A recent study handled by the Kennedy Krieger Institute located in Baltimore discovered that not only are females much less likely to be diagnosed with autism spectrum disorder (ASD), but they are also diagnosed much later on in life in comparison to males.
The Interactive Autism Network – also known as IAN – supplied their online data registry to the Institute. Information was supplied from almost 50,000 families and individuals affected by autism. The study factored in the age and gender of the individuals diagnosed.
Pervasive developmental disorder, diagnosed by delayed growth in social and communicative areas, affected girls beginning at age four in comparison to boys at an average age of 3.8. As well as this, Asperger’s Syndrome was also more common later in girls’ lives, while earlier in boys’. The overall ratio of boys versus girls in the IAN database was almost 4.5 to 1.
This link could be related to the female tendency to be more shy and quiet rather than males. Dr. Paul Lipkin, the director of IAN, says that these autistic behaviors are often written off as shyness. He also stated that girls struggle more often than boys with ability to understand social cues from others, whereas boys struggle with more obvious mannerisms. This shyness can deter professionals from making the diagnosis, while the true cause remains beneath the surface.
Females with autism cannot always be treated identically to males with ASD. This study aims to help determine the recognizable traits in females that have previously led to later diagnoses. This gender gap can hopefully begin to close by implementing social skills training for girls who exhibit these behaviors. Treating this should not change who these children are as people, but should instead allow them to be more aware and flexible with their emotions and the emotions of those around them.
