Your guide to autism: Understanding ASD from diagnosis to daily life
Understanding autism spectrum disorder (ASD) can feel overwhelming, whether you're seeking answers for yourself, a loved one, or simply wanting to learn more about this neurodevelopmental condition. This comprehensive guide addresses the most common questions about autism, offering clear insights and practical information to help you navigate this journey with confidence and understanding.
Autism affects millions of people worldwide, yet many misconceptions persist. By exploring the facts, symptoms, and support options available, we can build a more informed and compassionate understanding of what it means to live with autism.
What is autism and ASD?
Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterised by differences in social communication, interaction, and behaviour. The term "spectrum" reflects the wide range of experiences and abilities that individuals with autism possess.
What does ASD stand for?
ASD stands for Autism Spectrum Disorder. This terminology replaced earlier terms like "Asperger's syndrome" and "pervasive developmental disorder" when the diagnostic criteria were updated in 2013. The spectrum approach recognises that autism presents differently in each person, with varying strengths and challenges.
Understanding autism symptoms
Autism symptoms typically fall into two main categories:
Social communication and interaction differences:
Difficulty with back-and-forth conversation
Challenges with nonverbal communication like eye contact and facial expressions
Trouble developing and maintaining relationships appropriate to developmental level
Restricted and repetitive patterns of behaviour:
Repetitive motor movements or speech
Strong preference for routines and rituals
Highly focused interests
Sensory sensitivities (over- or under-responsiveness to sensory input)
How common is Autism?
Current research suggests that approximately 1 in 44 children are diagnosed with autism spectrum disorder. The condition affects people of all ethnic and socioeconomic backgrounds, though it's diagnosed about four times more often in boys than girls.
These numbers have increased significantly over the past decades, largely due to improved awareness, better diagnostic tools, and expanded diagnostic criteria rather than an actual increase in prevalence.
Understanding Autism levels
The autism spectrum includes three levels of support needs, helping to describe the amount of assistance someone might require in their daily life.
What is level 1 Autism?
Level 1 autism, previously known as "high-functioning autism" or Asperger's syndrome, describes individuals who require minimal support. People with level 1 autism may:
Have difficulty initiating social interactions
Struggle with organisation and planning
Experience challenges with transitions
Appear to have fewer obvious autism traits
What is level 2 Autism?
Level 2 autism indicates a need for substantial support. Individuals at this level may:
Have more noticeable difficulties with verbal and nonverbal communication
Show limited initiation of social interactions
Experience distress when routines are disrupted
Display repetitive behaviours that interfere with daily functioning
What is level 3 Autism?
Level 3 autism requires very substantial support. People at this level may:
Have severe difficulties with verbal and nonverbal communication
Show very limited initiation of social interactions
Have extreme difficulty coping with change
Display repetitive behaviours that significantly limit functioning
What causes Autism?
Understanding the root causes
It is currently understood in the mainstream medical field that Autism is caused by a complex interplay of genetic and environmental factors. Research consistently shows that autism is primarily genetic, with multiple genes contributing to its development. There's no single "autism gene," but rather hundreds of genetic variations that can increase autism risk.
What are the 3 main causes of autism?
While autism's exact causes remain under investigation, research points to three main contributing factors:
Genetic factors: Family studies show that autism runs in families, with siblings of autistic individuals having a higher likelihood of also being autistic.
Environmental factors during pregnancy: Certain prenatal factors, such as advanced parental age, maternal infections during pregnancy, or exposure to specific medications, may slightly increase autism risk.
Brain development differences: Neurological research shows that autistic brains develop differently, particularly in areas responsible for social communication and sensory processing.
ASD and immunisation: Extensive research has been conducted to examine the potential link between autism spectrum disorder (ASD) and immunisation. Numerous studies across various countries and populations have mixed results. The mainstream view is that there is "no credible evidence" to support a connection between routine childhood vaccinations and the development of autism. Parents are recommended to do their own research around immunications.
Which parent carries the autism gene?
Research suggests that both mothers and fathers can pass on genetic variations that contribute to autism risk. However, the inheritance pattern is complex and involves multiple genes rather than a single gene from one parent.
What causes autism during pregnancy?
Several prenatal factors may influence autism risk:
Maternal infections during pregnancy
Certain medications taken during pregnancy
Complications during birth
Advanced parental age
Nutritional deficiencies
How does sperm health influence autism risk?
The health of a father's sperm can also play a significant role in influencing autism risk. Research has shown that factors such as the age of the father, sperm DNA quality, and lifestyle choices can potentially impact genetic contributions. Advanced paternal age has been associated with a higher likelihood of genetic mutations, which may increase the risk of autism in offspring. Additionally, negative lifestyle factors such as smoking, excessive alcohol consumption, and exposure to environmental toxins can affect sperm quality and DNA integrity. These findings highlight the importance of maintaining overall health and well-being to support reproductive outcomes.
Getting an Autism diagnosis
How to know if you have autism
Recognising autism symptoms in yourself or others can be the first step toward understanding and support. Common signs include:
Difficulty with social interactions and communication
Preference for routines and predictability
Intense interests in specific topics
Sensory sensitivities
Repetitive behaviours or movements
Who can diagnose ASD?
In Australia, autism diagnoses are typically made by qualified professionals including:
Paediatricians (for children)
Psychiatrists
Psychologists with autism expertise
Multidisciplinary teams in specialist autism centres
Australia follows established guidelines to ensure consistent, accurate, and evidence-based practices for diagnosing and supporting individuals with Autism Spectrum Disorder (ASD). The National Guideline for the Assessment and Diagnosis of Autism Spectrum Disorders in Australia provides a framework for clinicians and families. This guideline emphasises a team-based approach, involving multiple professionals to gather a comprehensive understanding of an individual’s needs. It also recommends considering the individual’s medical history, developmental milestones, and conducting structured observations and assessments. By adhering to these guidelines, families and professionals can work together to achieve more reliable diagnoses and enable access to appropriate interventions and support systems tailored to individual requirements.
How to get an autism diagnosis in Australia
The diagnostic process usually involves:
Initial consultation: Discuss concerns with your GP for a referral
Comprehensive assessment: Detailed evaluation by qualified professionals
Observation and testing: Structured assessments and observation of behaviour
Report and recommendations: Detailed diagnostic report with support recommendations
How early is autism detected?
Autism can sometimes be identified as early as 12-18 months, though diagnosis often occurs between ages 2-4. Early signs include:
Limited eye contact
Delayed speech development
Lack of pointing or gesturing
Repetitive behaviours
Sensory sensitivities
Common questions about Autism
Can you develop autism?
Autism is currently understood as a neurodevelopmental condition present from birth. While symptoms may become more noticeable over time or during periods of stress, autism itself doesn't develop later in life. However, many people receive their first diagnosis in adulthood when they better understand autism or when life demands exceed their coping strategies.
How autism feels from the inside
Living with autism is a unique experience for each person. Many autistic individuals describe:
Feeling overwhelmed by sensory input
Difficulty understanding social cues
Intense focus on interests
Need for predictability and routine
Challenges with emotional regulation
What is sensory autism?
Sensory differences are a core feature of autism. Many autistic people experience:
Hypersensitivity to lights, sounds, textures, or smells
Hyposensitivity (under-responsiveness) to sensory input
Difficulty filtering sensory information
Seeking or avoiding certain sensory experiences
What are T-Rex arms in autism?
"T-Rex arms" refers to a common posture where someone holds their arms close to their body with bent elbows, similar to a T-Rex dinosaur. This posture often occurs when someone feels anxious, overwhelmed, or is trying to regulate sensory input.
What is eye tracking in autism?
Eye tracking refers to differences in how autistic individuals look at and process visual information. Research shows that autistic people may:
Look at different parts of faces or objects
Have difficulty with sustained eye contact
Focus on details rather than the whole picture
Process visual information differently
Autism myths and misconceptions
"Autism isn't real"
This harmful misconception persists despite overwhelming scientific evidence. Autism is a well-documented neurodevelopmental condition recognised by medical professionals worldwide and supported by decades of research.
Can autism be cured?
Autism is not seen as a disease that needs curing. It's understood in the mainstream world as a neurological difference that's part of who someone is.
How is autism "treated"?
Speech and language therapy
Occupational therapy
Psychological support
Social skills training
Sensory integration therapy
Educational support
Behavioural interventions
Supporting people with Autism
What is ABA therapy for autism?
Applied Behaviour Analysis (ABA) is a therapeutic approach that uses behavioural principles to teach skills and reduce challenging behaviours. While ABA can be helpful for some individuals, it's important to ensure that any therapy approach respects the person's dignity and focuses on meaningful goals.
What is a social story for autism?
Social stories are simple, personalised narratives that help explain social situations, expectations, and appropriate responses. They can help autistic individuals understand and navigate social scenarios more effectively.
What triggers autism meltdowns?
Meltdowns are intense responses to overwhelming situations and can be triggered by:
Sensory overload
Unexpected changes
Communication difficulties
Anxiety or stress
Physical discomfort
How to reduce toe walking in autism
Toe walking is common among autistic individuals and can be addressed through:
Physical therapy
Sensory activities
Appropriate footwear
Addressing underlying sensory needs
Professional assessment for any physical causes
How to stop repetitive behaviour in autism
Rather than stopping all repetitive behaviours, focus on:
Understanding the function of the behaviour
Providing appropriate sensory alternatives
Teaching replacement behaviours
Creating structured environments
Addressing underlying needs
Co-occurring conditions
Can you have BPD and autism?
Borderline Personality Disorder (BPD) and autism can co-occur, though they're distinct conditions. Both involve challenges with emotional regulation and relationships, but they have different underlying causes and require different approaches to support.
Can you have DLD and autism?
Developmental Language Disorder (DLD) and autism can occur together. Both conditions affect communication, but DLD specifically impacts language development while autism affects broader social communication and behaviour patterns.
Life with Autism
Why is autism life expectancy lower?
Research suggests that autistic individuals may have shorter life expectancy due to:
Higher rates of co-occurring health conditions
Increased risk of accidents
Mental health challenges
Barriers to healthcare access
Social isolation
However, with appropriate support and understanding, autistic people can live full, meaningful lives.
What causes non-verbal autism?
Non-verbal autism isn't caused by specific factors but rather represents one way autism can present. Some autistic individuals may:
Use alternative communication methods
Have apraxia (difficulty with motor planning for speech)
Experience selective mutism
How can non-verbal autistic individuals communicate?
Although speech may not be their primary mode of communication, non-verbal autistic individuals have various ways to express themselves and interact with others. Some common methods include:
Augmentative and Alternative Communication (AAC) devices: Tools such as speech-generating devices, tablet apps, or communication boards enable individuals to communicate their thoughts and needs effectively.
Sign language: Some non-verbal individuals may use sign language to convey messages, especially if they have the appropriate motor skills.
Gestures and body language: Facial expressions, pointing, or other physical movements can be used to indicate feelings or requests.
Writing or drawing: For those with the ability to write or draw, these can serve as practical means of communication.
It's crucial to create an environment that supports these methods and ensures that individuals feel heard and respected. Providing opportunities to develop and enhance communication skills can significantly improve their quality of life and social connections.
