Since there are so many variations in the spectrum, and no 2 autistic children are the same, I don't know if there is a clear cut definition of high-functioning. You might try the Autism Speaks website for more info.

That is a very good website.  There is a wide variation in children on the spectrum.  On one side you have children that have severe communication deficites and delays and on the other as with Aspergers, children are highly verbal.  This is one variable that seperates 'regular autism' as you said from high functioning.  I'm sure there are many more variables.  good luck

The technical distinction for a diagnosis of High Functioning Autism is based on IQ scores.  Children with an IQ above 70 are considered high functioning.  But most clinicians use the term in their own way, which is what makes it even more confusing.  High Functioning in general refers to the fact that there are no significant cognitive delays.

I found this interesting post from Autism support network...I am sure it will help many others too !!


" People may get a diagnosis of high-functioning autism or Asperger syndrome. Here, we explain the reason for there being two terms.

High-functioning autism and Asperger syndrome are both part of the 'autism spectrum'. The main difference between the two is thought to be in language development: people with Asperger syndrome, typically, will not have had delayed language development when younger.

The Autism Helpline is often asked what the difference is between high-functioning autism and Asperger syndrome. Sometimes it can seem like the two diagnoses are given on an almost interchangeable basis. The controversy over the differences between these two diagnoses goes back a long way, this article examines some of the literature available and the reasoning behind the existence of the two separate terms.

The term autism has an unusual history. It was originally coined by a psychiatrist Eugen Bleuler in 1911 to describe what he perceived as one of the key symptoms of schizophrenia, that of social withdrawal. Autism, literally meaning selfism, seemed to him to describe the active detachment which affected many of his patients. In the 1940s when Leo Kanner in America and Hans Asperger in Austria were both beginning to identify the existence of autism they separately stumbled on this term which they felt described what they were witnessing in the children they were treating.

In Kanner's case he started from the premise that these children were experiencing childhood schizophrenia. In time he became aware that they were not exhibiting all the symptoms of schizophrenia and used the phrase infantile autism to describe their condition. In the case of Hans Asperger, he identified a personality disorder affecting some of the children referred to his child psychiatry clinic which he felt was described albeit imperfectly by the term autism. His acute identification of autism was extraordinarily ahead of its time considering he was among the first people to chart it. Unlike schizophrenic patients, children with autism do not show a disintegration of personality. They are not psychotic instead they show a greater or lesser degree of psychopathy.

Kanner, an American, was writing in English. His paper was published in the UK where it gained a lot of attention. The term infantile autism became increasingly widely used in the 1950s and 60s, more and more children were diagnosed with the condition. In the English-speaking world the work of Hans Asperger went largely ignored. However, in Europe he continued to conduct research and have an influence over child psychiatry.

We don't know if Kanner was ever aware of the work of Asperger but we do know that Asperger in later years read about the work of Leo Kanner. He argued, albeit unconvincingly, that they had identified separate syndromes with a great overlap. Other academics began to argue that Asperger's and Kanner's autism were the same syndrome. Most notably Judith Gould and Lorna Wing in their ground-breaking study in Camberwell in the late 1970s came to the conclusion that autism existed on a continuum. In 1981, Lorna Wing used the phrase Asperger syndrome in a research paper to describe a distinct sub-group of patients that she had been seeing. The term became much more widely used in the English-speaking world as a result. Some professionals have felt that Asperger syndrome is a more acceptable diagnosis from the point of view of parents. They argue that there is a social stigma attached to autism which is not attached to the term Asperger syndrome.

"In the case of Asperger syndrome its recognition has resulted in its placement among developmental disorders in general and autistic spectrum disorders in particular. It may well be proved to have no independent existence but this does not detract from Aspergers achievement in discerning something very special in the children he described."
Uta Frith, 1998

Gillberg and Ehlers (1998) identify four main areas where controversy over the difference in diagnosis still exists.

Level of cognitive functioning

The view that Asperger syndrome is autism without any additional learning disability is helpful from the diagnostic point of view as it is fairly easy to make a distinction in these circumstances. However, Asperger himself said that there might be unusual circumstances where a person could present the symptoms of Asperger syndrome with additional learning disability. It is widely recognised that high functioning autism cannot occur in someone with an IQ below 65-70.

Motor skills

In recent years the view that Asperger syndrome can only occur when there are additional difficulties with motor skills has become more prominent. Certainly Asperger himself was well aware of the prevalence of motor skill problems in the group of people he tried to describe. It seems likely that most children with Asperger syndrome experience poor co-ordination and difficulties with fine motor control. However, many children with higher functioning autism will also have difficulties in these areas.

Language development

This is the area that probably causes the greatest controversy. Both ICD10 and DSM IV state that for a diagnosis of Asperger syndrome then spoken language development must be normal. Children with high functioning autism may have had significant language delay. However, Asperger's original descriptions of the condition stated that speech and language peculiarities are a key feature of Asperger syndrome. Often diagnoses of Asperger syndrome are made when a child is quite old and they or their parents may have difficulty remembering the details of their language development.

Age of onset

A diagnosis of HFA and one of AS can be made in the same individual at different stages of development. Occasionally a child has been diagnosed with high functioning autism in early childhood and this diagnosis has been changed to Asperger syndrome when they started school. Some diagnosticians are clearly of the view that Asperger syndrome cannot be diagnosed before a child starts school. However this is largely because areas such as social skills deficits may not become apparent until a child spends a lot of time in social settings.

To summarise:

* Both people with HFA and AS are affected by the triad of impairments common to all people with autism.

* Both groups are likely to be of average or above average intelligence.

* The debate as to whether we need two diagnostic terms is ongoing.

* However, there may be features such as age of onset and motor skill deficits which differentiate the two conditions.

Although it is frustrating to be given a diagnosis which has yet to be clearly defined it is worth remembering that the fundamental presentation of the two conditions is largely the same. This means that treatments, therapies and educational approaches should also be largely similar. At the same time, all people with autism or Asperger syndrome are unique and have their own special skills and abilities. These deserve as much recognition as the areas they have difficulty in.

If you or your son or daughter has recently been given a diagnosis of either high-functioning autism or Asperger syndrome then it is worth checking what criteria the diagnostician had been using.
