Definition
Autistic girls and women are frequently identified later or missed entirely, partly because diagnostic criteria were built largely on studies of boys. Traits can present differently, with more social camouflaging and interests that look conventional on the surface.
Why It Matters
A 2017 meta-analysis concluded that the true male-to-female ratio is closer to 3 to 1 than the often assumed 4 to 1, and that girls who meet criteria are at disproportionate risk of not receiving a clinical diagnosis. A 2022 commentary in JAMA Network Open notes that the behaviors behind current diagnostic tools were derived from samples of children who were predominantly White and male. Missed diagnosis can leave girls and women without support, and higher camouflaging is associated with worse mental health. Understanding the different presentation helps them be seen, believed, and supported.
Common Misconception
Girls are not inherently less autistic; they have been under-identified. A girl making eye contact, having friends, or masking well can absolutely be autistic, and 'she doesn't look autistic' reflects a narrow stereotype.
