What is Autism / Autistic Spectrum Disorder (ASD) / Aspergers syndrome / (AS) High Functioning Autism and Pervasive Developmental Disorder (PDD)?

 

There is much confusion around the terms used for the condition of Autism, you may be told that you, your child/young person or adult has Autism, Autistic spectrum disorder, Aspergers syndrome, High functioning Autism and PDD.

All these terms relate to the condition of Autism.

ASD, AS, High functioning Autism and PDD are all a group of disorders with similar features related to the condition of Autism.

 

Autism is a lifelong developmental disorder of the brain. This means that when the brain was maturing pre natal, it did not develop biologically, physiologically or emotionally as normal.

Autism is a consistent pattern of abilities, disabilities and behaviour that affects a personsí ability to understand the world around them as we know it.

         communication

         imagination

         Social interaction

 

Autism/ASD is a lifelong condition, there is no cure

 

How and to what extent each person will be affected by their Autism/ASD is individual to that person, NO two people with Autism/ASD are the same.

Life experiences can influence how much a person with the condition of Autism/ASD can overcome some of these traits/difficulties, but it can also exasperate their condition.

What is Autism disorder?

What they call (Classic) Autism is named after the psychiatrist Leo Kanner who first recognised Autistic disorder as a condition in children, and wrote books on this behaviour in the early 1930ís.

Kannerís Autism is nearly always accompanied by a severe learning disability, which is an academic I.Q. under 70.

Kanner wrote that those with Autism disorder have -

         An inability to relate to people and situations from birth

         An inability or preference not to use language to communicate

         A need for routines

         A fascination with objects, special interests.

 

What is Autistic Spectrum Disorder (ASD) Aspergers syndrome?

Autistic Spectrum Disorder is the term which is used to refer to a range of disorders on the Autistic spectrum called Aspergers Syndrome, pervasive developmental disorder and childhood disintegrative disorder.

Those with Autistic spectrum disorder (ASD) can have a range of intelligential ability ranging from a Mensa I.Q. well above the population average, right through the scale to severe learning disability. 

Those with ASD would ask

  • Why do we not say what we mean and mean what we say?
  • Why do we make small talk about nothing that is important?
  • Why do we tell people that things are nice when theyíre not?

What appears natural to us may mean the opposite to someone with ASD.

 

 Signs of Autistic spectrum disorder

 

       Social impairment and extreme egocentricity

       Speech & Language peculiarities

       Repetitive routines

       Narrow interests/special interests

       Difficulties understanding NON verbal gestures

       Motor clumsiness

 

These identified behaviours can be considered as a signpost to the diagnoses of Autism/ASD.

We must also point out that some children with ASD can hide the above symptoms until they reach post primary school due to the fear of being different.  However parents need not feel they have failed to pick up their childís difficulties because they are so subtle and complex; and  many of us parents have been duped or thought their child was individual, or just a little eccentric.

Itís during the diagnostic process the psychologist will assess the childís or persons social and emotional abilities, their communication skills, the cognitive skills, special interests, and also their movement skills and sensory difficulties.

 

Social and emotional abilities

Individuals with ASD have difficulties in the following areas

 

       A need for routine and structure

       They are resistant to change

       They are inflexible and misunderstand social rules especially when they apply to themselves.

       They have a difficulty coping with social demands and situations (having little understanding of what is expected of them from family, friends and society).

       They have a literal understanding of language and can correct people on their misuse of language.

       They can lack tact

       They can be unable or are naive at finding the appropriate help and understanding

       They have repetitive and ritualistic activities/special interests.

       Suffer from severe anxiety, which can lead to self harm, depression, lack of self worth and lack of acceptance of their difficulties.

       They are very vulnerable to teasing, bullying, and are a target from people who would take advantage.

       They have a poor ability to manage their emotions and lack the ability to understand theirs and otherís emotions.

       They can suffer from frustration at their own difficulties or in explaining those difficulties to others.

       They have an inability to organise themselves; this can be related to cooking, cleaning, course work for school /college etc.

        They lack the ability to problem solve in true life situations.

       They can have poor sleeping routines, poor toileting routines, and poor diets.

This list is not exhaustive and the above is meant only as a guide

 

Cognitive Skills

Those with ASD are gathers of facts and would only read books that are related to their special interests i.e. Star Trek, Dr. Who, dinosaurs etc.

They have exceptional long term memory but poor short term memory abilities.

 

Special Interests

They have obsessive special interests and will collect items related to that special interest, becoming encyclopaedias on that special interest. 

They have difficulty coping with changes to their daily routine which can cause high anxiety.

They can develop routines that must be completed and adhered too or once again can suffer anxiety attacks i.e. washing of hands, wetting of hair, lining up books and or toys.

 

Movement Skills

When walking or running they suffer from an odd gait and would often bump into door frames, radiators, chairs etc. and often have poor hand to eye co ordination i.e. problems with writing and eating. 

 

Sensory Issues

People with Autism/ASD would have great difficulty with all of their senses.

 

Hearing

They can hear every sound within a shopping mall i.e. talking, walking, music, escalators, tills, etc all at the same time causing complete sensory overload.

 

Seeing

They have sensitivity to bright lights, colours, shadows and flashing colours.  In some with the condition the above is fascinating and compulsive to watch, and in others it would cause frustration, anger and anxiety.

 

Taste

The taste and textures of certain foods can cause immediate retching and choking which means they often have a limited diet.  Some are tube fed or will only eat baby food due to their inability to cope with certain types of food. 

 

Touch

There are those with Autism/ ASD who cannot bear to be touched, others like firm touch and some like light touch.  It is extremely important for those working with people with Autism/ASD to ascertain which touch is appropriate to that person, as mistakes can lead to violent reactions.  They can be over or under sensitive to touch.

 

Smell

 The most expensive perfumes can smell like cats urine, as they have an over sensitive sense of smell. 

It is very important that we understand that although people with Autism/ASD experience similar difficulties related to their condition this does not mean that they are not as individual as you and I are; and can differ according to the support they get or have received.

 

What is high functioning Autism?

There is much confusion around this diagnosis as clinically there is very little difference between High functioning Autism and Aspergers syndrome. It is thought that those who are given a diagnosis of High functioning autism have had no difficulties with language delay and have average or above average intelligent /I.Q.ís. Otherwise those diagnosed with high functioning Autism show the triad of impairments/ difficulties with social interaction, communication and imagination, which is explained under the heading of Autistic Spectrum Disorder ASD.

 

What is PDD?

PDD stands for Pervasive Developmental Disorder and is the broader term sometimes used by health care professionals to describe Autism, Autistic spectrum disorder, Aspergers syndrome, high functioning autism.

 

What is PDD-NOS?

PDD-NOS standís for Pervasive Developmental Disorder Not Otherwise Specified.

This term was first used in the early 1980ís for children who show some of the behavioural characteristics of Autism /ASD but do not meet the full clinical criteria for a diagnosis of Autism/ASD.

A child/young person can be given a diagnosis of PDD-NOS but as the child/young person develops they can be re-diagnosed with Autism/ASD.
