ADHD in women and girls

A pattern of missed diagnosis

For decades, understanding of ADHD was shaped largely by studies and observations of hyperactive young boys. This meant diagnostic criteria and clinical awareness didn't reflect how ADHD often shows up in girls and women, leading to widespread under-recognition. Many women are only diagnosed in adulthood, sometimes after their own child is diagnosed and they recognise similar traits in themselves.

This isn't because ADHD is less common in women — it's increasingly understood that it's simply been missed more often, due to how it tends to present and how it's been perceived.

How ADHD can look different in girls and women

While there's a huge amount of individual variation, some patterns are commonly described:

• More inattentive traits, fewer hyperactive ones – many girls and women experience the inattentive presentation, which is quieter and less disruptive than hyperactive-impulsive traits, making it easier to overlook.
• Masking – learning to hide or compensate for difficulties, often from a young age, to fit in socially or meet expectations. This can include copying peers, over-preparing, or suppressing visible signs of struggle.
• Internalised struggles – difficulties may show up as anxiety, low self-esteem, or perfectionism rather than obvious disruptive behaviour.
• Daydreaming rather than hyperactivity – some girls are described as "away with the fairies" or a bit ditzy rather than disruptive, which can be misread as simply being quiet or scatterbrained.
• High achievement alongside high effort – some women appear to cope well externally, while privately expending enormous effort to keep up, often leading to burnout.

Hormones and ADHD

Hormonal fluctuations across the menstrual cycle, pregnancy, and menopause can affect how ADHD traits are experienced. Some women notice that symptoms feel more pronounced at certain points in their cycle, or that perimenopause brings a noticeable increase in attention and memory difficulties. This is an area of ongoing research, and if you notice patterns like this, it's worth mentioning to your GP or specialist, as it may be relevant to your overall care.

Why late diagnosis happens so often

Several factors contribute to women and girls being diagnosed later, or not at all:

• Diagnostic tools historically developed and validated on predominantly male samples
• Social expectations that encourage girls to be quiet, compliant and organised, which can drive stronger masking
• Co-occurring anxiety or depression sometimes being treated as the primary issue, without exploring an underlying ADHD picture
• A lack of professional awareness of how differently ADHD can present, though this is gradually improving

The impact of a late diagnosis

Being diagnosed as an adult, after years without understanding, can bring a complicated mix of emotions. Many women describe relief at finally having an explanation, alongside grief for the years of struggle, self-blame, or feeling like they were somehow failing compared to others. These feelings are valid, and it can help to talk them through with a therapist familiar with ADHD, or to connect with others who've had similar experiences.

Seeking assessment as a woman or girl

If you suspect ADHD, either for yourself or a daughter, it's worth knowing that assessment approaches informed by current understanding take a broader view of how ADHD can present, beyond the classic hyperactive stereotype. When seeking assessment:

• Mention any history of masking, internalised difficulties, or anxiety alongside attention-related traits
• Share developmental history, including school reports or reflections from parents, where possible
• Ask whether the assessing clinician has specific experience with female presentations of ADHD, if this feels important to you
• Be open about hormonal patterns if relevant, as this can add useful context

Support that reflects your experience

Support for women with ADHD can include the same broad options as for anyone else — strategies, therapy, and sometimes medication — but it can help to find support that acknowledges the specific patterns often seen in women, such as masking, burnout, and hormonal influences. Peer support groups and communities specifically for women with ADHD can also be a valuable source of understanding and practical tips.

Next steps

If this guide resonates with your own experience or that of your daughter, consider speaking to a GP as a starting point. They can discuss your concerns and outline possible routes to a full assessment with a qualified clinician who can consider your individual history and presentation.
