Recognizing ADHD in Women: Why So Many of Us Are Diagnosed Late

For years, I felt like something was off. I was overwhelmed, scattered, and constantly exhausted by trying to hold everything together—but I masked it well. Like many women, I was diagnosed with anxiety and depression, but something about those labels never fully explained what I was experiencing.

It wasn’t until I was 33 that I received my ADHD diagnosis. Thirty-three years old!

I’m Rachel Tenny, a Licensed Clinical Mental Health Counselor Supervisor (LCMHCS), and after working with hundreds of women who’ve felt the same, I now know this isn’t unusual. In fact, it’s extremely common.

Why Are So Many Women Diagnosed Late?

ADHD has long been misunderstood, especially when it comes to how it presents in girls and women. While the average age of ADHD diagnosis for males is 6–7 years old, for females, it’s 36–38. That’s a 30-year gap. Here’s why that happens:

1. ADHD Often Looks Different in Women

Girls and women are more likely to have inattentive ADHD, which doesn’t include the hyperactivity that many associate with the condition. Instead of being disruptive or impulsive, symptoms might show up as:

• Difficulty focusing

• Being labeled “spacey” or “daydreamy”

• Chronic forgetfulness

• Trouble following through on tasks

• Mental fatigue and disorganization

Because these symptoms are quieter, they’re often overlooked—or misattributed to other issues.

2. We Learn to Mask and Overcompensate

Many women with ADHD become masters of over-functioning. We build systems, write lists, double (or triple) check things, and stay up late trying to “catch up.” We appear successful or “on top of things” to others, but inside, we’re often anxious, overwhelmed, and burning out.

This ability to mask symptoms means that ADHD can go unnoticed—not just by others but even by ourselves.

3. We’re Often Misdiagnosed with Anxiety or Depression

It’s incredibly common for women with ADHD to receive anxiety or depression diagnoses first. While many of us do experience those conditions, it’s often the ADHD itself that’s fueling them. Imagine constantly missing details, struggling to complete tasks, and feeling behind—of course, anxiety and self-doubt will creep in.

Without understanding the root cause, it’s easy to feel like you’re failing at things that “shouldn’t be hard.”

4. Lack of Awareness in Adults Around Us

Teachers, parents, and even medical professionals have historically been less likely to identify ADHD in girls. Because the criteria have largely been based on studies of hyperactive boys, countless girls were told to “just focus” or “try harder” instead of being evaluated for ADHD.

You’re Not Alone—And You’re Not Too Late
