The Trauma of Adult Undiagnosed ADHD
How ADHD affects adults, and what they can do about it.
In the past couple of years I’ve heard from at least four friends about their ADHD diagnosis. The story is almost always the same, or at least very similar.
“Dude!” they write to me. (Okay, that’s what the male friends say—but the rest of the story is the same.)
“You’ll never guess what happened. I got diagnosed with ADHD.”
“Oh wow!” I say. “Good for you, I’m glad you’re getting some help.”
Then they mention something about Adderall or another ADHD medication, and I say, “You know I’ve been taking Adderall off-and-on for eight years, right? I’ve written a lot about it on the blog, and we’ve probably even talked about it sometime.”
And then they say … “I had no idea! I wish I’d known sooner.”
To be fair, I know people don’t read stuff they’re subscribed to, and even good friends lose track of conversations. But also, this is classic ADHD: you hyperfocus in some areas and ignore others. Sometimes, you miss key information that could help you.
This is what happens to lots of people, not just my friends. Millions? I have no idea. One estimate has it at something like 4-5% of the adult population. It could even be higher, since many adults never seek help for their symptoms, or they could be misdiagnosed with other conditions.
But again, the key point: many adults have untreated, undiagnosed ADHD—and it affects many parts of their lives, to varying degrees.
My four friends are all better off from having joined the ADHD club.
Maybe That’s You? Or Maybe You Know Someone?
I tell this story because YOU probably know someone who could benefit from an ADHD diagnosis. Since I started sharing on this topic, people have been coming out of the woodwork from all over. Maybe it pertains to you personally—but even if not, like I said, I bet you know someone.
I’ve also heard from people who say that learning more about ADHD has helped them understand their kids, their partner, or another loved one better.
Speaking of kids/teens/young people, in general they have it hard these days in lots of ways. They’re growing up in a vastly different world than any previous generation. The list of challenges is long!
But at least one thing is better for kids now: ADHD, as well as other neurodivergent conditions, is much less of a stigma, and much more likely to be diagnosed.
If anything, kids these days (especially younger ones) might be overdiagnosed with ADHD these days. But if the pendulum has swung too far in recent years, it still points to a problem for everyone who once was a kid and didn’t get help they needed.
That’s what this post is about.
How ADHD Affects Adults
I’m not going to write a “You might have ADHD if…” post. Not all difficulty with focus or attention is ADHD. There are distractions and challenges everywhere these days, you know?
If you really do think you might have ADHD, I recommend getting an evaluation done if at all possible. (More on this in the next section.) Either way, though, you can gain some understanding that may help you to live better.
It’s not a checklist, but ADHD is something to consider if you’ve had some of the problems below.
Executive Functioning Issues
Adults with ADHD often struggle with executive functions, including:
Task initiation (getting started without long delays)
Attention regulation (staying focused on a specific task)
Working memory (your brain's notepad, where it briefly holds and works with info you need right now)
Planning & prioritization (figuring out what needs to be done first and mapping out how to do it)
Impulse control (your brain's ability to stop you from making hasty decisions or actions without thinking about the consequences)
Emotional regulation (how you control your feelings, like not letting anger or sadness take over, so you can react to things in a calm and collected way)
Organization (keeping your things and thoughts in order to smoothly navigate your tasks)
Time blindness is another huge problem for many of us, including me. It’s a condition where you chronically under- or over-estimate the amount of time required for something. It also refers to a challenge of keeping up with time in general.
Social and Relationship Impacts
In addition to executive function challenges, adults with ADHD can also experience difficulty in relationships, careers, and overall wellbeing. This includes:
A higher likelihood of dropping out of high school or college (fun fact, I was a high school dropout, though I later went to college and then graduate school)
Frequent job changes or periods of unemployment, often due to misaligned job roles (it’s no secret that many people with ADHD are self-employed, because traditional roles don’t work well for them)
Difficulty with social cues and maintaining attention in social situations (sensitivity can be a gift! but it’s complicated)
A higher risk for other mental health conditions, including anxiety, depression, and substance abuse, often as a coping mechanism or due to chronic stress from unmanaged ADHD symptoms
Risky or maladaptive behaviors, partly due to impulsivity and seeking stimulation (substance abuse, gambling, unhealthy relationships, etc.)
The list could go on! And to be clear, there are some real strengths and good things about ADHD, including the ability to hyper focus on tasks you’re excited about, as well as increased creativity.
In fact, if you asked me today “Would you give up ADHD?” as in, would I prefer to have lived my life as neurotypical—I’d say no thanks. I’m grateful for the different perspective and life experience I’ve developed, normal or otherwise.
But this post is about the trauma of undiagnosed ADHD. If you live your life without understanding a key part of you, you’re not able to compensate for the weaknesses while maximizing your strengths. And that really is a trauma!
One more important thing before we go on…
Childhood ADHD tends to show up differently in girls than boys.
This post is about adult ADHD, but let’s note one important detail that may affect at least half the people who read it. I’m not sure if it’s still the same, but historically at least, boys were diagnosed with ADHD much more than girls, in large part because of behavioral differences.
Hyperactivity does not always mean physically acting out. It can also refer to hyperactivity of the mind.
I’ve thought about this a good bit as I’ve considered my own experience. I too was someone who daydreamed a lot and had a rich inner world, sometimes to the exclusion of wanting to be involved socially. I had difficulties paying attention and staying on task.
But I also had significant behavioral issues (oppositional defiant disorder, as the DSM categorizes it).1 If I’d been a girl, or if I simply hadn’t exhibited those behaviors, I might never have been diagnosed with ADHD. Then I’d be reading someone else’s post about ADHD and thinking, hmmm, I wonder if that’s me!
(Side note: I also recommend the work of
, who hosts the largest online community of women with ADHD.)Alright, on to some action points…
Two Things You Can Do
First, speak to a mental health professional about getting an evaluation. If you’re able to talk with a doctor and go through an evaluation, no doubt you’ll learn something—even if you don’t emerge with an ADHD diagnosis. And if you do get diagnosed, of course, presumably you’ll qualify for a prescription for medication, should you choose to go that route.
There are also a few online companies that offer evaluation and diagnosis now. I’m not going to link to any because I don’t know much about them and want to be careful about any implied endorsement.
Still, if I was trying to figure myself out and didn’t have access to a proper healthcare network, I’d probably seek out one of these options. One advantage, in addition to accessibility, is that these providers specialize in ADHD and are therefore less likely to be skeptical or unfamiliar with it.
Since I’m not one of those professionals, I’ll focus more on the self-education part—which is also important. The weird thing is that even after I resumed caring for my ADHD as an adult, I wasn’t really given any information about it. I had a prescription, and that was helpful, but it was incomplete.
Even though I do use medication, learning when and how to take it is at least as important as the meds themselves. See my very detailed post on how I use—and don’t use—Adderall to focus.
One thing I didn’t say in that post: three years into taking Adderall, I’m not sure I could even define what an executive function was—I just knew I struggled!
It’s only been in recent years that I’ve actually set out to learn more about neurodivergent conditions, and that’s been very helpful as well.
In other words: there’s room for both medical treatment and self-education. And at least for some of us, both are essential.
Resources and Experts
There’s a big community of experts on most social platforms, especially YouTube, TikTok, and Instagram. I don’t think you should get all your information from social posts, of course—but it can be a good supplement to actual medical care.
Also, the list below isn’t meant to be exhaustive (feel free to add to it in the comments!). It’s mostly people I know personally or am familiar with.
Dr. Tracey Marks - an Atlanta psychiatrist publishing weekly YouTube videos to more than 1.5 million subscribers
Dr. Edward Hallowell - a pioneer in the field of adult ADHD, his work focuses on the positive aspects of ADHD and how to harness them
Russell Barkley - a retired Professor of Psychiatry and Neurology who has written several books on adult ADHD
Dani Donovan - creator of ADHD Comics, an Anti-Planner, and more
Jessica McCabe - The creator of How to ADHD, a YouTube channel dedicated to educating people about ADHD
Rene Brooks - founder of Black Girl, Lost Keys, a blog that offers a perspective on ADHD, particularly focusing on the experiences of women of color
Nicole Bulsara - offering group coaching programs based on the work of Dr. Kristin Neff
I’ve also found these books helpful: Brain Hacks, Executive Functioning Workbook for Adults, and Extra Focus (an especially well-titled book by Jesse J. Anderson)
Conclusion
I know that this post isn’t for everyone, but I also know that a lot of people need it—so if you’re in that club, I hope it’s helpful. 🙂
Feel free to share in the comments if you have an experience of your own, and anyone can share the post so that other people can benefit.
Conversation Starters
Do you have any experience with ADHD (either diagnosed or undiagnosed)?
What’s something you know now but wish you understood sooner?
How many browser tabs do you have open right now?
I had a fourth topic but then I went to do something else and forgot.
Depending on who you ask, oppositional defiant disorder can be kind of an old-school diagnosis. One argument is that it risks pathologizing behaviors that might be considered developmentally appropriate, or even generally appropriate to abnormal situations.
OK - so first, let me say that I say “Dude” all the time. (Usually more like Duuuude), and I’m a 65 year old female 😁).
As for the ADHD - I was diagnosed about 4 or 5 months ago (that whole timey -wimey thing). I take Vyvanse and, cliche or otherwise, it has literally changed my life. I get up, I get sh*t done, I can follow directions, I don’t finish people’s sentences (as often), and I’m so damn happy in my own skin. I won’t go into a whole long thing about the changes in my life, but really liking myself (finally) is flat-out amazing.
I was diagnosed about 2 years ago, right when I turned 40. I've spent these last couple years mourning the loss of a life I think I could have lived if I had understood myself better when I was in my early 20s and making big life decisions. I wasted so much time hating myself because I struggled to fit into a more conventional way of life and I could never understand why I was always so unhappy. My brother died by suicide last June. He had bipolar disorder but I believe he also had undiagnosed ADHD. We had many of the same worries about life and talked about them often. I think it was a major contributing factor in his suicide. Now I feel more urgency to really live on my own terms, not just for myself, but to honor him.
