For years, an autistic girl could sit quietly in a classroom, get good grades, have a few friends and never be recognized as autistic at all.
That is part of the reason autism has historically been diagnosed far more often in boys.
Autism does not belong to one s*x, but researchers increasingly understand that it can be less obvious in some girls and women. Instead of displaying behaviors adults immediately associate with autism, a girl may become extraordinarily good at watching other people and copying what works.
She studies how other girls talk. Rehearses conversations before they happen. Forces herself to make eye contact. Memorizes jokes and expressions. Suppresses movements that might attract attention. She may even construct different versions of herself for different social situations.
Researchers often call this masking or camouflaging.
Even intense interests can be overlooked. A boy obsessively interested in train schedules might attract attention. A girl intensely focused on horses, celebrities, literature or a particular friendship may simply be described as passionate. What matters is not necessarily the subject, but the intensity and function of the interest.
And masking can come at a price.
Holding yourself together through an entire school day can be exhausting. Some girls appear socially capable in public, then become overwhelmed at home. Anxiety, depression or eating disorders may be noticed long before anyone considers autism.
There is another problem: much of the early research that shaped our understanding of autism disproportionately involved boys and men. The picture clinicians learned to recognize was therefore incomplete.
That picture is changing.
Women are now being diagnosed in adulthood after spending decades believing they were simply too sensitive, too anxious, too intense or inexplicably exhausted by things everyone else seemed able to do.
Sometimes autism wasn't absent.
The signs were there.
The girl had simply spent years learning how not to let anyone see them.
