i want to know if I should be concerned about my sons almost overnight behavior change. He has had your typical knock on the head accidents that boys have (some of them recent) and with his recent change in behavior, I mean off the wall, like Im thinking I cant believe this is my son, behavior changes, is it possible he has hurt his brain? He has always been a very good boy. The only things are; my husband and I have been going through a difficult time, but it has been going on for awhile, not really anything new that i would think would change his behavior sooooo drastically practically overnight. And he is very attached to me. But like I said he has always been a good boy, until recently. I have almost run out of patience and my husband ran out a while ago! Help. Thanks-LYNN
