What gender is more likely to get autism?
Autism affects more boys than girls. The ratio of boys to girls with autism is about 4:1. The National Autistic Society's site (link below) explains more about the different level of occurrence in males and females.For the most severe cases of autism, the ratio of autism in boys and girls is nearly 1:1. This has led to speculation by some of the most noted experts in the field that girls with autism have a few symptoms that differ from boys and thus are underdiagnosed. (The original description of autism was based on case studies of males, and the underlying reason for some of the behaviors might manifest differently in males and females.) For example, instead of acting aggressive, they might withdraw and be viewed as very shy and passive. Also, their obsession-like special interests (such as animals) cause less concern. So, even though they might have a great many behaviors identified with autism, girls with autism might not come to the notice of parents or educators because of those few behaviors where they differ from males might mean that no concern is triggered despite matching most of the characteristics.I don't agree with above poster regarding girls being under-diagnosed and reasons why. There are not a "few symptoms" that lead to a diagnosis of autism, like there are for other medical maladies. Basically, a very well trained person must observe the child, speak to the parents and review anecdotal reports regarding the child's behavior. Then and only then can the trained individual say that the child (may) have some degree of autism. There is no absolute test, and anyone that says there is, is not a true trained professional. When making a diagnosis, there is a list of target behaviors, about 20 or so. If the child exhibits a high degree of these behaviors, (like 12 or 15 out of 20) then it's pretty safe to say that the child fits somewhere on the autism spectrum. Every child is different and acts out in different degrees. That is why I question the answer above. AGGRESSIVENESS in and of itself is not necessarily a sign of autism. However, combined with 10 other target behaviors, it may well fit the autism profile. Same with OCD or ADHD. Alone, these behaviors don't really tell you the whole story. However, combined with 10 or 12 other target behaviors, then you might be talking autism. AND, boysand girls would be evaluated on the same scale, looking for the same target behaviors that would suggest autism in the first place! I hope this helps clear things up a bit for some folks. I've been working with adults and children with autism for 30+ years and it is a very complicated, misunderstood disorder.... The female differs from the male in her enhanced ability to rid her body of environmental foreign toxins such as fluorine, chloride, and bromine compounds. These compounds, found in paints, cleaners, plastics, fire retardants in new clothing, bedding, towels, coatings to keep oils and greases from leaching (microwave popcorn bags, carpet coatings), etc, are absorbed by the infant and stay there from 5 to 8 years. This also accounts for the fact that the first child is at a greater risk of having autism, because he/she is the one with the new crib, BFR (brominated fire retardant) treated mattress, freshly painted or cleaned room and carpet, new toys, etc. This is why products such as "Scotchgard" and "Stainmaster" have disappeared, and Biphenol A (BPA) is under fire. see: AutismApocalypse.com
