Does ADHD look different in women and AFAB adults?

Yes, it often does, for two different reasons that are easy to confuse. The first is social: people who were raised, treated, and seen as girls are more often praised for being quiet and compliant and steered away from visible disruption, so ADHD in this group tends to turn inward, looking like inattention, anxiety, or exhausting effort to keep up rather than obvious hyperactivity. The second is biological: for people with menstrual cycles, fluctuating oestrogen appears to shift attention and regulation across the month. These differences are part of why ADHD has been so badly under-recognised in women and AFAB adults. Two cautions matter here. The hormonal research is based almost entirely on cisgender women, so it does not map neatly onto AFAB people on gender-affirming hormone therapy, where the picture is different and barely studied. And being AFAB is not the same as having been a girl; what this group more often shares is a history of being raised and treated as one, a social force that shaped how their ADHD was read.

The social reason

When people picture ADHD, they still tend to picture a boy who cannot sit still. That image shaped the research, the diagnostic criteria, and what teachers and parents were watching for (Martin, 2024). It left a great deal of ADHD invisible, and it left this group particularly exposed.

Children who were raised and treated as girls tend to be socialised differently. They are more often rewarded for being quiet, accommodating, and self-managing, and corrected more sharply when they are not. So the same underlying ADHD that might show up as a child bouncing off the walls more often shows up here as a mind that races while the body stays still, as daydreaming, as losing the thread, as a quiet, private sense of falling behind while working twice as hard to hide it. None of that draws a teacher's eye the way disruption does. A recent systematic review of ADHD in adult women describes exactly this pattern of inattentive, internalised presentation slipping through the net for years (Attoe & Climie, 2023).

I want to be careful with the language here, because it matters. The people this describes do not share one gender. Some are women, some are trans men, some are non-binary, and some who were raised as girls felt at home with that at the time and others did not. Gender can be fluid, and it is not mine to assign. What this group more often shares is the experience of having been raised, treated, and seen as girls. That social treatment is a real force, and it shaped how their ADHD was read, but it does not settle who they were then or who they are now.

The biological reason

There is a second thread, and it is genuinely physical. For people who menstruate, ADHD symptoms appear to fluctuate across the menstrual cycle. As oestrogen falls in the days before a period, focus and emotional regulation can get measurably harder (Eng et al., 2024). Many people describe their attention shifting predictably across the month without ever having connected it to their cycle.

Here is where I have to be honest about the limits of what we know. That research is built almost entirely on cisgender women. It does not map cleanly onto AFAB people taking gender-affirming hormone therapy, where the hormonal picture is altered. And the wider research on how gender identity and gender-affirming care interact with ADHD is still very thin, mostly small studies of how common ADHD is, with little on how it actually presents. So if you are on hormone therapy and your experience does not match the menstrual-cycle account, that is not a contradiction. It is a gap in the research, not in you.

What this means in practice

Put the two threads together and the picture makes sense. ADHD in women and AFAB adults has often been quieter on the outside, heavier on the inside, and tangled up with hormonal shifts that were rarely asked about. That combination is a large part of why so many people in this group reach adulthood without anyone having recognised it.

If you are reading this and a pattern you have carried for years is starting to come into focus, I would gently say that the fact it was missed is not evidence that it was not there. It is evidence of how narrow the picture has been. You do not need to fit the textbook version, and you do not need to have it all sorted before you bring it to someone who can look at it with you.
