My son has adhd, an is taking concerts for it, he gets in trouble a lot an acts like he can't help it. is behavior issues associated with adhd?

Yes: In adhd, the child can have a lot of impulsiveness, hyperactivity, and poor attentiveness to instructions. All these areas can cause behavioral disturbances and get him in trouble in school -- or anywhere quiet, focused behavior is required. Behavioral training is important along with use of stimulant medications. Some of this can be practiced in school, in therapy, and at home.
