My father hasn't been formally diagnosed with dementia, but doctors are saying that he is showing signs of early stage. He is suicidal, and has attempted twice with a knife. My mother is his primary caregiver, but she can no longer take care of him. I am not in a position to move into their home right now (but I would) and take care of him, but he needs around the clock care. My sister is an RN and she says he can't go home again, after a thwarted suicide attempt sent him to the hospital with a broken hip. He wants to be home, to die at home. How do we tell him that he needs to be in a place that can take care of him, that he can't go home? Is it too soon to put him in a home for proper care? Or is it an option, considering that he is suicidal? He's 71, and in fast decline. I'm so lost.
