Attacking is probably the wrong word. It's likely frustration and disappointment. I get the feeling that the patient and his mother can't really grasp what's going on in their lives, and it makes me wonder whether he was chosen because they knew he was going to be a low-impact first trial patient - in the knowledge that if anything went wrong he and his family wouldn't have the faculties (neither intellectually nor financially) to cause trouble. Maybe I'm projecting, but I recognize this "vagueness" the author describes from certain patients back when I was a med student, it's not really a great sign if you need people to manage their illness. Getting accurate information from them is difficult and compliance is an issue - just as it's being described in the article.
