ADHD clearly runs in families, but the actual pattern of how it’s passed on from generation to generation is unclear. Researchers have begun to identify a variety of specific genes that show up more frequently in people with ADHD. This suggests that ADHD is a polygenic problem. That is, there are probably a variety of underlying combinations of genes that are responsible for the outward manifestations of ADHD that we observe. This awareness could help explain why there is so much variability in symptoms, severity and response to medications from ADHD individual to ADHD individual.
I anticipate that clarification of the genetic basis for ADHD will lead to dramatic improvements in our ability to diagnose ADHD, define specific genetic subtypes and more precisely treat ADHD. Until this type of information is readily available and turned into some type of a routine genetic test, we are left with relying on observations, interviews, questionnaires, and attention testing to identify individuals in a family with ADHD.
In my clinical experience, more than 90% of the parents of children with ADHD can identify another family member with similar problems. It might be a brother or a sister, an aunt or an uncle, or most commonly, one of the parents themselves. Sometimes it’s not called ADHD…maybe it’s depression, anxiety disorder, delinquency, or perhaps just “ditzy Aunt Sally” or “crazy old Uncle Harry.” If you look below the surface of these labels, you’re likely to find a history of ADHD behaviors or symptoms.
For many parents, sitting down and hearing that their child has ADHD helps them, for the first time, to understand the reason for difficulties they have experienced in their own lives. For some parents, accepting the ADHD diagnosis in their child forces them to accept that they have a problem too. Unfortunately, this painful realization causes a few parents to deny the ADHD diagnosis in their child.
In our clinical practice at The Being Well Center in Pittsburgh, we have many families where we see a child, Mom or Dad (or both), a grandparent and other extended family members. Based on our experience working with ADHD over many years, we make it a top priority to identify other family members who might have ADHD when we make the diagnosis of ADHD in a child, adolescent, or young adult. There are two important reasons to take some steps toward screening others in the family:
- First, when we can get all members of a family unit identified, properly diagnosed, and then appropriately treated, everyone benefits! Synergy occurs when the home environment is less chaotic, more structured routines are implemented, and systems are put into place to ensure better follow through with rules and responsibilities, use of compensating strategies and adherence to medication regimens…the whole is definitely greater than the sum of the parts when it comes to ADHD in families!
- Secondly, it’s simply good health care to accurately identify and treat a problem like ADHD which can be an unrecognized contributor to so many serious life dysfunctions across the life span. Identifying and properly treating ADHD can change someone’s life today and well into the future.
So, when it comes to ADHD, it’s important to remember: where there’s one there’s likely to be another. When I teach pediatricians, family physicians and psychiatrists about ADHD, I strongly encourage them to screen other family members of their ADHD patients and facilitate getting those individuals properly diagnosed and treated.
If you are a parent or close relative of someone with ADHD and your struggling in some aspect of your life, have a high degree of suspicion about ADHD in yourself. Complete an ADHD screener.
