ABSTRACT
Most children presenting to clinics and meeting the diagnosis of ADHD also have one or more comorbid disruptive behavior or emotional disorders (1). It is increasingly clear that consideration of these disorders is critical to sharpen our conceptualization of ADHD and its etiologies, to the diagnostic process, and to treatment choice and outcome. This chapter discusses the impact and implications of comorbid disruptive behavior, anxiety, and depressive disorders.
