Gene Variant Linked to ADHD

Scientists at the National Institute of Health have conducted a study which found a genetic link to ADHD and promises improvement over time. The gene, called DRD4, seems to increase the risk for ADHD in younger children by causing brain areas that control attention to be thinner. However, as the children get older, this gene appears to be associated with a normal thickening of the same areas of the brain.
"Although this particular gene version increased risk for ADHD, it also predicted better clinical outcomes and higher IQ than two other common versions of the same gene in youth with ADHD."
The DRD4 gene appears to account for about 30 percent of the genetic risk for ADHD. Read more at MedicalNewsToday.com.
