A new study out of Michigan State University has found a unique combination of factors that may contribute to ADHD in children. The study reviewed a specific genetic region of the brain associated with serotonin, and children’s tendency to experience psychological distress.

“In the study of 304 youths, researchers found that those children who reported more self-blame, and had variants in the region[of the brain] associated with both high and low serotonergic activity, had more ADHD symptoms… ‘Our work examines the interaction between a specific gene variant and a family environmental risk factor in order to determine their roles in the development of ADHD via behavioral and emotional dysregulation in children.’” (Source: PsychCentral)

The specific region studied, called 5HTTLPR, regulates the transmission of serotonin, and has previously been linked with a wide range of neuropsychiatric disorders. Researchers believe their study points to a genetic liability for ADHD, rather than a risk. The difference being that the liability is only an issue if certain environmental factors are present to trigger the ADHD.
