Our 82 year old mother has been going through worsening dementia that started almost three years ago. She believes that her old neighbors (she has since moved) are out to get her. They come to her house and throw rocks at her windows, play music on her balcony, put dirt on her car, etc. She even believes that the ex-neighbor has convinced the man downstairs to move in with him, so she can harass my mother more easily! She often describes laughter directed at her because her old neighbors are getting the best of her. The police has also been called numerous times to 'catch' these people in the 'act'. She is angry, judgmental, has a flat personality, hangs up on her sons, and trusts no one. She thought the couple who lives on the end of the building were in her condo when she went out! We have suggested taking her to get checked out, but she violently refuses. When we express doubt in her auditory and visual hallucinations she lashes out. She still lives by herself (and is still driving). We believe she can benefit from therapy, and most likely, medicine. Question is.....how do we go about getting her to a doctor without alienating her from the family, or causing her paranoia to completely take over?
