When ADHD in women is missed: the long road of misdiagnosis and misunderstood mental health
For many women and girls, ADHD was never even considered as a possibility.
Instead, they were diagnosed with anxiety, depression, bipolar disorder, or borderline personality disorder, and sometimes several of these over the course of their lives. With each new diagnosis came another treatment plan, another medication, and another round of trying to find something that might finally make everyday life feel more manageable.
For many, this led to years spent in a cycle of trial and error. Medications might help a little, or help for a while, but never quite touched the deeper problem. Therapies often made sense on paper, but still did not explain why life felt so exhausting, so overwhelming, and so much harder than it seemed to be for other people. It is not uncommon for women in this position to be described as particularly difficult to help, when in reality something fundamental is being missed.
Increasingly, we are beginning to understand that for many of these women, the missing piece was ADHD.
Why ADHD in women and girls is so often missed
When most people think of ADHD, they still picture a young boy who is hyperactive, disruptive, and unable to sit still. That stereotype has shaped both public understanding and clinical practice for decades. However, ADHD in girls and women often looks very different.
Many women develop highly internalised and masked presentations. They may appear outwardly capable, conscientious, and even high achieving, while privately struggling with chronic overwhelm, emotional intensity, exhaustion, anxiety, low self esteem, perfectionism, and a constant sense of having to work twice as hard just to keep up.
Because these struggles do not match the old stereotypes, ADHD is often not considered. Instead, the consequences of living with unsupported ADHD are what get labelled.
How ADHD gets mislabelled as other mental health conditions
When ADHD is not recognised, its effects are very easy to misunderstand.
Low mood and hopelessness can be diagnosed as depression, without recognising the years of burnout, failure experiences, and nervous system overload sitting underneath. Rejection Sensitivity Dysphoria, which involves intense emotional pain in response to perceived criticism or rejection, is also frequently mistaken for depression, particularly when someone describes feeling crushed, withdrawn, emotionally overwhelmed by everyday interactions or even suicidal.
PMDD, or premenstrual dysphoric disorder, adds another layer of complexity for many neurodivergent women. The severe, cyclical mood changes, irritability, despair, and emotional volatility that come with PMDD are often misdiagnosed as depression or, in some cases, even as borderline personality disorder, especially when clinicians do not join the dots between hormones, neurodivergence, and emotional regulation.
Emotional dysregulation linked to ADHD can be labelled as a personality disorder. Exhaustion, overload, and constant nervous system stress can be labelled as anxiety. Fluctuating energy, motivation, and emotional intensity can be labelled as bipolar disorder.
Sometimes, of course, these diagnoses are genuinely part of the picture. Mental health is complex, and people can absolutely have ADHD alongside depression, anxiety, trauma, or other conditions. However, for many women, these labels are describing the surface of the problem rather than the root cause.
The cost of years of being misunderstood
For many women, a later ADHD diagnosis is not about discovering something new. It is about finally understanding what has been there all along.
It is also often the moment when years of confusion start to make sense. Why so many medications never really worked. Why strategies that helped other people never quite stuck. Why life always felt harder than it “should” have done, despite being capable, intelligent, and trying so hard.
This is not about blaming individual clinicians. It is about recognising that our collective understanding of how ADHD presents in women and girls has been limited for a very long time, and that many people have lived with the consequences of that in the form of years, or even decades, of misunderstanding, inappropriate treatment, and deep self doubt.
Why this matters, especially in perimenopause
For many women, everything becomes even more difficult in their late thirties, forties, and fifties, when hormonal changes linked to perimenopause and menopause begin to interact with ADHD and emotional regulation, sleep, and stress tolerance can become even more challenging. At this point, the carefully constructed coping strategies that have held life together for years can start to fall apart, and the emotional and cognitive load can become overwhelming.
It is only now that ADHD and neurodivergence is becoming better understood and spoken about more widely that women finally start asking deeper questions about what is really going on.
A different, kinder narrative
Better awareness of ADHD in women and girls means fewer people spending decades believing they are broken, too much, or failing at life, when in reality their brain and nervous system were simply never being properly understood or supported.
For many, an ADHD diagnosis is not an ending. It is the beginning of a much more compassionate, coherent, and hopeful way of understanding themselves.
