ADHD in children and adolescents

HKS (hyperkinetic disorder) or ADHD (attention deficit/hyperactivity disorder) is the most common mental illness in children and adolescents. For this reason the most widely discussed explanatory models are explained in the current 'bio-psycho-social model'. Scientists and psychologists agree that impulsive hyperactive and inattentive children and adolescents have always existed. Today however these traits are more pronounced and obvious so that the line between children and adolescents who require treatment and those who do not has shifted in recent decades. There are a variety of theories about HKS/ADHD with the view that modern industrial society with its extraordinary living conditions is responsible for this conspicuous behaviour in children and adolescents.
