Autism is a very complex disorder and takes a lot of time and learning to fully understand. With this post I hope to cover the basics and give a little insight to anyone not familiar with autism. I could talk ad infinitum about it but will try to keep this short yet informative. Instead of writing this post essay style I think it will be more helpful to use sub-headings and try to keep to the facts.
Rain Man
It seems that the word 'autism' has become synonymous with the film 'Rain Man' so this is a good place to start and perhaps dispel some myths! The film is based on the life of a man called Kim Peek (who sadly passed away in 2009). Although the character in the film was portrayed as having autism, Kim Peek himself didn't have autism. He did have a developmental disability but it was due to another brain condition entirely. His exceptional memory and amazing ability with numbers that everyone remembers so clearly from the film were due to the fact that he was a Savant and not because of autism. Savant syndrome is incredibly rare. Not all Savants are on the autism spectrum, but a majority are. It is estimated that at least 30% of people diagnosed with autism have some area of special skill, an area in which their abilities are significantly above the average. However prodigious skills to the level that Peek had, for example, are rare.
Triad of Impairments
Autism can best be described as a condition causing difficulties in communication and social interaction, and inflexibility and repetitiveness in activities and interests. This is known as the Triad of Impairments in autism. These characteristics come in many forms and vary in both degree and expression from person to person with autism but some examples are:-
- absent or unusual eye contact
- unusual or repetitive use of language
- delayed speech development
- inability to initiate conversation or make 'small talk'
- a need for rigid routines
- pre-occupation with one particular interest
The above list really is a very small sample of autistic characteristics but gives an idea of the ways in which autism manifests itself. People with autism may or may not have intellectual disabilities and often have other disorders alongside their autism such as sensory difficulties.
The Autism Spectrum
Autism effects people in different ways and in varying degrees from the relatively mild to the very severe. It is a very individual disorder and whilst there are broad patterns of symptoms and behaviours, no two individuals with the condition are the same. Because of this autism is described as a Spectrum Disorder. There are a number of sub-types of autism on the spectrum including PDD-NOS, classic autism and Asperger syndrome.
Diagnosis
There is no medical test for autism and no simple snappy definition of the disorder. There are lists of autistic symptoms and in order to be diagnosed with an Autism Spectrum Disorder (ASD) an individual must display a certain number of these symptoms and in certain combinations. Normally a diagnosis is only given at all if there is a particular need to have a diagnosis in order to qualify for certain help e.g. if a child needs special educational support. Diagnosis is often a lengthy process involving various observations and assessments and should include more than one type of medical practitioner i.e. a psychologist, a speech and language therapist and so on.
Cause
There is currently no known cause of autism. There is a mass of research being conducted into the disorder and there are a lot of credible theories but as yet no conclusive answers have been found. There is strong evidence for a genetic basis to the disorder, most likely a polygenic one. There are lots of viable neurobiological and cognitive theories as well. My personal belief is that the mystery lies somewhere along the line of a genetic sequencing causing a certain brain hard wiring that leads to a particular cognitive functioning. But that's just my non-professional opinion I must stress!
There is a lot of unhelpful misinformation bandied about suggesting that environmental factors such as the MMR vaccine cause autism. These theories have absolutely no scientific or medical grounding whatsoever.
Cure
There is no 'cure' for autism. There are lots of therapies that are very helpful in alleviating some of the difficulties associated with autism such as speech therapy or social skills training but these things are not cures as such.
The whole notion of 'curing' autism is a sensitive issue in itself. Many people, myself included, find the suggestion that people with autism need to be 'cured' actually quite offensive. As I see it, autism is not a medical condition or an 'error' in brain wiring that needs to be cured. It is a variation in the way an individual typically thinks, behaves and interacts with the world and is no less valid than a neurotypical personality.
If you are interested to read more about this way of thinking it is known as the Neurodiversity Movement.
It is not all Doom and Gloom.
At the extreme end of the spectrum autism can cause an individual to be completely withdrawn from the world, remain mute and be incapable of living an independent life. In terms of the dependence, this usually occurs in cases where a person with autism also has a very low IQ meaning a significant level of mental impairment.
Fortunately, the majority of people on the spectrum are not nearly as severely effected. Autistic people with average (more so with above average) IQ are able to learn tools and techniques which help them to mask or manage their symptoms and function relatively 'normally' within society. For example, autistic people do not necessarily intuitively react to another person's emotions but they are able to observe social norms and rules, learn them and mimic them. Thus they may be able to have a 'normal' conversation with a stranger let's say, but for an autistic person what comes naturally to the rest of us takes a lot of focus and energy because it is a learnt skill rather than an intuitive one.
Another positive are the niche skills that often accompany autism. Autistic people tend to have what is known as 'scattered skills'. This means that their level of skill in one area to another varies wildly. We all have our particular areas of strengths and weaknesses but in autistic people these strengths and weaknesses can be magnified. Thus, they can have retarded ability in one area but genius level ability in another at the same time. It is also possible for an autistic person to have drastically different abilities within the same skill area, for example struggling with basic counting of numbers but able to solve complex algebra.
Increasingly employers are recognising that far from being unemployable, autistic people have some particular niche skills that far exceed the average person's abilities making them an asset in the workplace. Autistic people generally have a keen eye for detail, often at the expense of the bigger picture, which is at complete odds to the neurotypical majority of us who are generally better at seeing the bigger picture but can completely miss a particular detail. Autistic people literally do see things differently to the majority of people and thus have something very valuable to contribute to society. To use a cliche, they are often real 'outside of the box' thinkers.
Autistic people also seem to have a pre-disposition to logical thinking and an inherent ability to recognise patterns and sequences which is why they commonly have particularly strong talents in the fields of maths, physics,computing and engineering.
In Summary
I will stop there! This is by no means everything there is to say about autism, it's causes and characteristics, but I hope that what I have said above is in some way informative. Needless to say, I know a lot more about it and if you have any particular questions please feel free to ask me. Of course if you are really interested to learn about autism in more depth there are plenty of books and websites on the subject that I can point you in the direction of.
