What causes oppositional defiant disorder (ODD)?

ANSWER

We don’t know exactly what causes ODD, but several factors may play a role:

  • Biological: ODD may be linked to defects or injuries to certain parts of the brain, or to faulty workings of brain chemicals. Many children and teens with ODD also have other mental illnesses, such as ADHD, learning disorders, depression, or an anxiety disorder, which may contribute to their behavior problems.
  • Genetics: Many kids with ODD have close family members with mental illnesses, suggesting that the condition partly may be inherited.
  • Environmental: Family problems, a family history of mental illnesses and/or substance abuse, and parents’ disciplinary habits may help lead to ODD.
