- Disruptive, impulse-control, and conduct disorders refer to a group of disorders that include oppositional defiant disorder, conduct disorder, intermittent explosive disorder, kleptomania, and pyromania. These disorders can cause people to behave angrily or aggressively toward people or property. They may have difficulty controlling their emotions and behavior and may break rules or laws.
- Most kids will act up or become disruptive or defiant sometimes. Disruptive and conduct disorders, however, involve much more severe and longer-lasting behaviors than typical, short-lived episodes.
- An estimated 6 percent of children are affected by oppositional defiant disorder or conduct disorder. Each year, an estimated 2.7 percent of children and adults in the U.S. are affected by intermittent explosive disorder. Kleptomania and pyromania are rare, affecting 1 percent or fewer people in the U.S.
