Differences in Autism Symptoms for Boys and Girls

Difference in Autism Symptoms for Boys and GirlsThe severity of symptoms varies greatly among individuals diagnosed with ASD. One aspect of autism that doesn’t receive a great deal of attention is the way the different way the condition manifests in girls and boys.

We have known for many years that autism is more common in boys than girls. Latest CDC figures show that as much as 5 times as many boys are diagnosed with autism than girls. The disorder appears different in the sexes, and these differences may have important implications for both diagnosis and treatment.

There is currently no adequate explanation for this imbalance in the sex ratio, but Dr. Peter Szatmari, a professor and the head of the Division of Child and Adolescent Psychiatry in the Department of Psychiatry and Behavioral Neurosciences at McMaster University believes that something could be protecting girls from developing ASD and other developmental disorders. That factor could be hormone levels in utero, epigenetic factors that turn autism susceptibility genes “on” and “off” during development, or the fact that young girls have in general better social skills than boys and so need a bigger “dose” of what causes ASD to cross that threshold to being impaired.

Dr Szatmari explains “It is possible that those possible protective factors, once identified and understood, could play an important role in pointing toward new treatments and interventions that capitalize on those protective factors and so make a real difference to long-term outcomes.”

The clinical expression of autism is also different in boys. Generally speaking, girls with autism have greater learning disabilities and more problems academically than boys.

Higher-functioning girls with ASD are may be missed by clinicians who are not experts in diagnosis, Dr Szatmari states. There is some evidence that among this subgroup, girls have better social skills than higher-functioning boys with ASD and so are not diagnosed as readily. Although, the symptoms of ASD can appear as extreme shyness or anxiety in girls, masking that they may not be responsive to the social cues of others.

Girls on the autism spectrum have fewer repetitive behaviors such as rocking and spinning and less sensory sensitivity than boys with ASD. Since these signs are subtle, doctors may not recognize the disorder. Diagnosis at a later age reduces the chances of early treatment, which is understood to provide a better outcome.

Some evidence suggests that girls with ASD are bullied less often than boys. They appear to blend in more easily with their peers and are less often the victim of bullying by other girls.

Understanding these differences both biologically and experientially holds the promise of improving the long-term outcome of all children with ASD. Most important, clinicians need to be sensitive to how the disorder shows up in girls so that those affected can receive early intervention as soon as possible.
