Step-by-step explanation:
The subject of this question is Oppositional defiant disorder (ODD).
Oppositional defiant disorder (ODD) is a behavioral disorder characterized by angry or irritable mood, argumentative and defiant behavior, and vindictiveness. The symptoms must persist for at least six months and should be significantly disruptive to the individual's daily life. ODD is often diagnosed in childhood and can coexist with other disorders like attention-deficit/hyperactivity disorder (ADHD) or conduct disorder (CD).
It is important to note that while ODD shares some similar symptoms with ADHD, they are different disorders. ADHD is characterized by difficulty maintaining attention and controlling impulses, while ODD is characterized by oppositional and defiant behavior.
