Attention deficit/hyperactivity disorder and ethnicity.

Abstract

Despite the large volume of research dedicated to attention deficit/hyperactivity disorder (ADHD), the influence of ethnicity on the condition is still to be adequately addressed. Previous studies have shown differing rates of ADHD between different countries (although this can be affected by the assessment tool used). Cultural environment may affect a child's behaviour, but the differing attitudes of parents, clinicians, and society around the world towards acceptable behaviour may also influence diagnosis. If assessment criteria could be consistently applied across different ethnic groups, the prevalence of ADHD would probably be similar.
