My mom was diagnosed with dementia a few months ago. All of a sudden she believes my dad is having an affair. Everything she doesn't remember or recognize in the home is now attributed to the 'other woman.' There is no talking her down as she doesn't believe anything anyone tells her outside of her own delusions. We have tried everything - redirecting her, changing the subject, talking about it, not talking about it, medications, etc. Nothing has worked. When she's in the middle of an episode, she will yell at him, follow him around the house, wake him from a dead sleep, etc. It's becoming more frequent and her level of anger is increasing as well. My dad is her primary caregiver and it's just not working. I don't know what to do. Has anyone dealt with this and had something actually work? I thought the medication would help but it's not made a bit of difference. The rate at which this is increased is rather alarming too. It's very frustrating that there aren't any solutions right now. I'm worried she'll start to become violent as her rage increases. If anyone has any suggestions, please let me know.
