This is about my brother, he had some kind of mood outbursts problem ans its been a long time now. He would be ok for like 6-7 months and then again after sometime he would become violent, doing weird things, always angry and ready to destroy things, beating people (family members), throwing stuff here and there. Situation gets very bad when he is like that. He would remain like this for sometime (say 6 months to an year) , then he becomes normal. Then after sometime he goes back into the same violent phase. This has been repeating for a long time now. He is 30+ and this has been happening to him since he was 15-16 or something like that. don't know which doctor should we consult ?
Thanks.
