ADHD in women and girls: the missed diagnosis

For decades ADHD was understood largely through the behaviour of boys. The result is a generation of women who reached adulthood without an explanation for difficulties they had experienced their whole lives.

Why girls were overlooked

Referral for assessment has historically depended on somebody noticing a problem, and what gets noticed is disruption. A child who cannot sit still, calls out and interrupts creates difficulty for a classroom. A child who sits quietly and drifts does not.

Girls more often show the inattentive pattern of ADHD, which produces exactly that quiet drifting. Their difficulties were real but invisible, and were frequently attributed to being dreamy, disorganised, or not applying themselves.

Masking

Many girls develop strategies to hide their difficulties, and become very good at it. That might mean working far longer on homework than peers to produce comparable results, elaborate list-making and reminder systems, rehearsing conversations in advance, or intense perfectionism to avoid the mistakes they know they are prone to.

Masking works, up to a point. Its cost is exhaustion, and it tends to fail when demands increase, which is why many women are diagnosed at university, after having children, or on taking on a more demanding role.

What it tends to look like in women

The formal criteria are the same regardless of sex, but the presentation often differs.

• Internal restlessness rather than visible hyperactivity — a sense of being unable to switch off
• Mental overwhelm, with too many thoughts at once and difficulty prioritising
• Emotional intensity, including strong reactions to criticism or perceived rejection
• Difficulty with household organisation and the invisible administrative load of running a family
• Chronic tiredness from the effort of compensating
• Long-standing low self-esteem, often from years of being told they were careless or not trying

Hormones and ADHD

Many women report that their ADHD symptoms fluctuate across the menstrual cycle, and that they change during pregnancy, after childbirth and around the perimenopause. This is an area where research is still developing, but it is described consistently enough to be worth raising with your clinician, particularly if symptoms have changed noticeably at one of those points.

Misdiagnosis is common

Because the presentation is quieter, women with ADHD are frequently identified as having anxiety or depression first. Both may genuinely be present, and both can also arise from years of undiagnosed ADHD.

Treatment for anxiety or low mood that produces only partial improvement is worth revisiting. If something has never quite worked, it is reasonable to ask whether the full picture has been seen.

Seeking an assessment as an adult woman

It is common to worry about not being believed, particularly if you have functioned well outwardly. A good assessment takes account of compensation and looks at the effort a result required, not only the result itself.

Bring what you can about your childhood. School reports are useful, and comments such as “could do better if she concentrated” or “often seems distracted” are more meaningful than people realise. A conversation with a parent about what you were like as a child can help too.
