ADHD and its relationship to comorbidity and gender [PhD Thesis]Attention deficit hyperactivity disorder (ADHD) is the most common neuropsychiatric disorder of childhood and constitutes approximately 50% of referrals to child and adolescent mental health clinics. The disorder is associated with negative impact on families and both academic and vocational outcomes. Estimated prevalence is approximately 3%- 7% in school-age children according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR), published by the American Psychiatric Association in 2000, but rates of ADHD vary depending on race and ethnicity, gender, and age. Diagnostic rates are on the increase with accompanying financial burden to health care services.
