I suppose I could try to just regurgitate the article but it would be better to let the article speak for itself.
In addition to how autism displays in girls, we have some interesting clues as to the genetic basis for it. And girls on the higher end of the spectrum may have difficulty getting diagnosed at all.
Scientific American: Autism – It is different in girls
Autism in Girls
- One in 68 children in the U.S. is affected by autism—but new research suggests that current diagnostic methods overlook girls, meaning even more kids may be “on the spectrum”, maybe 1 in 40.
- Behavioral and preliminary neuroimaging findings suggest autism manifests differently in girls. Notably, females with autism may be closer to typically developing males in their social abilities than typical girls or boys with autism.
- Girls with autism may be harder to diagnose for several reasons, including criteria developed specifically around males and overlapping diagnoses such as obsessive-compulsive disorder or anorexia.
