Nearly two-thirds of teenagers in the U.S. have acknowledged that they have experienced fits of anger - severe enough to the point that they threatened violence, damaged property or were violent towards another person, according to a new study from Harvard Medical School.  The research suggests that these attacks of rage are more prevalent among teens than previously thought.

To add to these findings, the study also found that one out of every 12 adolescents in the U.S. - translating to nearly six million teenagers - could be diagnosed with Intermittent Explosive Disorder (IED), a condition in which a person is plagued by uncontrollable anger attacks unrelated to a specific mental disorder.

Based on a national survey of 10,148 adolescents -  the National Comorbidity Survey Replication Adolescent Supplement - the findings revealed the need for identify and treating IED early, possibly through school programs, the researchers said.
