Are do all ADD ppl have anger issues?

ok my brother and mom have ADD. And i know 2 ppl at school who have ADD they all seem to have anger issues and get mad easily. My brother has broken the TV remote, smashed his burrito at the dinner table, broken a plate at the dinner table, thrown his milk shake at me in the car, cusses my out over the littlest thing, when i disagree with him he gets rlly mad and keeps going on and on and ends up freaking out, and plenty of other stuff. just want 2 know if im not the only 1 who has 2 deal with a ADD brother with anger issues. Also my mom gets mad easily 2 but nver throws or cusses or anything.
