Available evidence suggests that ADHD is genetic—passed down from parent to child. ADHD seems to run in at least some families. At least one-third of all fathers who had ADHD in their youth have children with the condition. What’s more, the majority of identical twins share the ADHD trait.
How rare is it to be born with ADHD?
Anywhere from one-third to one-half of parents with ADHD will have a child with the disorder. There are genetic characteristics that seem to be passed down. If a parent has ADHD, a child has more than a 50\% chance of having it. If an older sibling has it, a child has more than a 30\% chance.
What are the causes of ADHD?
The exact cause of ADHD is unknown but many medical studies have shown a strong genetic component and pinpoint developmental impairment of the brain’s executive function as a key component. 1 As such, the condition tends to run in families. Environmental factors and homelife may worsen (or improve) symptoms but do not cause ADHD.
Is there a link between birth weight and ADHD?
Evidence indicates that children with a low birth weight (less than 1500 grams or 3.3 pounds), or who experienced stress due to a complicated birth, are possibly more susceptible to developing ADHD.
What is ADHD and preterm birth?
