Is the ADHD gene dominant?

Mutations in several genes that are normally very active in the prefrontal cortex and basal ganglia might play a role. Early tips suggest that faulty genetics underlie ADHD came from studies of the relatives of children with the disorder. read more

There is no single gene responsible for ADHD, but evidently a number of them affecting the function of, primarily, the areas of the brain that exert executive function -- the ability to monitor, direct, and coordinate the other brain functions.

 ADHD is a dominant trait and is not sex-linked; meaning that it is Autosomal Dominant Autosomal dominant is a way that a disorder is passed down through families. If you inherit the gene from one parent, there is a possibility of you receiving the disorder. read more

Yes, ADHD is genetic. This has been proven many times through the twin study. If a fraternal twin has ADHD then there is only a 40% chance that their twin will have it but if an identical twin with the same genes has it, then there is a 100% chance their twin will have it. It is a ressesive gene. read more
