ADHD Comes from Which Parent? Understanding the Genetic Story Behind ADHD
If you’ve ever found yourself wondering — or even googling — “ADHD comes from which parent?”, you’re not alone. This is one of the most common questions parents ask when their child receives an ADHD diagnosis. It’s natural to wonder whether it’s something passed down from mum, dad, or somewhere further back in the family tree.
As both a qualified ADHD parent coach and a mum with lived experience, just ahead of you on this parenting road, I want you to know this: understanding where ADHD comes from can help — but what matters most is how you show up for your child today. Let’s explore the latest research into genetics, family history, and environmental factors, so you can feel confident and informed as you parent your unique child.
What is ADHD?
ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurological developmental disorder that affects approximately 5-7% of school-aged children. That means in a typical classroom, one or two children may be navigating ADHD challenges like impulsivity, inattention, and hyperactivity.
ADHD affects more than just learning — it can impact social interactions, self-esteem, and emotional regulation. And while ADHD is one of the most researched childhood disorders, the exact causes aren’t fully understood. What we do know is that ADHD often runs in families, which points to a strong genetic component. So, if you’re wondering whether ADHD comes from mum or dad — the answer is: it could be either (or both).
Genetics and ADHD: Is ADHD Inherited?
Research consistently shows that genetics play a significant role in the development of ADHD. Studies have found that parents and siblings of children with ADHD are 5 to 10 times more likely to have ADHD themselves.
This means that either parent — mum or dad — could pass on the genetic traits linked to ADHD. But here’s the important thing to know: ADHD doesn’t have a single genetic cause. Instead, multiple genes work together, interacting with environmental factors, to influence how (and whether) ADHD presents in your child.
Can Environmental Factors Cause ADHD?
While genetics create the foundation, environment plays a role too. Factors like:
- Prenatal exposure to smoking or alcohol
- Pregnancy complications like preeclampsia
- Premature birth or low birth weight
- Exposure to environmental toxins in early childhood
These influences don’t directly cause ADHD — but they can increase the risk, especially when combined with a genetic predisposition. Understanding this mix of nature and nurture can help parents let go of guilt and focus on what you can control today.
The Role of Family History in ADHD
If you or your partner (or even a grandparent) have ADHD, your child’s risk increases significantly. ADHD can also skip generations, so even if you don’t personally have ADHD, a family history on either side could play a role.
Interestingly, parents with ADHD often bring unique strengths to parenting their ADHD child — including deep empathy and a personal understanding of what it feels like to navigate a neurodivergent brain.

How to Recognise ADHD in Your Child
If you’re wondering whether your child has ADHD, it’s important to understand that ADHD exists on a spectrum — no two children present exactly the same. However, some common signs to watch for include:
- Persistent inattention or lack of focus, even in situations that interest them.
- Impulsive behaviours that seem risky or poorly thought through (this is developmentally age appropriate)
- Hyperactivity that’s difficult to manage across different settings (home, school, social activities).
Early diagnosis and early support for parents make a world of difference. When parents have the right tools and strategies, they can reduce family stress, build stronger parent-child connections, and empower their child to reach their potential.
Does ADHD Come from Mum or Dad? What Matters Most
The truth is, ADHD doesn’t belong to mum or dad alone. It’s a complex mix of genetics, environment, and unique child factors — meaning there’s no need to blame yourself (or your partner). Instead, the most important thing you can do is focus on the here and now.
As a parent, your superpower isn’t knowing whether ADHD came from you — it’s learning how to parent confidently, advocate effectively, and create a family environment where your child feels safe, supported, and understood.
