No, it's more likely that girls and women learned to mask symptoms early for survival reasons.
If you look at hunter-gatherer societies, ADHD is paramount to survival because it avoids over-harvesting. Too little ADHD produces cultures prone to driving plants and/or animals extinct. ADHD is a critical stop-gap that prevents this. Studies show ADHD gatherers will not only collect more, they will do so in ways that cause far less damage, resulting in a far better second harvest and far better sustainability.
Into more modern times, ADHD was a valuable survival trait. Too little and you became vulnerable to diseases, pests, crop blight, etc. If you wanted a stable population, right the way through to the industrial era, you needed a high level of ADHD in the population.
It is only when neurotypical bosses decided that they had to micromanage everything and decided who lived and who died on the streets that you see ADHD symptoms suddenly and massively suppressed. But masking changes nothing. The levels will still be the same, they're just hidden.
