Is ADHD more genetic or environmental?

ADHD is highly heritable, with twin studies in children suggesting 70–90% of the variance between individuals is due to genetic factors, and 10–30% due to unique environmental factors (specific to each twin; Jepsen & Michel, 2006).

Can you develop ADHD from environment?

ADHD is a complex disorder caused by multiple factors, making it difficult to identify the exact causes. Genetic and environmental factors, and their interactions, are known to contribute to this disorder. Environmental factors include maternal smoking during pregnancy and duration of breastfeeding.

What percent of ADHD is due to genetic factors?

While the exact causes of ADHD have not been identified, genetic studies show there is a strong hereditary component, with an up to a 91 percent likelihood of passing the disorder to your children.

Environmental factors don't directly cause ADHD. At least, not on their own. Nature, aka genetics, plays a big role. But your environment can also contain factors that lead to ADHD.

Due to this lack of dopamine, people with ADHD are "chemically wired" to seek more, says John Ratey, M.D., professor of psychiatry at Harvard Medical School in Boston.

Is ADHD a chemical imbalance?

Impairments of ADHD are not due to a global excess or lack of a specific chemical within or around the brain. The primary problem is related to chemicals manufactured, released, and reloaded at the level of synapses, the junctions between certain networks of neurons that manage the brain's management system.
