Collaborative possibilities for molecular genetic studies of attention deficit hyperactivity disorder: Report from an international conference

Research on attention deficit hyperactivity disorder (ADHD) suggests that A DHD has a substantial genetic component. Although still in their infancy, m olecular genetic studies have already implicated several genes as mediating susceptibility to ADHD, Nevertheless, given that ADHD's mode of inheritanc e is likely to be complex, much more work is needed to fully clarify the ge netic architecture of the disorder. Because large samples and collaborative efforts will likely be needed to attain this goal, researchers in the fiel d have convened a series of meetings to discuss measures for assessing ADHD , the feasibility of using common measures across sites, ways to increase c ommunication among researchers, and strategies for defining genetically use ful phenotypes.
