Women Wait Decades Longer Than Men for ADHD Diagnosis, Duke Researchers Say

Kate Jarvis was a straight-A student in the 1980s. She organized her backpack the night before school and prepped her toothbrush like clockwork. Then puberty hit, her grades slipped, and teachers started writing comments like "Kate has so much potential, if only she'd apply herself."

She wasn't diagnosed with ADHD until her late 30s. Before that, doctors told her she had anxiety and depression. Those diagnoses weren't wrong, exactly. They just weren't the whole story.

"It felt like character flaws rather than what it really was, which was undiagnosed ADHD," Jarvis told NPR.

The Research Gap Was Real

Julia Schechter, a clinical psychologist and co-director of the Duke Center for Girls and Women with ADHD, says Jarvis's experience is common, not rare. For decades, ADHD research focused almost entirely on boys, according to Schechter. That's not a conspiracy. It's a byproduct of how the disorder shows up.

Boys with ADHD tend toward the stereotype most people picture: hyperactive, impulsive, disruptive in class. Girls often don't look like that at all.

"They're more likely to appear distracted, disorganized, kind of have their head in the clouds rather than show that overt, hyperactive or impulsive behavior that can disrupt a classroom," Schechter told NPR.

A kid quietly staring out the window doesn't get sent to the school psychologist. A kid throwing chairs does. That's the blunt mechanical reason so many girls got skipped over for so long, and it's a fair criticism of how medicine built its diagnostic playbook around the loudest symptoms instead of the full range of them.

Misdiagnosed as Anxious or Depressed

Because the inattentive symptoms get missed, women often end up treated for something else entirely. Schechter says many are diagnosed with anxiety or depression instead, sometimes for years, without anyone addressing the ADHD underneath it.

"Sometimes those conditions are truly present," Schechter said. "Other times they're secondary to years of undiagnosed and untreated ADHD."

That distinction matters. Treating the anxiety without treating the ADHD driving it is like mopping the floor without fixing the leaky pipe. The symptom management might help a little, but the underlying condition keeps causing damage.

The Cost of Waiting Decades

This isn't just an academic diagnostic quibble. Schechter says the delay carries real consequences for women's lives.

Compared to girls and women without ADHD, those with the condition have more problems maintaining friendships, according to Schechter. They're more likely to experience abuse from romantic partners. And they're more likely to have a teen pregnancy compared to boys and men with ADHD, she says.

Those are not small outcomes. A neurodevelopmental condition that goes unaddressed until adulthood doesn't just cost a person some report-card comments. It shapes relationships, safety, and major life decisions during the years when those choices matter most.

What This Doesn't Prove, and What It Does

The claim isn't that every anxious or depressed woman actually has undiagnosed ADHD, and Schechter doesn't say that. She says ADHD is sometimes the hidden driver and sometimes a separate, co-occurring condition. Sorting out which is which requires an actual clinical evaluation, not a TikTok checklist or a gut feeling.

There's a legitimate concern: ADHD diagnoses in adults, and in women specifically, have risen sharply in recent years, and some clinicians and parents worry that greater awareness has tipped into overdiagnosis or self-diagnosis fueled by social media trends. That's a fair pushback to raise against any story pushing broader ADHD awareness. But it doesn't erase the specific, decades-old research gap Schechter describes, where diagnostic criteria were built around how the disorder shows up in boys and girls with quieter symptoms got filtered out of the system entirely. Those are two different problems, and both can be true at once: the historical underdiagnosis of women was real, and current diagnostic looseness is worth scrutinizing too.

What Comes Next

Jarvis says getting diagnosed in her late 30s felt like getting a name for something she'd wrestled with for 25 years. But she's clear that a diagnosis isn't a cure.

"Just because you know what something is, doesn't mean you can immediately fix it," she said. "And that's what I felt, like I needed to fix myself."

The Duke Center for Girls and Women with ADHD, where Schechter works, is among a small number of clinical programs built specifically around the idea that women's ADHD looks different and gets missed differently. Whether more medical schools and primary care training programs adopt that same framework, updating how doctors screen women who show up describing anxiety or feeling scattered, remains an open question. For now, the burden mostly falls on individual women to push for a fuller evaluation instead of accepting the first diagnosis offered.
