Autism Spectrum Disorder (ASD), frequently referred to as autism, is a complex neurological and developmental condition that starts early in childhood and continues throughout a person's life. Autism affects an individual's ability to communicate and interact with others.
Autism is defined by a certain set of behaviours and is a "spectrum condition" that affects individuals differently and to varying degrees. Some people with autism can live entirely independently while others may need substantial support to carry out basic activities.
Autism is primarily characterised by challenges with social skills, repetitive behaviours, speech, and nonverbal communication. To clear the air surrounding autism, three major categories of autism-related symptoms can be highlighted:
For instance, a child with autism might have difficulty maintaining eye contact, resist physical contact, and have trouble understanding others' emotions. They may stick to specific routines and become highly upset with any change, no matter how minor.
Despite the common misconception, no single “look” characterises autistic people. As with any large group of individuals, autistic people possess a variety of characteristics and behaviours. One can't identify a person with autism based on physical features.
The primary causes of autism remain uncertain, but research suggests that autism results from an interplay of genetic and environmental influences.
Autism has a strong genetic basis, although the genetics of autism are complex and typically it is unclear which genes are responsible. There are several genes that have been identified that are associated with autism, but considerable research is ongoing.
In genetic terms, autism is considered to be a complex disorder, meaning it's influenced by many different genes and their interactions with environmental factors.
The environmental factors are any non-genetic influence that significantly raises the risk of the individual developing autism. These factors include parental age at the time of conception, maternal nutrition, and exposure to certain medications or infections during pregnancy among many others.
These factors, while considered 'environmental', don't diminish the role of genetics, which remains the primary influence, detailing that autism is a complex disease influenced by various components.
Knowing the indicators of autism can be instrumental in spotting it early in a child's life, enabling appropriate interventions to be put in place sooner. The signs of autism tend to appear between 12 and 24 months of age, but they can be seen as early as 6 months. Keep in mind, early signs can vary a lot, and they can be subtle. By adulthood, many symptoms become more consistent, while others may diminish or even disappear.
Autism presents itself through a spectrum of symptoms. Here's an overview of common symptoms that might be seen in children who have autism.
Early detection refers to spotting signs of autism at a young age, ideally before the age of two. Through early detection, a child can begin therapy earlier, often leading to better results.
For example, a 5-year old child with autism might become thoroughly engrossed in a single activity, like lining up toys in a certain way. It may be so absorbing that the child might become unhappy if their pattern is disrupted.
Autism can cause significant social, communication, and behavioural challenges. From a social interaction standpoint, a child or adult with autism might:
Communication can be a significant challenge for people with autism. Remember though, every person with autism is different. Some might be able to speak well while others might not speak at all. Common communicational challenges include:
It's quite possible for adults to be diagnosed with autism later in life. Some might have been diagnosed as children but slipped through the nets of detection. Others might have received diagnoses other than autism.
Autism symptoms in adults can vary significantly based on the severity of the disorder, but they generally revolve around repetitive behaviour, communication difficulty, and problems with social interactions. For example:
These symptoms can coexist with other challenges or conditions, making it essential for anyone suspecting they might be autistic to seek professional diagnosis.
Autism Spectrum Disorder, abbreviated as ASD, embodies a comprehensive group of neural development disorders which are characterised by varying degrees of deficits in social interactions, communication skills, and a tendency towards repetitive behaviour patterns.
Autism Spectrum Disorder, as the term denotes, is not a single disorder but encompasses a wide spectrum of closely related disorders sharing core symptoms. Every individual with ASD may present differently, with a unique combination of symptoms of varying degrees of severity.
ASD is distinguished by persistent deficiencies in communication and social interaction across multiple contexts, as evaluated by clinician judgement and parent report.
For instance, an individual with ASD might struggle with social reciprocation and nonverbal communication, have difficulties developing and maintaining relationships or display repetitive patterns of behaviour, interests, or activities.
Often, the terms autism and ASD are used interchangeably. However, there are subtle, albeit significant, differences. Put simply, autism is one of the numerous subtypes within the autism spectrum disorders.
Autism is at one end of the spectrum and is typically associated with severe forms of social communication challenges, restricted interests, and repetitive behaviours. The spectrum also includes conditions formerly perceived as separate disorders, like Asperger syndrome and pervasive developmental disorder-not otherwise specified (PDD-NOS).
It's crucial to remember that some individuals may have mild symptoms of ASD, while others may have more severe symptoms. But real distinction lies in the symptom severity, their manifestation, and the child's developmental level and chronological age, which influences whether symptoms are presented and detected.
Identifying ASD involves a two-step process. The first involves general developmental screening during well-child check-ups and the second involves additional evaluation by a team of doctors and other health professionals who are experienced in diagnosing ASD.
The Diagnostic and Statistical Manual of Mental Disorders, also known as the DSM-5, details the specific criteria for an autism diagnosis. There are two main categories for diagnosis:
Professionals making the diagnosis are also required to note whether the person has accompanying intellectual impairment, language impairment, or a known medical or genetic condition.
The second step for autism diagnosis is a comprehensive evaluation. This review may include observing the child's behavior and development, conducting an interview with the parents, and may also include a hearing and vision screening, genetic testing, neurological testing, and other medical testing.
Among the most commonly employed evaluation tools are:
Each of these tools works in a different way and is designed to measure various aspects associated with the condition like communication, social interaction and highly structured behavioural patterns, providing a thorough assessment for diagnosis.
These evaluation tools for autism are focused mainly on observing the behaviours and symptoms that interfere with an individual’s ability to function effectively in different areas of life.
