Autism evaluation that sees what others miss.

Why autism is missed in girls.

For decades, autism research and diagnostic criteria were built almost exclusively on studies of boys. The result is a diagnostic framework that captures one version of autism (the version most visible in male presentations) while systematically missing the way autism often manifests in girls and women. This is not a small gap. Research suggests that girls are diagnosed an average of two to three years later than boys, and many are never diagnosed at all.

The primary reason is masking. From a very young age, many autistic girls learn to observe and imitate the social behavior of their peers. They study facial expressions, memorize conversational scripts, and develop rules for social situations that neurotypical children navigate intuitively. On the surface, this can make them appear socially competent, even socially successful. A girl who maintains one or two friendships, makes eye contact, and follows classroom expectations may never trigger concern from teachers or pediatricians using standard screening tools.

But the internal experience tells a different story. Masking is cognitively and emotionally exhausting. Many autistic girls describe holding themselves together at school only to “fall apart” at home: meltdowns, shutdowns, intense anxiety, deep fatigue. Parents see a child who is clearly struggling, but the school reports a student who is “fine.” This discrepancy is often dismissed or attributed to normal developmental variation, when it is actually one of the most reliable indicators of a masked autistic presentation.

Girls on the spectrum are also more likely to present with internalizing symptoms rather than the externalizing behaviors most commonly associated with autism. Instead of overt repetitive behaviors, they may have intense, narrow interests that are socially acceptable (animals, art, reading) and therefore unremarkable to observers. Their relationships may appear typical but are maintained through enormous effort and anxiety. Where you might expect meltdowns in the classroom, you may see perfectionism, selective mutism, or chronic stomach aches.

The consequences of missed diagnosis are significant. Unidentified autistic girls often accumulate other diagnoses over time (anxiety, depression, ADHD, oppositional defiant disorder, even eating disorders) without anyone considering autism as the underlying explanation. They receive treatments that address symptoms but not the root cause, and they internalize a narrative that something is fundamentally wrong with them that they cannot quite name.

Our evaluations are specifically designed to identify these presentations. We use gold-standard autism assessment tools (including the ADOS-2) alongside a detailed clinical interview that asks about internal experience, not just observable behavior. We look at the gap between school reports and home reports. We listen to parent observations that have been dismissed elsewhere. We understand that a girl who makes eye contact, has friends, and earns good grades can still be autistic, because autism is about how the brain processes information, not how well someone has learned to perform neurotypicality.
