The diagnosis that should have happened years ago
For decades, ADHD was studied almost entirely in boys. The diagnostic criteria were built on what ADHD looks like in young male bodies. Women and girls — who more often present with the quieter, inattentive form — were left out of the picture, and they are still being left out of it in clinical practice today. Many of the women I assess were told, as children, that they were just “sensitive,” “dreamy,” or “not as bright” as their peers. None of those things were true.
The historical and structural reasons ADHD in women gets missed
The research record here is unusually clear. Large reviews of clinical referral patterns, longitudinal population studies, and comparative prevalence data across two decades all point to the same conclusion: girls are diagnosed with ADHD at significantly lower rates than boys in childhood, and women are diagnosed at significantly lower rates than men across adulthood — and those gaps are not because ADHD is rarer in women. They are because ADHD in women is less visible.
The reasons are well-documented:
Girls with ADHD are more likely to present with the predominantly inattentive presentation — not the hyperactive-impulsive one. Inattentive ADHD does not cause teachers to call parents in for meetings. It does not show up as disruption. It shows up as a child who daydreams through class, loses her homework, blends into the background, and slowly falls behind in silence.
Girls learn to mask. From early childhood, girls are socialised toward self-monitoring, social harmony, and suppression of disruptive behaviour. A girl with ADHD who has the internal experience of an ADHD boy often does not externalise it the same way. She puts her energy into compensation: over-preparing, re-reading, people-pleasing, perfectionism. The cost of this compensation — chronic anxiety, exhaustion, burnout, disordered eating patterns in some cases — is often the thing that eventually brings her in for help, long after the ADHD was there.
The diagnostic criteria in the DSM were built on samples of young boys. They are designed to capture what ADHD looks like in that population. A quieter, internally-hyperactive, anxiously over-compensating eleven-year-old girl can meet full criteria and still not look like the textbook picture a pediatrician or GP is holding in their head.
And — in Singapore specifically — a strong academic culture rewards the exact coping strategies (rigid routines, over-studying, perfectionism) that let girls with ADHD function at high cost. This further delays recognition.
What to look for in girls
The picture in girls often looks different from the picture in boys. Some patterns I watch for:
A child who is quiet but disorganised — loses forms, can’t find her bag, forgets instructions, takes a long time to start homework.
A child who has strong verbal ability and is underperforming academically in ways that don’t match her obvious intelligence.
A child whose homework takes two to three times longer than it should, with tears or shutdowns at the end of the day.
A child whose emotional regulation is fragile — big reactions to what seem like small things, sensitive to criticism, frequent overwhelm.
A child who is socially sensitive, socially conscientious, and sometimes socially anxious — worrying about being liked, replaying conversations, ruminating over perceived missteps.
A child who is developing — or has already developed — anxiety, perfectionism, or disordered eating patterns as part of the compensation strategy for an undiagnosed underlying difference.
A child whose older relatives (mother, aunts, grandmothers) have a family history of attention, mood, or anxiety difficulties.
None of these, in isolation, is diagnostic. All of them together often points somewhere. Assessment is the way to get clear. In girls, the clinical task is frequently to untangle inattentive ADHD from generalised anxiety, from perfectionism, from early mood symptoms, and — not uncommonly — to find that several of these are genuinely present and interacting.
What to look for in adult women
By adulthood, the compensation patterns that girls develop have usually become invisible to everyone except the woman living inside them. The woman’s external life often looks organised. Her internal life is a different story.
Some of what I hear repeatedly:
“I can do complex work, but I can’t file a routine form.” “My house looks fine because I spend an hour a day compensating for what would otherwise be chaos.” “I cry after meetings that nobody else seems to have found hard.” “I am either over-prepared or I am avoiding.” “I’ve been in therapy for anxiety for ten years and something about it never quite worked.”
The classic adult-ADHD features — executive function failure, time blindness, working memory gaps, emotional reactivity, rejection sensitivity — are all present. They are often accompanied by a long history of anxiety, sometimes by depression, and sometimes by disordered eating or perfectionism that began in adolescence.
Hormonal interactions are well-studied and often clinically relevant. Estrogen plays a role in dopaminergic signalling, which is part of why many women notice:
ADHD symptoms worsening in the premenstrual phase — often meeting criteria for premenstrual dysphoric disorder on top of the ADHD.
ADHD symptoms shifting across pregnancy and especially in the postpartum period.
A significant worsening of ADHD symptoms in perimenopause and early menopause, sometimes for the first time in a woman’s life — or, more commonly, surfacing the underlying ADHD that had always been compensated for.
Treating adult ADHD in women often requires attention to these interactions, and — where relevant — close coordination with a gynaecologist or psychiatrist who understands them.
Assessment — with an eye to what has been missed
My approach to assessing women and girls for ADHD uses the same multi-method standard I use for any ADHD assessment, with particular attention to the ways inattentive ADHD, anxiety, perfectionism, and trauma can look similar on the surface but require very different treatment.
For girls, this means careful developmental history, parent input, school input where relevant, standardised scales in both parent and self-report versions, and — critically — retrospective scrutiny of the pattern from early childhood. I spend time looking at whether the anxiety or perfectionism has grown on top of a pre-existing attention difference, or whether the attention difference is being caused or amplified by anxiety.
For women, retrospective history is often the most important part of the assessment. I ask about childhood in detail — school reports, memories of homework, teacher feedback, early friendships, how you were described as a child. I ask about the hormonal history — adolescence, pregnancies if relevant, postpartum experiences, current cycle. I ask about what has changed recently, because perimenopause in particular can surface the question for the first time.
I also screen carefully for the co-occurring conditions most common in this population — anxiety, mood, disordered eating, and complex trauma — because treatment sequencing depends on what else is there and how the pieces interact.
Treatment — ADHD, the anxiety and mood that have grown with it, and the practical scaffolding
The evidence-based treatments for adult ADHD apply here — cognitive-behavioural therapy adapted for ADHD, medication consultation with a psychiatrist where appropriate, and executive function scaffolding. Two things I pay particular attention to with women:
Un-bundling the ADHD from what grew on top. A woman coming in for an ADHD consultation is often carrying two decades or more of anxiety, self-criticism, and perfectionism that developed as compensation. Part of the work is treating the ADHD with evidence-based protocols, and part of the work is loosening the unhelpful meta-story — the internal narrative that every struggle is evidence of personal inadequacy rather than evidence of an underlying condition that has been doing its job, invisibly, for thirty or forty years.
Co-occurring anxiety, OCD, mood, and disordered eating. These are my primary specialty areas, and I treat them with the protocols that have the strongest evidence base. For anxiety and OCD, that’s exposure-based cognitive-behavioural therapy — the model I trained in under Dr. Stephen Whiteside at Mayo Clinic and under some of the core researchers in the field. For mood, that’s the cognitive and behavioural protocols developed by Dr. Lauren Alloy and Dr. Eric Youngstrom, under whom I trained directly.
Medication consultation, if indicated. I don’t prescribe. I refer to psychiatrists in Singapore I know and trust — and with women specifically, to psychiatrists who understand how ADHD medication interacts with hormonal cycles, pregnancy, breastfeeding, and perimenopause. That information matters, and a clinician who does not have it should not be making those decisions.
Next steps
Request a consult and we’ll set up a 15-minute call. Many of the women I see have been carrying a long-standing sense that something didn’t fit — a therapy that didn’t quite work, a medication that didn’t quite help, a childhood story that never felt complete. We’ll start there. If you want to read more first, the adult ADHD page covers the adult presentation in more general terms, and the pillar page on ADHD and neurodiversity maps the whole lifespan.
