Autism Spectrum Disorder early signs & symptoms in children
Reading Time: 3 minutes

Autism is officially classified as Autism Spectrum Disorder (ASD), and includes what was previously known as Asperger’s Disorder. The use of the word “spectrum” indicates that people with ASD can have a range of symptoms and behaviours, and some may need more support than others.

What is the difference between high & low functioning Autism?

Often, the labels “high functioning” and “low functioning” are used to describe the way people with ASD present, and to explain the kinds of support they require. “High functioning” individuals have fewer support needs, and may be more independent than those who are classified as “low functioning.” Some individuals with ASD have cognitive delays and learning difficulties, while others may function at a normal or even heightened cognitive level (previously known as Asperger’s Disorder).

ASD is a developmental disorder, which means that it begins in childhood and occurs across all stages of development into adulthood. Approximately 1-2 in every 100 people have ASD, with varying support needs. This makes ASD one of the most common developmental disorders in the world.

What causes Autism Spectrum Disorder?

Despite the fact that 2% of the world’s population is on the spectrum, scientists and doctors still know very little about what causes ASD. It seems to be that there is a genetic component to the disorder, and ASD does seem to run in families. However more research is needed to understand exactly what the genetic link is. Furthermore, risk factors for autism include older parental age and parental substance abuse. Many people may have heard the claim that vaccines cause autism, however there is no scientific evidence to support this idea.

What are the early signs and symptoms of Autism Spectrum Disorder in children?

Although we don’t know exactly what causes ASD, we do know what early signs and symptoms to look out for that may indicate ASD in children, and spreading awareness of these signs can assist in earlier identification and intervention:

Difficulty in forming and maintaining social relationships

Individuals with ASD often struggle to understand the social norms that others live by. This makes it difficult to maintain friendships and communicate with peer groups.

Difficulty in understanding nonverbal communication

Maintaining eye contact, reading facial expressions and gestures, and subtle changes in voice (such as sarcasm) are difficult for individuals with ASD.

Repetitive behaviours

This is also known as “self-stimming” (self-stimulation). This includes repeated motor movements, repeated use of an object or toy, or repeated speech sounds.

Insistence on sameness

Individuals with ASD often adhere to a strict routine, and have important rituals that they must follow.

Sensitivity to sensory inputs

Sounds, lights and textures may feel overwhelming, or the individual may be less sensitive to sensory inputs and need heightened stimulation to get a response.

Concrete thinking

This can cause difficulty in engaging with symbolic or imaginative play.

Fixated interests

Individuals often have interests which seem unusual to others. These “obsessions” may help the individual in soothing their own anxieties.

Difficulty with language

A failure to develop language can be an early sign of ASD.

Anxiety and depression

People with ASD are more likely to suffer from anxiety or depression in their lifetime than their neurotypical peers.

What are the signs of Autism Spectrum Disorder in adults?

The symptoms of ASD are seen across developmental stages, but may present differently for adults and children. Adults may have learned coping strategies to assist them with social communication and sensory overload. These social and sensory difficulties may also cause children difficulties in a mainstream school environment, and may cause adults difficulty at work. Additionally, due to a lack of understanding of what ASD is, often families are treated with stigma, and individuals with ASD are isolated.

The link between ARVs and child development

Additionally, considering the high rates of HIV/AIDS in South Africa, health practitioners as well as teachers and childcare workers should be aware of the effects of HIV/AIDS and ARV’s on children’s development.

Developmental delays may result from HIV/AIDS and related treatment, or may be a result of a developmental disorder such as ASD. This means that it can be difficult to diagnose ASD, and highlights the importance of being aware of a child’s context. However, early identification and intervention of ASD is crucial in assisting a child to develop to their full potential, and practitioners should not overlook the possibility of ASD even when other factors are present.

Finally, it is important to remember that each person with ASD is unique: each individual has their own place on a complex spectrum. This means that what is difficult for one individual with ASD may be easy for another.

Dr. Stephen Shore, who is on the autism spectrum himself, has said: “If you’ve met one individual with autism, you’ve met one individual with autism.” We should be sensitive to each individual’s unique strengths and weaknesses, and approach individuals with ASD with empathy and kindness.
