ADHD Symptoms in Girls: Why It Is So Often Missed, What It Looks Like and How It Is Diagnosed and Treated

Opening

"She's not naughty. She's just never on time, and she's always tired."

Riya was fifteen, a Class 10 student in Patna and, in her first years at school, a rather bright one. Her parents remember her as a "dreamy" child who would stare out of the window and lose her pencil case every week. Her teachers called her quiet and "not serious enough". In the last year, her marks had dropped, she had started crying before exams, and she was up past midnight rewriting the same notes. Her mother's first question to me was, "Is she lazy, or is she sick?" Neither word was right. Riya was working far harder than anyone could see, and her brain was working differently in ways that had been hidden for years.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition involving persistent patterns of inattention, hyperactivity and impulsivity that affect daily functioning across settings. It is one of the most studied conditions in child psychiatry. Yet for decades, most of that research and the everyday image of ADHD have been built around boys who are restless, loud and disruptive. Girls, who are more often inattentive and quieter, have been systematically missed. This article is about closing that gap, for the girls themselves and for the adults around them. If you would like the basics of the condition first, read the ADHD brain explained.

Two lenses, one condition

The boy in the room, the girl by the window

ADHD is the same condition in boys and girls. What differs is how it tends to show up. Clinicians describe two broad patterns: externalising (visible, active, disruptive) and internalising (inward, quiet, and often emotional). Girls are more likely to present with the inattentive pattern and to internalise their difficulties.

Why the difference matters

Teachers and parents often judge a quiet girl who is falling behind as careless or unmotivated. A boy who is disruptive is more likely to be noticed early. Research reviews published in recent years identify three main reasons girls are missed: adults have limited knowledge of how ADHD looks in girls, anxiety and mood problems overshadow the underlying ADHD, and masking hides the signs.⁶ The last of these is central, and we return to it below.

The numbers

A gap that narrows with age

In childhood, boys are diagnosed with ADHD far more often than girls. In population-based samples, the childhood ratio is roughly two boys to one girl; in clinical referrals, the gap is often much wider.³ In adulthood, the ratio narrows substantially, to somewhere between one-to-one and three-to-one in different studies. That pattern suggests the difference reflects in large part who is recognised and referred, not who has the condition.⁷

An outdated rule that kept girls out

For many years the diagnostic criteria required symptoms to start by age seven. Most inattentive girls, whose difficulties tend to become visible in the middle school years, did not meet that rule. The DSM-5 raised the age of onset to twelve in 2013, and clinicians now have more room to recognise ADHD in older children.¹ Adults who were missed as children may still be diagnosed, provided there is evidence of symptoms from childhood. What a late diagnosis can mean for a woman in her twenties or thirties is discussed in our research summary on adult ADHD, late diagnosis and burnout.

Masking

The hidden cost of looking fine

Masking means working very hard to appear to function normally: copying notes from a friend, rehearsing social scripts, double-checking every task, staying up late to catch up, or hiding the fact that you did not understand the lesson. It is a sensible response to school and family expectations, and for a time it works. A girl who masks may get good grades, which is precisely why her difficulties are overlooked. The cost, however, is hidden too.

What it often looks like first

Anxiety, low mood, and the ADHD underneath

Many girls first come to a doctor for anxiety, low mood, sleep trouble, eating difficulties or self-harm. Those problems are real and need treatment. But when ADHD sits underneath them, treating the surface alone often brings only partial relief. This is called diagnostic overshadowing: a more visible condition hides another.⁴ A careful assessment asks specifically about attention, organisation and impulsivity across childhood, not only about the current mood.

Hormones and attention

Some girls and women with ADHD notice that their symptoms worsen at certain points of the menstrual cycle, or around puberty, pregnancy and the menopause. Recent narrative reviews report changes in sleep, memory and attention around menstruation in some girls with ADHD. Hormonal fluctuation is therefore worth discussing with a clinician, particularly when a girl's symptoms seem to rise and fall in a cycle. It is not a reason to delay assessment.

The long way round

Many girls take the scenic route

Diagnosis is often delayed for years. Girls may see several doctors, be given counselling for anxiety, or be told to try harder, before someone asks the right questions. Adults who receive a diagnosis later often describe a sense of relief, and sometimes grief for the years of struggle. The route below is a composite of common experiences, not one person's story.

What helps the route be shorter

Assessment

A careful assessment, step by step

At the clinic, this work is done through the ADHD assessment service for children and adults, with a referral for a specific learning disability assessment when reading, writing or maths difficulties are suspected. For a girl under 18, the usual first step is a consultation with a child psychiatrist in Patna.

What the girl herself can bring

Treatment

What helps, and why more than one thing does

Treatment is tailored to the girl's age, symptoms, co-existing conditions, school situation and preferences. The most strongly supported approaches combine information and practical support with medicine where indicated.

The skills, routines and school supports that sit alongside or in place of medicine are described in managing ADHD without medication.

Your questions

Frequently Asked Questions

• Do girls get ADHD too?

  Yes. ADHD is common in girls and women, and it is a neurodevelopmental condition, not a character flaw. Girls are more often missed or diagnosed later, especially when they are quiet.

• Why was my daughter not diagnosed earlier?

  Many girls have the inattentive pattern, which is less disruptive. Anxiety and low mood may have been treated first. Diagnostic criteria and awareness were also more focused on boys for a long time.

• Is ADHD in girls the same as in boys?

  The core condition is the same, but the common presentation differs. Girls often show more inattention, emotional sensitivity and internalised distress, and their hyperactivity may be less visible.

• Can ADHD be confused with anxiety or depression?

  Yes, and they often coexist. A careful history from childhood helps separate them, and a clinician may treat more than one condition.

• Can hormones make ADHD worse?

  Some girls notice changes around the menstrual cycle, puberty, pregnancy or menopause. This is worth discussing with a clinician, and it should not delay assessment or treatment.

• Can ADHD be diagnosed in adults?

  Yes. Adults can be diagnosed if symptoms were present in childhood and continue to cause difficulties now. Evidence from school reports and family history is often important.

• Are ADHD medicines safe for girls?

  They can be, when prescribed and monitored by a doctor. Side effects and special situations, such as pregnancy, need individual review. Never self-medicate or share medicine.

• What can school do?

  Consider reasonable adjustments, a clear plan, regular feedback to parents, and an early referral for assessment where concerns persist. Focus on the pattern, not only on misbehaviour.
