The Revised Korean Practice Parameter for the Treatment of Attention-Deficit Hyperactivity Disorder (I): Clinical Presentation and Comorbidity

ABSTRACT

Attention-deficit hyperactivity disorder (ADHD) is a common psychiatric disorder that can affect individuals across their lifespan. It is characterized by the core symptoms of inattention, impulsivity and hyperactivity. ADHD develops as a result of the complex interplay between genetic and environmental factors. Children and adults with ADHD usually suffer concomitantly from other psychiatric comorbidities, including both externalizing and internalizing disorders. It is associated with functional impairment and poor long-term outcomes. This review aims to summarize the key findings from recent research into ADHD and its prevalence, core symptoms, cause and comorbidities from childhood to adulthood.
