ADHD in girls — why it's
missed and what it looks like
ADHD in girls rarely looks like the textbook picture. It is quieter, more internal, and far more likely to be dismissed — or misdiagnosed as anxiety. Here is what to look for.
The hidden epidemic
Why ADHD in girls is so frequently missed
For decades, ADHD research focused almost exclusively on boys. The result is a diagnostic framework that describes male presentations well — and female presentations poorly.
Biased research
ADHD diagnostic criteria were built from studies predominantly involving boys. The criteria describe hyperactive, disruptive behaviour well — but miss the quieter, inattentive presentations more common in girls.
Expert masking
Girls are socialised to be compliant and socially adept. Many develop sophisticated coping strategies that hide their difficulties from teachers, parents and clinicians — at enormous personal cost.
Misdiagnosed as anxiety
The anxiety, low self-esteem and exhaustion that come from living with undiagnosed ADHD are frequently treated as the primary condition. The underlying ADHD is never identified.
Later diagnosis
Girls are most commonly diagnosed in their teens, 20s or 30s — often triggered by a child's diagnosis, a major life change, or complete burnout. Many spend years not understanding why life feels so hard.
A 2019 study found that girls with ADHD wait an average of 4 years longer than boys to receive a diagnosis. During those years, many develop significant secondary mental health difficulties — anxiety, depression and disordered eating — that could have been avoided with earlier identification.
What to look for
Signs of ADHD in girls (aged 6–17)
These are the presentations that are most frequently overlooked in school settings and GP surgeries — and most commonly seen in girls with undiagnosed ADHD.
Adult presentation
Signs of ADHD in women
Many women receive their first ADHD diagnosis in their 30s or 40s — often after years of being told they are anxious, disorganised or not trying hard enough.
Oestrogen influences dopamine regulation — the same neurotransmitter system affected by ADHD. Many women find ADHD symptoms worsen premenstrually, during pregnancy and significantly during perimenopause when oestrogen levels decline. If you have noticed your symptoms are cyclical or have worsened with age, this may explain why.

Female-led clinical team
Carrie Young, our Clinical Director, brings both clinical expertise and lived understanding to ADHD assessments — creating an environment where female presentations are fully recognised.
Assessed at home
Remote assessments via secure video mean girls and women are assessed in their natural environment — reducing anxiety and producing more authentic clinical data.
QbCheck included
Objective testing provides measurable evidence independent of the subjective presentation — particularly valuable when masking makes symptoms less visible in a clinical setting.
