My 89 year old mother is living close by in her own apartment. About 3 weeks ago she began accusing family members of breaking into her apartment and moving things around, taking batteries out of her remotes, and other nuisance related behaviors, in an attempt to make her feel as if she is losing it. She is not threatening to call the police on family members. I attempted to assure her that I will help her get to the bottom of this situation and have changed locks, added additional locks, brought my dog over, changed code on her alarm, etc. with no avail. Now she is threatening to call the police on an innocent family member. I am call for a Dr.'s appt. today and hope I receive some answers, but not sure what to do if there are no answers to situation.
