W H AT W E K N O W ADHD and Coexisting Conditions: Disruptive Behavior Disorders Attention-deficit/hyperactivity disorder (ADHD)
is a common neurobiological condition affecting
5-8 percent of school age children1,2,3,4,5,6,7 with symptoms persisting into adulthood in as many as 60 percent of cases (i.e. approximately 4% of adults). 8,9 In addition,
approximately two thirds of children with ADHD have at least one other
coexisting condition.10As can be seen, any disorder can coexist with ADHD, but certain disorders such
as the disruptive behavior disorders seem to occur more commonly.11This What We Know Sheet deals with the common disruptive behavior disorders
oppositional defiant disorder (ODD) and conduct disorder (CD). Having one
of these coexisting Disruptive Behavior Disorders (ODD/CD) can not only
complicate the diagnosis and treatment but also worsen the prognosis. Even
though many children with ADHD ultimately adjust, some (especial y those with
an associated conduct or oppositional defiant disorder) are more likely to drop
out of school, have fewer years of overall education, have less job satisfaction and fare less well as adults.12 Early diagnosis and
treatment of these conditions is by far the best defense against these poorer
