title: Unravelling the complexity of attention-deficit hyperactivity disorder: a behavioural genomic approach.
abstract: International research has established that there is a strong genetically inherited contribution to attention-deficit hyperactivity disorder (ADHD) and the genetic mechanisms involved are being sought with considerable success. It is now established that certain alleles of the genes coding for the dopamine D4 receptor and the dopamine transporter occur more frequently in children with ADHD than in healthy controls, and we are finding other DNA changes associated with ADHD. A major challenge for the field now is to clarify how genetic susceptibility is translated into disorder by integrating the fields of quantitative and molecular genetics, neuropsychology and environmental risks.
