One draws attention without meaning to. The other works twice as hard to fade into the background, hoping nobody notices how much effort it takes just to keep up. Both have ADHD. Only one of them is ever likely to be asked about it.
ADHD doesn’t look the same in every girl. The noisier presentation gets flagged. The quieter one gets missed for years, mistaken for shyness, daydreaming or simply trying not hard enough.
ADHD affects how girls regulate attention, activity and impulse control. It presents in three recognised ways, and understanding which one fits your daughter is part of getting her the right support.
Children who are disruptive get referred. Children who are quiet rarely are. Since most girls with ADHD fall into the second group, the diagnosis is delayed by years for no reason other than presentation. In UK primary care records, boys are diagnosed at nearly four times the rate of girls,[3] not because girls have ADHD less often, but because their symptoms are less visible and the referral threshold is higher.[4]
The consequences compound over time. Many girls are diagnosed with anxiety or depression first, or are simply told they lack confidence,[5] when the underlying cause was never identified. By adolescence the gap between effort and results has often widened considerably, and NHS waiting times add further delay before any assessment is even possible.
The clinical distinction comes down to three things:
1
2
3
At school, she might be described as capable but distracted, someone who tries hard but somehow still falls behind. Instructions feel unclear even after they are repeated. She keeps misplacing things she genuinely cares about, which causes her real distress rather than indifference. Over time, the gap between what she knows and what she can actually produce starts to chip away at how she sees herself.
Socially, it can feel just as hard. Conversations move faster than she can keep up with, social cues are missed, and small moments get replayed afterwards with intense self-criticism. From the outside this can look like quietness or withdrawal. From the inside, it is exhausting.
Girls with ADHD are often intensely empathetic, creatively perceptive and deeply curious about the things that matter to them. Many have a capacity for hyperfocus on subjects they care about that produces work of real depth and quality. A diagnosis does not take any of that away. It explains why the gap between how capable she is and how she has been performing has felt so inexplicably wide.
One factor that makes ADHD in girls particularly distinct is the role hormones play, both during puberty and beyond.
Between 60 and 80% of children with ADHD have at least one co-occurring condition.[7] For girls, the most common include learning disorders such as dyslexia, dysgraphia and dyscalculia, alongside internalising conditions like anxiety, depression and heightened sensitivity. Girls with ADHD are more likely than boys with ADHD to develop internalising conditions such as anxiety and depression,[8] and ADHD is also linked with Tourette’s, bipolar disorder and autism spectrum disorder.[9]
If your daughter has been assessed for ADHD, it is worth discussing with the assessing clinician whether any of these should also be explored.
