How to Spot Signs of Autism

Written by Lizzie Learn On 29th Sep 2016

ccording to the National Autistic Society, there are about 700,000 people in the UK living with an ASD (autistic spectrum disorder) condition, that is about 1:92 people. There has been a steep rise in the numbers of people diagnosed with ASD over the last twenty years or so, while this may look like there has been an increase in the proportion of people in the population with ASD, most researchers suggest that this is mostly because of better and earlier diagnosis rather than an actual increase in those who live with the condition.

What is Autism?

The term “autism” and its use to describe a neurodevelopmental (to do with the way the brain develops) disorder is well known today, but less than 100 years ago there was little understanding and a confusion about the nature of the condition.  Even the term “Autism” which was derived from the Greek for self, meaning “self-centred” or “self-obsessed” is inaccurate, as was the idea that there was a relationship with a type of childhood schizophrenia or that the child had somehow been the victim of a cold and uncaring mother labelled as “refrigerator mothers”. Following work in the mid-20th century by two doctors, Hans Asperger and Leo Kanner, the former working in Germany and interested in the high functioning condition which now bears his name, the latter working in the United States, a proper scientific investigation of autism began. It is now agreed that while there are several subcategories, the accepted definition of autism is:

“Autism is a lifelong developmental disability that prevents individuals from properly understanding what they see, hear and otherwise sense. This results in problems of social relationships, communication and behaviour.”

It is not an illness and cannot be “cured” or “treated” though some people may take medication for other difficulties which they may have alongside their autism, for example to treat Attention Deficit Hyperactivity Disorder (ADHD). Having other difficulties alongside autism is known as “co-morbidities” and there are many of these.  ASD should not be seen as a condition, but more a part of a person's personality.  Take away their interests, pedantic language and uncomfortable honesty for instance and they would no longer be the people they are. Together with seeing deficits in ASD, it is clear that some characteristics are strengths; being overly analytical can be seen as attention to detail for instance.  It is suggested that some of our greatest scientists, Einstein and Alan Turing amongst them, may have been somewhere on the spectrum.

The Triad – signs of Autism

Kanner and other researchers noted a pattern of difficulties common to all of their patients.  This became known as the “Triad of Impairments”. The term “impairment” is a negative label which suggests that the characteristics are always negative, which they are not. It is important to remember that Autism is a spectrum and at one end are people with severe learning difficulties alongside their autistic traits, at the other end are people who are extremely able and perhaps have the finest minds of their generation, people such as Albert Einstein and Sir Isaac Newton who were both believed to have had behaviours typical of what we now call “Asperger Syndrome”.  The triad involves three areas of difficulty:

• Social Interaction: A person may not be able to read the non-verbal language of those around them, be awkward with physical contact or touch and may not make eye contact and when anxious have tics or twitches. The person may have difficulty with intimate relationships and not understand reciprocity.
• Social Communication: A person may not be good at normal conversational skills and may even bore those around them with special interest and even be judged rude.
• Difficulties with imagination: This can be manifested in a number of ways. It may mean they have limited interests and are often unable to “put themselves in another’s shoes” or have empathy. It may mean that although they have great ability, they may not be able to imagine simple things – tell stories for example.

Not all people who have autism are the same or have the same difficulties.  A common myth is that everyone who has autism has a “special talent”, the so called “autistic savant”, a person trapped within themselves except for an extraordinary ability. Autistic savants are as rare as gifted people in everyday life. These days it is less common to group all people together under the single name “autism” but use the term “autistic spectrum disorder” (shortened to ASD) instead. This better reflects the fact that the condition is a spectrum and has a range of expression in individuals. There are also more males diagnosed with ASD than women.  Some experts attribute this to the genetics of autism, with males being more vulnerable to sex-linked genetic conditions, others suggest that because the condition presents differently in women and they are less likely to “stand out” at school or other social places, there is a general tendency to under-diagnose females with ASD.
