I know that sounds shocking, especially coming from me—someone who has spent her career assessing, diagnosing, and treating ADHD. But hear me out.

The way ADHD is currently defined and categorized in the DSM (Diagnostic and Statistical Manual of Mental Disorders) does more harm than good. It’s outdated, oversimplified, and it fundamentally misses what ADHD actually is.

The Problem With the DSM

The DSM reduces ADHD to a checklist of behaviors: forgetful, fidgety, impulsive, distracted. It slices ADHD into three “presentations”—inattentive, hyperactive-impulsive, combined—as if we’re describing three different conditions.

But none of this gets at the root of ADHD.

Because ADHD isn’t a disorder of attention. It’s not even about activity levels. It’s a self-regulation condition—of attention, emotion, behavior, motivation, sleep, appetite, and energy.

And the DSM isn’t built to capture that. It was built to categorize observable symptoms, not lived experiences or neurodevelopmental realities. Which means ADHD, as it actually operates in the brain, gets flattened into a behavioral stereotype.

Why This Matters

When ADHD is treated like a set of behaviors, people—especially women—get missed.

• If you’re not bouncing off the walls, you’re told you “can’t” have ADHD.
• If your hyperactivity is internal—what Dr. Russell Barkley calls “a busying of one’s mind”—you’re told you’re anxious or depressed.
• If your emotional dysregulation is intense, you might get labeled bipolar.
• If your struggles show up in work, relationships, or food, you’ll be told it’s stress, burnout, or lack of willpower.

I lived that. My clients live that. And it all comes back to the fact that the DSM doesn’t frame ADHD as what it really is.

ADHD Is Not a Mental Illness

Here’s the bold part: ADHD doesn’t even belong in the DSM because it’s not a “mental disorder” in the traditional sense. It’s a neurodevelopmental condition.

Brains with ADHD develop differently in the circuits that regulate attention, inhibition, motivation, and emotion. That’s not pathology—it’s variation. And variation requires support, not stigma.

By putting ADHD in the DSM, we’ve medicalized difference. We’ve taught generations of people to see themselves as broken instead of as humans with unique brains who need different strategies.

A Client’s Story

A client of mine—we’ll call her Julia—came to me after years of failed treatments for depression and anxiety. She said, “I just don’t get it. Why can’t I do the things other people do so easily?”

The answer wasn’t depression or anxiety. It was ADHD. But not the ADHD of the DSM checklist. Not “forgetful, fidgety, disorganized.”

Her ADHD showed up as emotional flooding, perfectionism, poor sleep, and a restless brain that never turned off. She was dysregulated—internally, invisibly.

And once we named it as ADHD—not a mood disorder, not a character flaw—everything shifted. Julia didn’t feel broken anymore. She felt understood.

Rethinking ADHD

Imagine if ADHD wasn’t in the DSM at all. Imagine if, instead of being defined by a list of “symptoms,” it was defined as what it really is: a regulation condition of the brain.

• No more splitting it into “presentations” that don’t reflect reality.
• No more pathologizing people into boxes that don’t fit.
• No more missing women, girls, and adults whose ADHD is invisible.

Instead, we’d look at ADHD as a spectrum of self-regulation differences that affect performance, relationships, and wellbeing. And we’d treat it accordingly—with medication when needed, yes, but also with strategies, education, coaching, and compassion.

Why I’m Saying This Out Loud

Because as long as ADHD lives in the DSM, it will keep being misunderstood, minimized, and mislabeled. We’ll keep fighting over whether it’s real, instead of focusing on what helps.

It’s real. It’s lifelong. It’s not rare. And it’s not a “disorder of attention”—it’s a condition of regulation.

So maybe the most radical, helpful thing we could do is take ADHD out of the DSM entirely—and finally start treating it for what it is.
