Has anyone here experience pa/pas? If so have you been successful at beating this in the courts? Whats your methods? Tell me your story, please

A very close friend of mine is experiencing this with her 2 sons. Fortunately 1 of her sons gotten older he seems to waking up from the brainwash that his father placed on him a few years ago. Unfortunately however my friends youngest son seems to be having a major impact on him from the brainwash that his father placed on him. The youngest son that I knew (lets call him Joe) would never use the F word to his mother. Since his time with his father he is getting progressively worsen. Not that long ago he was hospitalized for pulling out a knife to his mother. Joe is obviously suffering from the worst case of PAS according to what said on http://www.paskids.com/pas/stage3.php

The courts seems to be failing not just for my close friend but its also failing for Joe.

Just how can you fight for this kind of child abuse in the courts when the American Psychological Association doesn't even recognize this as a real problem according to their statement at http://www.apa.org/releases/passyndrome.html?

I want to help my friend so bad but theirs so much that I can do to help her during this event. It kills me because I truly love her kids. I view them as my little brothers and sisters because I'm the only child.
