“Why Wasn’t I Diagnosed Sooner?”: The Hidden Presentation of ADHD in Women & AFAB People

Let’s talk about something I have heard almost daily in my practice for the past five years:

“I didn’t even consider ADHD until my 30s… and now I can’t unsee it. It is EVERYWHERE.”

Or:

“I was an overachiever. I got good grades, did all the clubs, and never got in trouble. I wasn’t hyper. How did everyone miss this?”

Getting a diagnosis can be a relief, but it can also bring up lots of other emotions. You might feel sad, confused, or even angry that you didn't figure it out sooner. When people finally realize they have ADHD, it's not just a simple "oh, I get it now" moment. It's more like the pieces of a puzzle finally falling into place, and suddenly you see yourself in a whole new light. Things that were fuzzy or confounding before become clear, and you start to understand why you are the way you are. It's like getting a new picture of yourself, one that makes sense of all the things that didn't add up before.

Here's the truth: ADHD in women and people assigned female at birth (AFAB) has been underdiagnosed and misunderstood since ADHD and its diagnostic predecessors were even a thing. This isn't because it's rare or mild, but because it doesn't always show up in the ways we've been taught to look for it. We need to start by acknowledging this fact and by being more aware of the different ways ADHD can affect women and AFAB people.

ADHD Was Never Designed With You in Mind

To really understand why a lot of people are diagnosed with ADHD later in life, we need to look at how the condition has been understood. Most of the criteria used to diagnose ADHD, as well as the early research and clinical models, (shockingly) were based on studies of young boys - specifically white boys who were hyperactive and acted out. These were the kids who were sent to get help, who were studied, and who ended up shaping the way we think about ADHD. As a result, the system was pretty much designed around them.

The traditional characteristics of ADHD is that it's someone who can't sit still, is always interrupting, and has a hard time following rules in places like school or work. But what if your ADHD doesn't look like that? Maybe you're not the type to run around, blurting out answers or getting into trouble all the time (or maybe you’ve been taught to sit on your hands). If that's the case, it's possible that people might not even think you have ADHD, and that's a problem. The folks in charge might not look beyond the surface to see what's really going on.

Lots of AFAB folks have a different experience with ADHD. Instead of being hyperactive, they might be inattentive. They often struggle internally with feelings and thoughts that are hard to manage, rather than acting out in obvious ways. These individuals might feel completely disorganized or overwhelmed, have trouble focusing, or feel like their emotions are all over the place. But because they're not necessarily causing a disturbance, they can easily go unnoticed. And when someone's behavior doesn't disrupt the people and things around them, it's common for their struggles to be overlooked. This can make it really tough for them to get the help and support they need.

The “Quiet ADHD” That Gets Overlooked

A pattern emerges when we listen closely to these stories. Many people describe themselves as struggling in ways that were easily overlooked - or attributed to personal or parental failings rather than an executive functioning issue.

These kids weren't the ones acting out or causing trouble - they were the ones who would often zone out, staring out the window, lost in thought; they often would have vivid and intricate inner worlds. These folks might forget their homework or put off starting an assignment until midnight on the night before it’s due. And even though they felt like they were always playing catch-up, they tried to deal with it on their own, quietly struggling to keep up.

These kids weren't seen as having a real problem that needed to be addressed. Instead, people used nicer words to describe them, like "spacey", "sensitive", or "emotional". Some were even misdiagnosed with anxiety and/or depression. They were often reminded that they had a lot of potential, but just needed to try harder, focus more, or apply themselves better. The thing is, these messages weren’t always helpful or supportive. Much of the time, they made these kids feel like there was something wrong with them, like they just needed to be better or do better to fit in. It's like they were being told that if they could just change who they were or how they behaved, everything would be okay.

When people struggle with internal issues, it can be really tough to notice (this is called internalizing symptoms). Instead of causing trouble for others, they might be too hard on themselves or get stuck in their own thoughts. This can lead to problems like overthinking, rumination, avoiding things, shutting down, perfectionism, or being overly critical of themselves. This is a double-edged sword because some of these symptoms - like perfectionism and over-functioning - often are exemplified by our Boot Straps culture and ALSO because the internal symptoms like rumination and avoidance are internal and therefore invisible.

Masking: The Survival Strategy No One Sees

Layered on top of this is something that doesn’t always show up in diagnostic manuals but is deeply present in lived experience: masking.

Masking is the process of suppressing or compensating for neurodivergent traits in order to meet social expectations.

For a lot of girls and AFAB people, this journey starts really early on, and it can happen without them even realizing it. From a young age, girls are often taught to be nice, organized, and in tune with others' emotions – even if that doesn't always feel natural to them. This can lead to a sense of disconnection between how they're expected to be and how they actually feel inside.

So they learn to override their needs. They sit still even when their body feels restless. They make eye contact and practice small talk, even if it’s physically painful. They rehearse conversations in their heads to avoid saying the wrong thing. They over-prepare, overcompensate, and over-function—not because it comes naturally, but because the alternative (not fitting in) feels unsafe.

This is especially prevalent during adolescence, when the entire developmental goal is fit in. 

Over time, hiding your true self can create a strong illusion that everything is okay. To others, your life may seem perfect or even inspiring, but in reality, it's draining. You put on a mask to hide your struggles, and it can be exhausting to keep up the act. On the surface, everything looks fine, but beneath the mask, you're tired of pretending – and resentful that you have to.

People often describe their experiences in a way that doctors don't always catch. For instance, someone might say, "I had to create a whole personality just to avoid getting in trouble," or "I wasn't disorganized, I was just really tired from trying so hard to stay on top of things." These aren't exaggerations - they're real expressions of what it's like to have a nervous system that's constantly working extra hard to cope with a world that doesn't always understand or support it. This can be really overwhelming, and it's not just about being "disorganized" or "troubled,” it's about being exhausted from trying to fit into a system that doesn't always accommodate your needs.

Hiding your true self can work for a little while, but it's not a sustainable long-term solution. Inevitably, long-term masking leads to feeling exhausted, anxious, and unsure of who you really are. It can also make you feel disconnected from the person you're meant to be.

The Emotional Cost of Being Misunderstood

When ADHD goes undiagnosed, the impact is not limited to missed treatment, skills, or support. Missed diagnosis shapes the narrative a person develops about themself.

Instead of understanding their experiences as neurobiological differences, many people internalize these struggles as personal failures.

Difficulty with follow-through becomes laziness.

Emotional intensity becomes being “too much.”

Inconsistency becomes a lack of discipline or unreliability.

Over time, this constant narrative and a social economic system that has a moral value system that prioritizes efficiency over humanity cements those negative terms into low self worth and poor self esteem.

We often see people struggling with feelings of not being good enough, which can lead to perfectionism and a deep-seated fear of rejection. They might push themselves too hard, not because it's helpful, but because they feel like they need to make up for something that's wrong with them. This can put their nervous system on high alert, always trying to avoid failure or criticism, and never feeling like they're doing enough. It's like they're constantly running on a treadmill, trying to outrun their fears and doubts - and the criticism of others, but never really getting anywhere. This can be really tough to deal with, and it's not uncommon for people to feel stuck in this cycle of self-doubt and anxiety. Get stuck for too long, and this is where we find ourselves in burnout.

Studies have found that when ADHD goes undiagnosed in women, it can lead to a range of serious challenges, including anxiety, depression, eating disorders, and trouble managing emotions. These issues aren't separate from ADHD - they're often the result of living with a condition that isn't well understood or supported, especially in systems that aren't designed to help women or AFAB folks succeed. This, then, can lead to a lifetime of struggles, as women with undiagnosed ADHD try to cope with a brain that works differently, without the right tools or support. As a result, they may face higher risks of anxiety, depression, and other mental health challenges, simply because their ADHD has been overlooked or misunderstood.

Hormones, Cycles, and the Missing Conversation

Another critical piece of this conversation—and one that is still underrepresented in both research and clinical practice—is the role of the menstrual cycle and hormones.

For women and AFAB people with ADHD, hormone changes can have a huge impact on their symptoms. This is because estrogen plays a key role in regulating dopamine, a chemical in the brain that affects behavior and mood. 

As estrogen levels go up and down throughout the menstrual cycle, ADHD symptoms can get worse or better. Some women notice that their symptoms get more intense during the luteal phase, when estrogen levels drop. This can mean feeling extremely tired, having brain fog, and acting on impulse more often. These impulses can sometimes lead to behaviors that give a quick feeling of excitement or pleasure, but might not be the best choice in the long run (do you doom scroll or impulse buy more?). Additionally, many women with ADHD report that their symptoms change during times of big hormone shifts, like after giving birth or when they're going through perimenopause.

Without an understanding of this chemical interaction, these changes can feel confusing or even alarming. People often assume their ADHD is “getting worse,” when in reality, their neurobiology is responding to hormonal shifts in predictable ways.

Even with more research being done, many models for diagnosing and treating ADHD still don't consider how symptoms can change. Because of this, people assigned female at birth might not get diagnosed as often as they should; and even when they are, their treatment might not be right or might not change when their symptoms do.

When ADHD Looks Like “Just Life Being Hard”

ADHD can be tough to spot because it often gets mixed up with the normal challenges of daily life. This is especially true for women who are juggling a lot of responsibilities, like taking care of their partner, kids, and career, as well as managing their extended family. As women take on more roles, it can be hard to tell what's causing their stress and struggles - is it just the demands of everyday life, or is it something more, like ADHD?

ADHD can be tricky to spot, and it doesn't always look like you'd expect. Sometimes, it can seem like you're just really good at procrastinating, or that you have a hard time getting started on things,  or that you’re most productive when you’re spinning several plates at once. Other times, it can look like you're a total workaholic, but then you burn out and can't do anything for a while. In relationships, ADHD can make you overthink everything, or react really strongly to things that might not seem like a big deal to others. You might also have trouble setting boundaries, or saying no to people. And at home, ADHD can make it hard to keep things tidy, or stick to a routine. You might feel like everything is just a little bit harder than it should be, and it can be really frustrating when all those tiny “imperfections” accumulate.

For women and AFAB folks, living with ADHD can be tough enough when they're single. But when you add more stress, responsibilities, and stimuli to the mix - especially in a society that often favors men - the symptoms can become even more intense and frequent. It's like the challenges of everyday life can exacerbate the struggles of ADHD, making it harder to manage and cope.

It's easy to brush off certain challenges as just being part of someone's personality or a result of stress and life circumstances. But when these patterns keep happening, are really disruptive, and start to affect daily life, it's clear that something more is going on. These issues aren't unique to ADHD, but when they're persistent and really impactful, they need to be taken seriously and not just dismissed as a personality trait.

The real issue isn't about ignoring the challenges people face, but rather about figuring out what's actually causing them. We need to get to the root of the problem to truly understand what's going on.

Late Diagnosis: Relief and Grief, Side by Side

When people are finally diagnosed, it is rarely a simple moment of clarity. More often, it is a layered and complicated experience that includes both relief and grief.

Getting a diagnosis can be a huge relief. It's like finally having a name for what you're going through. Suddenly, things that seemed crazy or confusing start to make sense. You can put into words what you've been feeling, and that's a powerful thing. A lot of people say that this is the first time they've really understood themselves, and it's a kind of understanding that's full of kindness and compassion. It's like a weight has been lifted off your shoulders, and you can see your whole life in a new light. Everything that happened before starts to fall into place, and it's like you're looking at yourself and your experiences for the first time.

Grief, however, often follows closely behind. There is a recognition of what was missed, what was misunderstood, and what might have been different with earlier support. There can be anger toward systems, caregivers, or even yourself for not recognizing the symptoms and taking action sooner.

Both of these responses are valid. Both deserve space.

Moving Forward With Understanding, Not Shame

If you're reading this and seeing parts of yourself in these patterns, don't jump to conclusions just yet. Instead, try to be curious and ask yourself some questions.

What are these patterns, and how are they affecting your life? 

Take a step back, breathe, and let's explore this together.

Take a closer look at the things that always seem to be a struggle and the things that surprisingly come easily. Think about the ways you've already found to cope, even if they're not perfect. These aren't signs that you're not doing well - they're signs that you're finding ways to adapt and make things work.

Getting a good understanding of what's going on can be really helpful, especially when you talk to practitioners who know a lot about ADHD and how it affects women andAFAB people. It's not just about being hyperactive, it's about understanding how ADHD works in different people. Also, it's really important to let go of feelings of shame and guilt. Instead of thinking "why can't I do this?", try thinking "what do I need to do to make this work for me?" - it's a big change, but it can make a big difference. It's about being kind to yourself and figuring out what you need to succeed, rather than beating yourself up over what you can't do.

Support does not come from forcing yourself into systems that do not work. It comes from building systems that align with how your brain actually functions.

A Final Thought

You didn't do anything wrong, and you were always enough, just as you were. The problem was that the system you were in didn't understand what you were going through, and it didn't have the right words or ways to support you. It wasn't flexible enough to see things from your perspective, and that's what made it so tough for you to navigate.

Now, with more information and more nuanced understanding, there is an opportunity to approach yourself differently. Not as a problem to be fixed, but as a person whose brain deserves to be understood, nurtured, and supported.
