Well, what a difficult situation. I'm guessing that since the friend with the mother is talking to you, that the family has become worried. Perhaps someone could suggest that the mother be taken to her doctor for an evaluation. Her doctor could then make a determination as to whether the symptoms are physical or mental and then make the appropriate referral for appropriate treatment. Sometimes, what sounds like a mental health problem can actually be a sign of dementia
or some other medical problem. So, the first place to start would be with the doctor. Once a medical evaluation has taken place, the family would have a clearer picture of how to proceed.
In the meantime, as to your question regarding a response to bizarre remarks, the best course of action would be to be generally respectful of the mother. It is usually not helpful to argue or try to be rational with someone who is irrational. However, if she sometimes responds positively to some logic, then the people who speak with her can make the attempt to help her "test out" her irrational belief of the moment or repeat their conversation to her in a different way so as to make sure that she is understanding what is being said. When I'm in counseling with someone, if the client does not seem to understand the meaning of what I am saying, I will say it in a different way so that they might understand better what is being said or asked. In your particular case, I would be respectful, try to re-state what I am saying so that she can understand better, then if that doesn't work, I would not engage in a negative argument. The botXXXXX XXXXXne is that she needs to see her doctor about these symptoms.
