# Girls With Autism Are Often Missed Because Adults Look for the Wrong Signs
Autism in girls goes undiagnosed far more often than in boys, and the reason isn't that girls are less autistic. It's that adults misunderstand how autism shows up in girls.
Conner James Black, PhD, a researcher at the Child Mind Institute, explains that girls with autism often mask or camouflage their symptoms better than boys do. They learn to imitate social behaviors, hide sensory sensitivities, and suppress repetitive behaviors in ways that make autism harder to spot. A girl might sit quietly during class while internally overwhelmed by fluorescent lights and background noise. She might have one intense interest she keeps private rather than talking about it constantly.
The diagnostic criteria for autism were developed largely by observing boys and men. Professionals often look for the stereotypical signs: obvious repetitive behaviors, intense restricted interests, and difficulty with social interaction. When girls don't display these in obvious ways, they slip through.
This diagnostic gap creates real problems. Girls who go undiagnosed often develop anxiety, depression, and burnout as they work harder to fit in. They may struggle academically or socially without understanding why. Some don't receive support until adulthood, missing years of help that could have made school easier.
Parents and teachers can watch for autism signs in girls that look different than textbook descriptions. Girls with autism might have a smaller group of close friends rather than being completely isolated. Their special interests might seem typical, like a focused love of animals or art, but they pursue them with intense depth. They may be perfectionistic or extremely rule-bound. They often experience sensory sensitivities to sounds, textures, or smells but describe them quietly rather than having visible meltdowns.
