friends need help, mentally ill grown son at home

[Ilsa]

5. He sounds like he is unmedicated and

unable to see the reality of his situation and the probable consequences of his behavior.

I think the parents need to talk to each other and decide how far they are willing to go in the event "abandoning" him becomes a recommendation. It sounds like they aren't willing to do this yet.

It also depends on whether the son has always been this way or had onset of his illness later, like in college. If it was later, I wonder if the parents could legally acquire guardianship of him. Then he legally would not have the right to refuse treatment, etc.

Too many unknowns. The parents need a lawyer, perhaps one who works with disability and guardianship issues.
