   What causes ADHD?

   • Researchers have been unable to identify a single cause for ADHD. A combination of genes, environmental factors, and possibly diet seem to influence the likelihood of a person developing ADHD. Some research suggests genes are the largest factors in determining who develops ADHD. After all, genes are the building blocks for our bodies.

   Does ADHD have genetics?

   • As research has narrowed in on what causes ADHD, scientists recognize the strong role genetics play. Therefore, much of the research into ADHD is devoted to understanding genes. In 2010, British researchers identified small pieces of DNA that are either duplicated or missing in the brains of children with ADHD.

   Is ADHD a genetic phenotype?

   • There is substantial evidence for a genetic contribution to ADHD, with a mean heritability of 76% demonstrated in twin studies. It has been hypothesised that several genes may interact to cause ADHD, or that ADHD may be the common phenotype for numerous variant alleles.

   Do genetic variants increase the risk for ADHD?

   • With the discovery of these functional variants, we will learn more about the mechanisms whereby genetic risk variants increase the risk for ADHD. Accumulating evidence from family, twin, and molecular genetic studies suggests that the disorder we know as ADHD is the extreme of a dimensional trait in the population.

   Is ADHD a risk factor?

   • There is an increased risk of ADHD, or attention deficit hyperactivity disorder, in those who have a parent or sibling with the condition, but doctors know that other factors also play a role. ADHD can affect attention, behavior, and learning.

   Are genes involved in the etiology of ADHD?

   • Family, twin, and adoption studies provide a firm foundation for asserting that genes are involved in the etiology of ADHD. The view from molecular genetics provides a basis for understanding mechanisms whereby genes affect biological pathways that lead to ADHD.

   Genetics. ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.

   Jun 11, 2018 · ADHD’s high heritability of 74% motivated the search for ADHD susceptibility genes. Genetic linkage studies show that the effects of DNA risk variants on ADHD must, individually, be very small.

   People with genetic changes associated with ADHD generally inherit an increased risk of developing the condition, rather than the condition itself. When ADHD is a feature of another genetic syndrome, it can be passed on according to the inheritance pattern of that syndrome.
