ADHD symptoms in women and girls, and why they get missed
ADHD in girls and women often looks quieter than the familiar picture of a restless boy, so it is easier to overlook. Here is what it tends to look like, why diagnosis comes late, and what the research does and doesn't show.

In short
- ADHD in girls and women is more often the inattentive kind (distracted, disorganised, forgetful, daydreaming), which is easier to miss than hyperactivity.
- Girls are diagnosed later: in a New South Wales study of nearly 90,000 children, girls first used health services for ADHD at a median age of 13.6, against 9.4 for boys.
- Anxiety and depression are common alongside ADHD in women, and Australia's ADHD guideline warns they are sometimes diagnosed instead of it.
- Hormones may affect ADHD symptoms across the menstrual cycle, but the studies are few and small, and perimenopause has barely been researched.
- An adult assessment still has to establish that symptoms began in childhood and affect more than one part of life.
What ADHD often looks like in girls and women
The criteria for ADHD are the same for everyone. What differs is which symptoms show, and how easily other people notice them.
A 2020 expert consensus statement on females with ADHD notes that in community samples, girls are more likely than boys to have the inattentive presentation, which the authors describe as less obvious and therefore less likely to be detected. Healthdirect lists inattentive symptoms such as:
- starting tasks and not finishing them, or putting off anything that needs sustained effort
- being easily distracted, or daydreaming
- trouble remembering things, and losing things
- difficulty organising tasks, belongings or time
- careless mistakes and missed details
Girls and women can have hyperactive and impulsive symptoms too: fidgeting, talking non-stop, interrupting, reacting before thinking. ADHD in females is not only the quiet kind.
Two more things make ADHD harder to see. Internalising problems, meaning difficulties that turn inward such as anxiety, low mood and emotional distress, are reported more often in females with ADHD than in males. And girls may compensate by being compliant, socially adaptable and working hard to keep up, strategies the consensus statement says can mask or overshadow the underlying symptoms. It also suggests that difficulty regulating emotions may be more common or more severe in girls and women. If intense reactions to criticism are part of the picture, see our guide to rejection sensitive dysphoria.
Why girls are often diagnosed later
In childhood, far more boys than girls are diagnosed: the consensus statement reports clinical referral ratios from 3 to 1 up to 16 to 1, and about 3 to 1 in community samples. In adults, it says, the difference is more modest or absent.
Australia's national ADHD guideline asks clinicians to be aware that ADHD could be under-recognised in girls and women: they are less likely to be referred for assessment, more likely to have undiagnosed ADHD, and may be diagnosed with anxiety or depression instead.
The delay shows up in Australian data. A New South Wales study that followed 89,587 children from birth to about 18 found girls first used health services for ADHD at a median age of 13.6 years, against 9.4 for boys. A Stockholm register study of more than 85,000 people with ADHD found females were diagnosed about four years later than males on average.
Expectations play a part. The consensus statement cites research in which teachers given identical descriptions were more likely to refer a boy than a girl, and notes that parents may underestimate hyperactive symptoms in girls. A study of nearly 20,000 Swedish twins found girls were more likely to be diagnosed and treated when they also had hyperactive-impulsive or conduct problems, and concluded that girls without prominent outward problems may be more easily missed.
A late diagnosis doesn't mean the signs weren't there. In Welsh health records, girls diagnosed between 12 and 25 had already shown more health and educational difficulties in childhood than girls without ADHD, and by early adulthood had worse mental health, education and socioeconomic outcomes than girls diagnosed earlier. That is an association, not proof that earlier diagnosis would have changed things.
Anxiety, depression and other conditions alongside ADHD
Other conditions are common alongside ADHD, and in women they are often the ones noticed first. In the Stockholm study, 50.4% of females with ADHD had an anxiety disorder diagnosis and 37.5% a mood disorder diagnosis, roughly double the rates in males with ADHD (25.9% and 19.5%). Eating disorders and personality disorders were also recorded more often in females.
This cuts two ways: anxiety or depression can need treatment in their own right, and can also be what a clinician sees while the ADHD goes unrecognised. Healthdirect also lists learning difficulties, autism and sleep apnoea as conditions that can occur with ADHD. If autism may also fit, see what AuDHD means.
Parents of teenage girls should know about one finding. A US study followed 140 girls with ADHD and 88 without, from ages 6 to 12 into their late teens and early twenties. Among girls with the combined presentation, 22% reported at least one suicide attempt and 51% reported self-injury, compared with 6% and 19% of the comparison group. Rates in the inattentive group were lower (8% and 29%). It is one study from one region, but it is a reason to take distress seriously and to ask about it directly.
Hormones: periods, pregnancy and perimenopause
Research on ADHD and hormones is at an early stage. Here is where it stands.
- Menstrual cycle. A 2025 Australian systematic review found just 11 relevant studies, mostly small, with four rated unsatisfactory in quality. Together they suggest symptoms may worsen in the late luteal phase (the days before a period), and some studies reported ADHD medication working less well premenstrually.
- Pregnancy. The same review found a single study, which showed no significant difference in overall symptoms between women who continued, adjusted or stopped their medication. Decisions about medication in pregnancy belong with the prescribing doctor.
- Perimenopause and menopause. The review found no empirical studies of ADHD during menopause. A Dutch study of 209 women with ADHD found more severe menopausal symptoms, along with high rates of premenstrual dysphoric disorder symptoms and postpartum depression symptoms compared with general population figures. It relied on self-report and had no matched comparison group.
In short, hormonal changes may affect how ADHD symptoms feel, but there is not yet good evidence on how much, for whom, or what helps. An assessment still has to find that symptoms were present in childhood.
What an adult ADHD assessment looks at
Healthdirect summarises the criteria: symptoms that have lasted more than 6 months, were present before age 12, cause serious impairment in at least 2 settings (such as school, home or with friends), and interfere with daily functioning. ADHD can be diagnosed for the first time in adulthood, but it has to be established that symptoms began in childhood.
Australia's ADHD guideline says symptoms should be pervasive across two or more important settings, and that observations from more than one setting and more than one reporter should be used to confirm this. For an adult, that usually means looking at:
- your childhood, ideally with input from someone who knew you then, or old school reports if you have them
- how things are now at work or study, at home and in relationships
- standardised questionnaires, completed by you and sometimes by someone close to you
- other explanations, such as anxiety, depression, sleep problems or autism, and whether they sit alongside ADHD or explain the symptoms better
For a girl who coped through effort, childhood evidence can be subtle: report cards about not applying herself, homework that took hours. An assessment can conclude ADHD, not ADHD, or something else, and each is a useful answer. See how an ADHD assessment works.
If you are the parent of a teenage girl
- Look at the pattern, not single behaviours. Plenty of teenagers are disorganised. What matters is how many symptoms, how often, since when, and how much they get in the way.
- Ask the school what they see. ADHD has to show up in more than one setting, so a teacher's view is a normal part of assessing a child or teenager.
- Treat anxiety, low mood or self-harm as urgent in their own right, not as something to wait on until the ADHD question is settled.
- Your GP is a good first stop. Healthdirect notes that in children, ADHD is usually diagnosed by a paediatrician, child psychiatrist or child psychologist. More on child ADHD assessment.

Questions people ask
What are the signs of ADHD in women?
Common signs include trouble finishing tasks, losing and forgetting things, difficulty organising time, distractibility, and restlessness or impulsivity. In women these are often less visible and can sit alongside anxiety or low mood. For a diagnosis, symptoms need to have been present since childhood and to affect more than one part of life.
How do I know if I have ADHD as a woman?
Only a proper assessment can tell you. A useful first question is whether the difficulties go back to childhood and show up across settings, such as work and home, rather than only during a stressful period. Checklists and the free screener can suggest whether an assessment is worth it, but they cannot diagnose ADHD.
Why is ADHD missed in girls?
Girls more often have the inattentive presentation, which is less noticeable. They may compensate by working harder and following the rules, and their difficulties may be put down to anxiety or depression. Research also suggests teachers and parents can rate the same behaviour differently in girls and boys.
Can ADHD get worse during your period or perimenopause?
It may. A 2025 systematic review found early evidence that symptoms worsen in the days before a period, but it found only 11 small studies and none that looked directly at menopause. If your symptoms seem to change with your cycle, a simple diary can help you and your doctor see the pattern.
Can you be diagnosed with ADHD as an adult woman?
Yes. ADHD can be diagnosed for the first time in adulthood, and Australian and Swedish data show girls and women are, on average, diagnosed later than males. The assessment still has to establish that symptoms began in childhood, which is why information from family or old school reports helps.
