What is written below is all theoretical
The definition of AS/"Very" HFA: In the Nazi culture, the very introvert and nonsocial people were considered weak and rejected and so ..."genetically inferior" , the genetically inferiors were considered as dangerous to the German Reich , they had no place in the greater Germany since the empire had to be "purified of all antisocial and Jewish elements".
For that reason, categorization of people was encouraged by Nazi Germany and those different people and nonsocial introvert people had to be labeled in order to be recognized.
Therefore, an Austrian pediatrician(was not even a neurologist or psychiatrist!!) who lived in a country under strong Nazi influence, has accomplished this mission by creating a new "medical" diagnosis on the basis of a mediocre scientific study that was done on only FOUR boys and linked it to a real disorder which is Autism , this new diagnosis was called by his name as Asperger's syndrome .
After a while of the fall of the Nazi empire , this personality type described above is no longer desired nor accepted by the rest of the world too (even by the parents), the world is leaning more and more into extroverts and therefore this minority of people with such personality type feel alien and rejected and often fall in depression and anti-social isolation.
As result of the increase of these people's complains about their 'difference' as well the parent's complains about the 'difference' of their kids, the psychiatric industry took benefit from those people and adopted the same Label created by Hans Asperger to diagnose those people.
Like in the case of ADHD , the Psychiatric industry started to promote that diagnosis with biased brain studies on kids who are already on drugs and Molecular Psychiatry promoted unclear genetic studies every while showing how Asperger is related to many genes and environmental factors (if it's a personality type then It's surely related to many genes and environmental factors , any personality type is partly genetic and can somehow be INHERITED too.). The asperger's symptoms can all be considered as normal behavioral traits like obsession and lack of empathy (quirky but normal) in which almost everyone in the world has at least one or two of such traits.
They did a great Marketing job and nowadays millions Antidepressants and stimulants are being prescribed and sold to those who are diagnosed as "Asperger",those introverts have just fell victims under a psychiatric Label and embraced it in order to feel an explanation for their difference.
Classic Autism: A real brain disorder , not related to AS, its cause is unknown but probably related to genetic and environmental factors (like mercury , a well known neurotoxin found in many products and food). Classic Autism is not even close to Asperger's syndrome.
Classic auties have those features:
# a profound lack of affect or emotional contact with others
# an intense wish for sameness in routines
# muteness or abnormality of speech
# fascination with manipulating objects
# high levels of visuo-spatial skills, but major learning difficulties in other areas
# attractive, alert and intelligent appearance.
Diagnosis:
Unlike the Asgerger's symptoms , those symptoms are very clearly abnormal
* Very limited eye contact,
* Avoidance of physical contact,
* Inappropriate facial expressions and emotional responses,
* Inflexibility in routines,
* Repetitive movements like hand flapping,
* Delay in the development of speech, and speech without communicative gestures,
* Difficulty or inability to converse,
* Inflexible routines,
* Unusual interests with certain objects, and
* Onset of at least one of the above systems before the age of three.
Classic autism is a real DISABILITY because it interferes with one's ability to take care of his own (unless if he's professionally taught how to live by his/her , like the blind person) and its symptoms interferes with one's daily activities too
Classic Autism IS a spectrum where there are High functioning autistics and low functioning autistics but in both cases the symptoms can be easily be spot ....as for those who are very very veryyyyyyy high functioning autistics , those are just NTs people.
PS: What's so funny that many Dxed Aspies and Self-Dxed Aspies think they have the right to talk in the name of 'whole Autism' , including Classic Autism, and promote the idea that Autism is not is real disability and not even abnormality but just "neurodifference" and refuse any study that suggests that Autism may be caused by an external factor like Mercury or pollution because they relate AS to Classic Autism and so don't want to be related to abnormality.
