If ADHD is a spectrum condition, is it also true that “Everybody has a little ADHD”? Pretty much! For those living with the reality of ADHD, hearing that “Everybody has a little ADHD” can be frustrating, even infuriating. It can feel dismissive, as if ADHD is nothing more than a quirky personality trait instead of a developmental disability that can affect every facet of life.
Yet, as much as this phrase might sting, it also touches on a fundamental truth about ADHD: It exists on a spectrum. The human spectrum.
In other words, ADHD is not a binary condition where you either have it or you don’t. Instead, it’s dimensional. In fact, ADHD symptoms can be present to varying degrees in all of us humans. That’s why we might better think of ADHD symptoms as human traits.
ADHD Symptoms, Not ADHD Diagnosis
There’s a difference!
The ADHD diagnosis requires more than a symptom or two. It requires a certain number of symptoms along with evidence of struggle in multiple areas of life (e.g. education, relationship, employment, driving, etc.). And the challenges cannot otherwise be explained by low intelligence or other factors. Even among those who do meet ADHD diagnostic criteria, there is enormous variability. (For more info, check out my post on How the ADHD Diagnosis Is Made)
The idea that ADHD traits can be found in most everyone actually helps to explain why so many people might identify with certain aspects of the condition — even if they don’t meet the full diagnostic criteria. By understanding ADHD as a dimensional condition, we can help:
- Build bridges of understanding and compassion
- Reduce stigma as well as “denial”
- Promote higher standards of care
Research Finds ADHD Symptoms on a Spectrum in the General Population
Barbara Franke, PhDIn this post, I’ll share findings from an important study on this topic from a respected ADHD expert, Barbara Franke, PhD, whose scientific specialty is molecular signal-transduction. She studies the influences of genetic factors on mental health problems and traits such as ADHD.
Her research focuses on understanding the genetic contribution to neurodevelopmental psychiatric disorders, especially ADHD and its comorbidities. Beyond gene-finding, she uses complementary approaches (bioinformatics, i-neurons, small animal models, neuroimaging genetics) to map biological pathways from gene to disease.
Dr. Franke led this research team at the Donders Institute for Brain, Cognition, and Behavior in the Netherlands. Lead author is Li Ting, MD.
The team’s findings provide compelling evidence that ADHD exists on a continuum in the general population. This is not a new idea in the field of ADHD. (In fact, I explain this in both of my books and online training.). This research, however, underscores the idea with data.
I share this research because the public and much of the mental health field remain unaware that ADHD is a dimensional condition.
ADHD Is a Spectrum Condition, Not a Checkbox
Their paper is titled ADHD symptoms in the adult general population are associated with factors linked to ADHD in adult patients. It was published in 2019 in the Journal of European Neuropsychopharmacology. (That link gives you access to the full paper.)
The study looked at nearly 5,000 adults and examined how common factors linked to ADHD in clinically diagnosed patients also showed up in people who didn’t necessarily meet the full criteria for the disorder. The researchers compared diagnosable ADHD to the presence of ADHD symptoms in the general population that do not necessarily meet the full diagnostic criteria (i.e., sub-threshold symptoms).
To be clear:
• Diagnosable ADHD: This refers to individuals who meet the full criteria for an ADHD diagnosis according to the DSM-V. This includes a certain number of symptoms (inattention and/or hyperactivity/impulsivity) that cause significant impairment in daily functioning.
• Sub-threshold ADHD symptoms: These are the symptoms that individuals in the general population might experience, but they don’t meet the full criteria for an ADHD diagnosis. For example, someone might have several symptoms of inattention or hyperactivity/impulsivity, but not enough to meet the criteria.
What did researchers find? The short answer is that ADHD-like traits, such as inattention and hyperactivity, are present across the population. But, again, these traits don’t always reach the threshold that would warrant an ADHD diagnosis. This research supports the idea that ADHD is dimensional—meaning that the same factors that contribute to ADHD in a clinical setting also exist, to varying degrees, in everyone.
The Role of Childhood Symptoms and Personality Traits
A key finding of this study is the role of childhood ADHD symptoms.
The researchers found that adults who exhibited ADHD symptoms as children were more likely to continue experiencing these symptoms later in life. That’s true even if they didn’t meet the full criteria for an ADHD diagnosis. This mirrors what we’ve long known about ADHD: It’s a lifelong condition that often starts in childhood and persists into adulthood.
But it’s not just about childhood symptoms. The study also looked at personality traits including
- Neuroticism (emotional instability)
- Psychoticism (a tendency toward hostility)
- Extraversion (being outgoing and social)
They found that people who scored high on neuroticism and psychoticism were more likely to have ADHD symptoms. By contrast, those who were more extroverted tended to have fewer symptoms. This connection between personality traits and ADHD symptoms further supports the idea that ADHD isn’t an all-or-nothing condition. Rather it is influenced by a variety of factors.
Age and Gender Matter, Too, In ADHD Spectrum
The study also revealed interesting insights into how ADHD symptoms change with age and differ by gender.
For example, as people age, symptoms of hyperactivity and impulsivity tend to decrease, while inattentiveness remains relatively stable. This aligns with what we see in clinical practice, where adults often report more challenges with inattention than with hyperactivity.
Gender differences were also observed. Women were more likely to report inattentive symptoms than men, which could explain why ADHD in women often goes undiagnosed or is diagnosed later in life. Additionally, anxiety—a common comorbidity in ADHD—was found to particularly affect hyperactivity and impulsivity in women, highlighting the need for gender-sensitive approaches to ADHD care.
Why Understanding ADHD as a Spectrum Matters
Again, why does it matter that ADHD is dimensional? The researchers echoed my points in the introduction of this post.
First, it can help reduce stigma.
When we understand that ADHD traits exist on a spectrum and that many people exhibit some of these traits, it can help normalize the conversation around ADHD. Instead of seeing it as a label or a flaw, we can start to see it as a variation in how brains function. It’s much the same with vision. Few humans have perfect eyesight and the range of issues also runs on a spectrum. Few hesitate to support better eyesight with eyeglasses.
Second, recognizing ADHD as a spectrum can lead to better care.
If clinicians and the public understand that ADHD symptoms can vary in severity, we might be better equipped to identify and support those who struggle with sub-threshold symptoms that still impact their lives. This could mean more tailored interventions, earlier detection, and ultimately better outcomes for those with ADHD.
Bridging the Gap Between ADHD Research and Real Life
The study findings provide a bridge between what we see in clinical settings and what many people experience in their daily lives.
If you’ve ever felt like you have “a little ADHD” but didn’t think it was serious enough to seek help, this research suggests that you’re not alone—and that your experience is valid.
Then again, as the researchers emphasize, it’s important to remember that while many people may experience some ADHD-like traits, diagnosable ADHD is a serious condition that can be deeply disruptive. If you’re struggling with symptoms that interfere with your daily life, it’s worth talking to a healthcare provider. Effective treatments are available, and understanding your unique experience with ADHD is the first step toward managing it.
In conclusion, while the phrase “Everybody has ADHD” might be aggravating, it also reflects a deeper truth: ADHD exists on a spectrum. Recognizing this can help us better understand the condition, reduce stigma, and improve care for those who need it most.
Whether you’re dealing with “full-blown” ADHD or a few traits, knowing that these experiences are part of a broader human spectrum can help you feel less alone—and more empowered to seek the support and tools you deserve. I’ve always said that the strategies that are useful to people with ADHD are useful to everyone. That includes creating external supports to Executive Functions, such as around planning and managing time and priorities.
What about you?
Are you annoyed when someone seemingly dismisses your challenges with “Oh, I think everybody has a little ADHD”?
Or are you the one who truly believes that “we all have a little ADHD?”
I’d love to know how you feel about this. Please leave a comment.

I don’t agree that it’s a spectrum in this PARTICULAR way (it’s definitely a spectrum within those who have it). Yes, ADHD traits can be found in the general population. But from my understanding and reading, there is literally a difference in brain structure. Pathways aren’t the same, things don’t fire in the same areas. So saying “everyone is a little ADHD” completely ignores the physical differences for the sake of appearances. Which I never approve of.
Everyone is entitled to their opinion. :-). And everyone in social media and elsewhere is sharing all kinds of opinions, many of them based on superficial understandings of complex issues.
Me, on important issues, I prefer to seek the consensus of people who trained many years to study these topics and are respected in their field.
The fact is, ADHD symptoms are human traits. It is the number, degree, and significance in daily life that makes the diagnosis.
There are no “ADHD genes”. ADHD is associated with potentially hundreds of genetic contributors, all found in distribution in the human genome.
The differences in brain structure issue…often misunderstood. This is something that shows up only in the aggregate, with huge numbers of study subjects. It involves factors such as slowed cortical growth. It does not show in individuals.
I’m not here to argue these points. Just to present the expert views.
I hope that we can stop the “ADHD vs. Neurotypical” wars that have been fomented by online personalities seeking followings and “likes”. It serves no one. Most especially not people with ADHD.

Oh, I am SO annoyed when someone says they think they have a little ADHD because they misplace their keys occasionally, or whatever. I have a LOT of ADHD. I have a law degree and a Ph.D–and am on SSD disability because, despite skills, grit, medication, and trying my hardest, I can’t hold down a full time job. Organizing, forgetting to do things, obsessing over some details but not noticing others, losing or misplacing stuff (and some “emotional dysregulation,” which I often keep to myself)–these are often daily challenges for me. Spectrum or no spectrum, there’s a big difference between full-blown AD/HD and occasional lapses in attention. I think that the spectrum concept could lead people without diagnosable AD/HD to equate their own experience with those, like me, who do have it–and that wouldn’t help them understand the impact of this condition.
Hi Julie,
thanks for your comment.
Of course it’s annoying, as I acknowledged at the beginning. And there IS a difference between traits or symptoms and diagnosis, as I also acknowledge.
I’m just suggesting a shift in perspective, one that might open minds and increase empathy.
The average schmoe might lose their keys a few times a month. Some folks with ADHD might lose their keys a few times a week.
Whether we like it or not, ADHD symptoms are human traits. Some of us are more human than others — and even they are more human in variable ways. 🙂
cheers.

Thanks. Folding is tempting but I guess AuDHD is stubborn and resilient. I think that AuDHD is resilient by design – we are often undiagnosed for so long and having to deal with two opposing conditions ASD and ADHD – which will never be at peace with each other makes us resilient, even though we feel every emotion exponentially more (during and afterwards where we replay everything to try to see what we could do better) – we still bleed. Woe betide anyone who attacks my ASD my ADHD will be there to defend. Some of my trauma (ADHD forgets a lot) is to do with being legally attacked by my own family because they misunderstood my then minor (perhaps annoying) AuDHD symptoms; ironically I have strong reasons to suspect my two daughters and son who are all successfully creative are AuDHD at some masked (supported) level.
Kind of crazy to be in this situation, to finally meet my AuDHD brain – not so much a Black Sheep more like an electric blue Unicorn. I think masking is a survival instinct all of us can do depending on the environment; we often are not allowed to be ourselves due to boundaries and rules – AuDHD cares more about people than those constraints.
There is a possibility that evolutionarily the more exposed male carries risky genes on the X that tend to be more masked on females and this could account for some of the disparity in diagnoses. Of course, given my track record of 1 comprehensive diagnosis out of about 8 other incomplete or blatantly incorrect ones, misdiagnosis and missed diagnosis is common for many folk for conditions that are invisible, neurological (hardware) and can cause and thus be conflated with psychological issues (system software) and behavioural issues (the app you are currently running). Being kidnapped by a MHU and accused of having mania in January when I am dealing with unmasked ASD/ADHD amplified by stress and I have no time to deal with PTSD or anxiety and depression. Trying to convince a psychologist clearly out of their depth is hard. I am gifted (whatever that means) so I tend to be good (until I lose interest) at anything I am wanting to learn. It is validating to meet others like me – mostly female AuDHDers so I wonder where all the males are? Statisitics reflect some of reality modulated by how they are collected.
I’m glad your tag team is in your corner. 🙂

I suspect a large proportion of masked inattentive males do not report or even get diagnosed. Could it be that men do not seek help for invisible conditions that are so diverse as to be conflated with psychological or behavioural issues. I did not get diagnosed for my AuDHD until after 65 when it had unmasked and amplified due to medical and personal trauma. I am in the process of writing a book or two on my lived experience, a journey involving 4 related cancers since the age of 3 and two opposing masked neurological conditions and a good dose of personal trauma. The lack of understanding of AuDHD is even more so than ADHD or ASD separately – and none of those are understood in society well either. If women with undiagnosed masked AuDHD go through menopause it can cause absolute confusion and chaos. I did not have that hormonal stressor, I had about a decade of hypecalcaemia which can cause long term effects on the brain. Still trying to understand it all and defend myself. Only those with AuDHD and similar challenges (environment dependent) would understand.
Hi Harold,
Thanks for your comment. Absolutely, millions of even-not-so-masked males do not report or get diagnosed. It’s bad enough in the U.S., where access to care is comparatively easy. Imagine in the rest of the world.
Yet many women remain “in denial” of their ADHD challenges. It’s often part of the syndrome, low insight.
Four cancers since age 3 on top of everything else. You have my sympathies. But how strong you must be. I think I might have folded.
Yes, maybe those with AuDHD, etc. understand better than the rest of us. But many of us, including armies of ADHD specialists and researchers, do understand. That’s why they make it their life’s work.
take care
Gina
