or Dementia. She has been complaining of missing clothes, clothes being worn and then put back folded but dirty, and torn clothes as well. She has complained of missing items, some have been returned according to her. So I have spent money trying to approach all this logically to no avail. I have had locks changed to pick proof, bump key proof locks. I have purchased a radio frequency scanner for her to scan for electronic bugs she believes are in the house. She has purchased steel door poles to prop in front of the doors at night on top of the new locks.
She still feels someone is getting into the house. Today our relationship took a turn for the worse because I contacted her doctor's office to try to get them to call her in for a "routine" checkup but secretly check for Alzheimer's. That failed miserably because the doctors office called and basically spilled the beans and she figured it out. So I got both barrels for going behind her back. She is deeply hurt now and feels alone that no one believes her. I dont know what else to do. This paranoia has been going on for years. She moved from one place to her current place for the same issues of she felt someone was getting in and messing with her stuff. But during our blow up she was saying you think I am crazy, I am not crazy and you will see one day. You want to have me committed don't you. I said absolutely not. I am worried about your health. Once she found out I called the doctor she wanted an explanation and I just felt I had to go ahead and tell her I thought she might have early stage Alzheimer's. She did not take it well at all and was deeply hurt and had to get off the phone.
