Autism spectrum dysfunction (hereinafter referred to as "autism") is a group of nervous system development disorders based on social obstacles and repeated stereotypes as the core symptoms。From 1943, Dr. Kenner, Dr. Kenner of John Hopkins University，By 2020 The US Centers for Disease Control and Prevention released the latest version of the incidence report，Autism has been considered to have a male and female ratio of about 4: 1 in the medical course of nearly a century。However, in recent years，This proportion has been questioned more and more。Ethics and complicated reasons for the median，Rough three。

First，The current diagnostic criteria for autism are more suitable for the symptoms of male patients。Social obstacles and repeated stereotypes are the two major diagnostic standards for autism，and the gender differences inherent in men and women，Make autism women's representations on the two core symptoms are not as good as male typical。An American Studies in the United States in 2017，A 7 or 8 -year -old autistic boy is usually alone，and the autistic girls of the same age, they perform together in class activities。Pseudo -imagination games are bet365 Play online games often typical weaknesses of autistic boys，And autistic girls can be more available in fake games and other fake games。It is difficult for men to have the same empathy to others，and a lot of autistic women are even stronger than ordinary people。Visible，Social skills of autistic girls are generally balanced，and a few autism girls who have clearly showed social retreat，But often because it is in line with women's quiet、Inner Show's role is expected and ignored。Therefore, some scholars think，Girls of autism will inadvertently integrate into the society in the way of social participation，Therefore, the degree of symptoms weakened。Tracking Study also confirmed，The possibility of the symptoms of autism girls decreases with age (36%) is indeed higher than autistic boys (26%)。

Autistic girls are not only mild social symptoms，Its repeated stereotypes are not as good as boys。Map、Card、Calendar, etc. is usually a highly recognizable and stereotype indication of autistic boys。Comparison of comparison，Autism girls to animals、Doll、Clothing and other narrow interests are very similar to girls of the same age，It makes it difficult for doctors to distinguish between authenticity。Even，The current universal autism diagnosis table Ados (Autism Diagnostic Observation Schedule) also shows that bet365 Play online games the male tendency of the measurement indicator: The score of autistic girls in narrow interests and stereotypes is significantly lower than boys -this may not be due to Symptoms of autistic girls are lighter，It is probably from the omissions of ADOS on female symptoms。This deviation also makes ADOS's femininity (15%) reaches 2.5 times the male (6%)。So，When the researchers tried to integrate 18 women's autism traits into Ados，There are more female patients who have surfaced。

Second，Asberg women are hidden in ordinary people all year round because they are good at disguise。Some patients with autism will force themselves not to be strange behaviors in the eyes of others to avoid diagnosis，It seems "normal"。And this ability only has low symptoms in the autism spectrum、High IQ、Asperger, which is famous for camouflage, especially Asberg women, can be more。Social occasions that are generally resisted by people with spectrum，Asberg women can cover up emotions、Practice smile、imitation gesture、imitation gesture、Preparatory desk words、Remembering dialogue and other strategies forced yourself to integrate。and the patting hands that are commonly existed for spectrums、Jump and other self -irritating repeated stereotypes，Asberg women can also forcibly hide them: they will convert the impulse of stereotypes bet365 Play online games into gritter、Fisting fisting and other unprecedented muscle movements，or transfers、Graffiti and other social recognition behaviors such as behavior。

Under such camouflage，Many Asberg women are indeed successful，But I have to experience self -denial、Facing energy exhaustion。The physical and mental fatigue brought by the high -intensity camouflage makes as many as 42%of Asberg women being misdiagnosed as anxiety during the growth process、Depression、Occible disorder, etc.，And this kind of secondary misdiagnosis of primary disorders，that is, the autism itself is not diagnosed。Research Discovery，Diagnostic diagnosis caused by camouflage can be up to 30 years，Even unable to diagnose for life。Not only that，The misdiagnosis and misunderstanding caused by camouflage also caused the degree of IQ of autistic women to be damaged by excessive estimation。Over the years，The academic community is unanimously recognized: Although women are less autistic，But women with autism are usually more likely to accompany intellectual obstacles than men。And in recent years, the academic circles have gradually realized，Not autistic women are more likely to have low intelligence，Instead of autism women who are high IQ, women are missed a lot，Most of the women who have diagnosed diagnosis are low and middle -IQs who bet365 live casino games do not have camouflage。

third，The phenomenon of more men and less men in autism groups have their physiological origin。The ratio of women four times that of men is worth scrutiny，But even the male bias of the diagnostic standard、Considering the lurking female Asberg crowd，Autism group still shows the situation of more men and less men and women。This can not help trace the physiological mechanism behind the uneven men and women。

Confirmation of existing research，The pathogenic genes of the Ritter syndrome or brittle X syndrome in the autism spectrum system exist on the X chromosome。This explains the phenomenon of more men and less men and less men in autism spectrum to some extent: women's two X dyeing experiences cover up one of the exceptions，and a single x chromosome of men can make any small samples nowhere to be。At the brain level，The widely recognized neural signal imbalance hypothesis also provides a reasonable explanation for more men and women: the latest research in 2020 found，Social -related brain areas such as the frontal frontal leaf cortex，The excitement of autistic men -inhibit extreme differentiation and cause excessive nerves，The excitement of autism women -not obvious imbalance，The excitement of non -autism -suppression is almost balanced。other，Women who have stronger camouflage capabilities，bet365 live casino games It is excited -more inhibitory becomes more balanced、The closer to ordinary women。Although the academic community is difficult to determine the excitement of neural signals — whether to suppress imbalance is the cause of the pathogenicity of autism or compensation result，But the degree of excitement -inhibitory is indeed highly corresponding to the phenomenon of more men and young men and women in autism groups。

The above genetic and neurological hypotheses provides possible explanations for the causes of uneven autism men and women，But the complicated cause of autism itself determines that the essence of more men and women is still difficult to see at this stage。The academic circles are generally believed today，The real male and female ratio is not as serious as 4: 1，But even if the interference is removed，The number of men with autism men may still be two times that of women。Are there less women in autism? At least now，The answer to this question is still positive。
