My brotheris thirteen and has had these anger outbursts and behavioral problems for a while now (5 years). He doesn't have any disorders or ADHD or anything like that that we know of he has never been diagnosed with anything. Basically his behavior is like this, he will have these random anger outbursts and get mad over the littlest things. Often when he has these putbursts he will cuss and alot and it getting harder for my mom to deal with it. Also often he will act like a two year old, if I clean something like say the living room he will go in there and mess up again then when I clean it up again he will try to get attention from me. And he won't listen to the rules and instructions and he doesn't take discipline very well. He makes these really gross jokes and I don't know where he got them from. I just want to know if my brother is going though a phase or if he has something else. My grandpa died four years ago, he and my brother were really close I wondered if this was his way of dealing with the loss but its been so long and he still acts the same. Is this like ADHD or ODD? I just need to know.
