A genetic study of ADHD and activity level in infancy.

ABSTRACT: It is well known that there are strong genetic influences on attention-deficit hyperactivity disorder (ADHD), with genetic association studies providing good evidence for the involvement of the dopamine neurotransmitter system in its aetiology. Developmental origins of ADHD represent an interesting area of research to understand the genetics that underlie early appearing individual differences. However, understanding the molecular basis of ADHD requires accurate, unbiased, heritable measures that can be used for molecular genetic association analyses. We take two approaches to examine the genetics of ADHD behaviours in infancy. Using quantitative genetic techniques, we explore the relationship between objective measures of activity level (AL) in both home and laboratory environments as wel
