Researchers Link 27 Genetic Variants to ADHD Feb. 9, 2023 — A large international study has identified 27 loci in the human genome with genetic variants that increase the risk of ADHD.

and attention deficit hyperactivity disorder (ADHD) is well established, the causal mechanism of this relationship remains ambiguous. We aimed to investigate whether common genetic and/or ...

The study suggests that a genetic change in the dopamine transporter - one of the brain's dopamine-handling proteins might lead to ADHD. While studying two brothers with ADHD, the researchers ...

Some mental health conditions have genetic components, and the same can be said for attention deficit hyperactivity disorder (ADHD). Research have some insight into the genetic component of the ...

In one of the largest-ever studies of DNA and brain volume, researchers have identified 254 genetic variants that shape key structures in the “deep brain,” including those that control memory, motor ...
