My dad has had dementia for years but this last year he has had confabulations which have escalated to epic proportions. He thinks my elderly mother is having an affair and he’s aggressive and a danger to her. He has already threatened to kill her. He has been put on antipsychotic medication but is refusing to take it. Our only hope for her safety is that he takes the meds, and we’re at a loss as to handle this situation. Any help appreciated.
