Children with conduct disorder tend to be impulsive, hard to control, and not concerned about the feelings of other people.
Symptoms may include:
These children often make no effort to hide their aggressive behaviors. They may have a hard time making real friends.
There is no real test for diagnosing conduct disorder. The diagnosis is made when a child or adolescent has a history of conduct disorder behaviors.
A physical examination and blood tests can help rule out medical conditions that are similar to conduct disorder. Rarely, a brain scan may also help rule out other disorders.
