Ryan is a 12 year old diagnosed with Oppositional Defiant Disorder ODD

Ryan is a 12 year old diagnosed with Oppositional Defiant Disorder (ODD). As a small child, Ryan was first diagnosed with Attention Deficit, Hyperactivity Disorder. He had just started preschool and was unable to remain in one place for more than a minute or two. His parents had already had a very difficult time in disciplining him, because he would become very upset and throw temper tantrums when he could not do as he wished. He just seemed to be an unhappy, irritable child. This behavior continued in school. As time progressed, Ryan was diagnosed with Oppositional Defiant Disorder, because he continued to refuse to listen to adults and comply with the rules.
By the age of 12, he has begun to bully and annoy others. His parents have decided that the approaches they have used in the past are not working, and they are more afraid his behavior will only get worse.
