About 8 months ago he got into an argument with my mother just because she was pressuring him to follow up on his college application and things escalated quickly. He started telling her to shut the **** up, called her a *****, and was telling her to suck his d**k. It pissed me off so bad that I yelled at him through his door and he went downstairs to the kitchen, got a knife, and started coming up the stairs towards me and my mom. My dad had to talk some sense into him and was able to get him to hand him the knife. He seemed to be remorseful after my dad talked to him but he continues to act on impulse. There are more incidents but it would make this post way too long.
I did some research and thought that it could be Intermittent Explosive Disorder but i'm not sure. My dad knows something is wrong with my brother but my mother is in denial.

@Man8 My father thought about bringing him to a specialist but my mother is in denial and the idea causes arguments between the both of them. Since my mother is in denial my father just leaves the situation alone to keep the peace even though he knows something is wrong with my brother.
