Comorbid Conditions in Child and Adolescent Patients Diagnosed with Attention Deficit/Hyperactivity Disorder

Abstract

Attention deficit/hyperactivity disorder (ADHD) is one of the most common childhood psychiatric disorders. The worldwide prevalence of ADHD in children has been reported at 4-7%. Numerous population-and clinical-based studies have reported that more than half of cases of ADHD have at least one psychiatric comor-bidity. The presence of psychiatric comorbidities complicates the diagnosis, treatment , and prognosis of ADHD; thus, diagnosis of comorbidities is of great importance. Possible comorbidities should therefore be investigated in cases diagnosed with ADHD before treatment planning.
