There has been something unusual and inexplicable about autism from the very beginning. When psychiatrist Leo Kanner was conducting some of the first studies that led to a formal diagnosis for the syndrome, thesis statement for oppositional defiant disorder, he noticed something strange about his test subjects: there were more than four times as many boys that showed symptoms as girls.
Between four and five times as many boys as girls are diagnosed with ASD each year, and the same has been true for as far back as there are records. Through the modern surge in diagnoses and the intensive investigations into this phenomenon that followed, that ratio has remained relatively static. Why are boys apparently more susceptible to ASD? But recent research has begun to open up some hypotheses about the issue that might shed light on both autism and on some of the basic and ancient differences between the male and the female brain.
Today, as gender identity and equality have become loaded political questions, such a statement would immediately draw fire. The suggestion that either sex might be innately cognitively inferior to the other—even if only in particular realms—is subject to much debate today. And the conception of intelligence itself remains difficult to define unequivocally, leaving perceptions of it open to different interpretations. Researchers have long known that at the most basic level, there are differences in the male and female brain.
Male brains tend to be disproportionately larger than female brains. On standard IQ tests, men and women consistently test to the same average score—but that is by design, since the tests are structured to elicit an average of among the general population. When IQ tests were first being developed, girls routinely scored higher than boys up until around the age of Despite having the same overall average, within some components of the overall IQ test there are differences in scores between men and women.
Interestingly, different tests have found that women tend to score higher on verbal abilities while men outperform on visuospatial abilities. Taken to extremes, of course, this almost perfectly describes one of the core symptoms of ASD: deficits in verbal communication. So if men are already inclined to be less skilled at verbal communication, is this what makes them more susceptible to autism?
According to some researchers, the reason is that autism is an excessive expression of those aspects of brain development that are already pronounced in the male brain. The extreme male brain theory posits that it is an overdevelopment in the male traits of cognition that causes ASD patients to over-systematize, thesis statement for oppositional defiant disorder, leading to a breakdown of verbal and social capacities.
On the other hand, researchers in Canada in undertook a genetic study of ASD patients and found that around one percent thesis statement for oppositional defiant disorder the males tested had a particular mutation in a certain thesis statement for oppositional defiant disorder on their X-chromosome.
If the thesis statement for oppositional defiant disorder were found to be linked to ASD it could explain some of the preponderance of ASD among boys. And even more recently, thesis statement for oppositional defiant disorder, scientists in Germany found a positive correlation between a thin cortex and the likelihood of an ASD diagnosis.
Since women reliably have greater cortical thickness than men, this could indicate that the male brain is simply more vulnerable to whatever structural changes bring about ASD. The search for a definitive answer as to why more boys than girls suffer from ASD is only one aspect of the larger search for the causes behind autism and is not likely to be resolved until that central mystery is itself cleared up. Why are Boys More Likely to Have Autism?
