Abstract
This article addresses the relationship between attention deficit hyperactivity disorder (ADHD) and academic problems. The development of diagnostic categories of attention deficits from the Diagnostic and Statistical Manual of Mental Disorders (3rd ed.) to the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) is briefly reviewed. Forty‐five Chilean children demonstrating symptoms of either ADHD Combined Type, ADHD Predominantly Inattentive Type, or ADHD Predominantly Hyperactivity‐Impulsive Type are compared with each other and with a clinical control group on the prevalence of academic achievement problems. The data show that academic problems are more common among ADHD Combined Type and ADHD Predominantly Inattentive Type children. Different reasons for the perceived co‐occurrence are discussed.
