Oppositional Defiant Disorder, or ODD, was one of Lilly’s main diagnoses. It pretty much means that you will be defied on every level if power is at stake. Kids that have this seem to enjoy refusing to do what you want. They will disobey, argue, and cause trouble.
There are possible causes of ODD: biological, environmental, or genetic. ODD is usually seen with other disorders such as ADHD.
