Girls with autism often go undiagnosed because their symptoms look different from boys', and adults miss the signs entirely. Conner James Black, PhD, a researcher at the Child Mind Institute, explains that girls mask their autism more effectively than boys do, camouflaging their struggles in social situations and at school.
The diagnostic criteria for autism were developed largely based on how autism presents in boys. Boys tend to show more obvious repetitive behaviors and intense, narrow interests. Girls, by contrast, often develop sophisticated social mimicry skills. They watch their peers closely and learn to blend in, hiding their sensory sensitivities and social difficulties behind a carefully constructed facade.
This masking comes at a real cost. Girls with undiagnosed autism often experience anxiety, depression, and burnout because they're working constantly to appear "normal." They expend enormous mental energy monitoring their behavior and managing social interactions that don't come naturally to them.
Parents and teachers frequently miss autism in girls because they focus on the wrong checklist. A girl who loves reading or art intensely might not fit the stereotype of autism, even though her deep interest represents a classic autistic trait. A girl who struggles silently with eye contact or sensory overload but manages to get good grades flies under the radar entirely.
Black emphasizes that recognizing autism in girls matters for their wellbeing. Diagnosis opens doors to support, self-understanding, and the chance to stop exhausting themselves through masking. Girls who receive early identification benefit from accommodations at school and strategies to manage sensory sensitivities.
The shift toward better identification requires adults to expand their understanding of what autism looks like. Teachers and pediatricians need training on autism's presentation in girls. Parents should watch for social anxiety, perfectionism, difficulty with unstructured time, and sensory sensitivities, not just the repetitive behaviors associated with boys.
