Autism (Autism Spectrum Disorder - ASD) is identified through a multi-step process involving developmental history review, behavioral observation, and standardized assessments by specialists like psychologists, pediatricians, or speech pathologists, focusing on persistent difficulties in social communication/interaction and restricted/repetitive behaviors, with no single medical test available, relying on DSM-5 criteria. Diagnosis involves parent/caregiver interviews, professional observation of play and interaction, questionnaires, and sometimes ruling out other conditions through hearing/vision tests or genetic testing, leading to a diagnosis and a support level.
Diagnostic Interviews
Specialists use standardized assessments during evaluations to help assess autism spectrum disorder in children. The Autism Diagnostic Observation Schedule™ (ADOS™-2) is a standardized assessment of communication, social interaction, play, and restricted and repetitive behaviors in children.
Main signs of autism
finding it hard to make friends or preferring to be on your own. seeming blunt, rude or not interested in others without meaning to. finding it hard to say how you feel. taking things very literally – for example, you may not understand sarcasm or phrases like "break a leg"
The top signs of autism (ASD) center on challenges with social communication and repetitive behaviors, including difficulty with social interaction (like avoiding eye contact or not sharing interests), repetitive movements or speech (like rocking or repeating words), strong adherence to routines, intense focus on specific interests, and sensory sensitivities (unusual reactions to sounds, lights, or textures). These signs can vary greatly, appearing in early childhood or becoming more apparent in adulthood as social demands increase.
For example, a toddler learning a second language might have speech delays that look like a red flag. Or a child with sensory processing challenges might avoid certain sounds or textures, which can mimic autistic traits. However, these signs alone don't confirm autism.
Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
Seven key signs of autism spectrum disorder (ASD) often involve challenges with social communication (like avoiding eye contact, not responding to names), restricted/repetitive behaviors (like repetitive movements or strict routines), sensory sensitivities (unusual reactions to sounds, lights, textures), and difficulties with emotional understanding or verbal expression, though signs vary greatly and appear differently across ages. Key indicators include limited gestures, delayed speech, intense focus on specific objects, difficulty with pretend play, and strong distress when routines change.
The "6-second rule" for autism is a communication strategy where a speaker pauses for about six seconds after asking a question or giving information, giving the autistic person extra time to process it without feeling rushed, which helps reduce anxiety and allows for a more thoughtful response, reducing frustration for both parties. Instead of repeating or rephrasing, which can be confusing, you wait, and if needed, repeat the exact same words after the pause.
Often children show symptoms of autism within the first year of life. A small number of children with the condition appear to develop as expected in the first year. Then between 18 and 24 months of age, they may lose some skills and develop autism symptoms.
Top 10 Calming Strategies for Autism
Autism in young children
avoiding eye contact. not smiling when you smile at them. getting very upset if they do not like a certain taste, smell or sound. repetitive movements, such as flapping their hands, flicking their fingers or rocking their body.
Changes in the diagnostic criteria and increased screening at wellness visits seem to be the main contributors.
Here are some common signs of “mild autism” in adults to look out for:
There is not just one cause of ASD. Many different factors have been identified that may make a child more likely to have ASD, including environmental, biologic, and genetic factors.
Examples of this can include: following set routines and rituals – examples include eating the same meals each day, doing tasks in the same order, using the same items (such as a favourite cup or pen), taking the same route to school or work, children asking the same questions to hear the same answers (for reassurance)
The three main symptom areas for Autism Spectrum Disorder (ASD) are persistent difficulties with social communication and interaction, restricted or repetitive patterns of behavior, interests, or activities, and often, different ways of learning, moving, or paying attention, all of which impact daily functioning. These core characteristics vary greatly but center on social connection challenges, rigid routines or repetitive actions, and sensory sensitivities.
Research tells us that autism tends to run in families, and a meta-analysis of 7 twin studies claim that 60 to 90% of the risk of autism comes from your genome. If you have a child with autism, you are more likely to have another autistic child. Your other family members are also more likely to have a child with ASD.
Physical Symptoms:
A child with mild autism can ultimately lead a very “normal”, productive, and independent life. With early intervention, a child with autism can learn the skills needed for successful navigation in communication and social interaction with peers in school.
When someone is in a state of high anxiety or flooded with sensory input the brain can become overwhelmed and demand a fight, flight, or freeze response from the body. In autistic people this can result in a meltdown (the equivalent of the 'fight' response) which is often mistaken for a temper tantrum.
Chinning is a form of repetitive self-stimulatory behavior (stimming) that you may notice in children or adults with autism. It involves pressing, rubbing, or holding the chin against objects, surfaces, or even hands to gain sensory input or comfort.
find it hard to communicate and interact with other people. find it hard to understand how other people think or feel. find things like bright lights or loud noises overwhelming, stressful or uncomfortable. get anxious or upset about unfamiliar situations and social events.
Diagnosing autism spectrum disorder (ASD) can be difficult because there is no medical test, such as a blood test, to diagnose the disorder. Doctors look at the child's developmental history and behavior to make a diagnosis.
Yes, a child can have autism and still talk normally. Autism Spectrum Disorder (ASD) affects social communication, but not all children with autism have speech delays. Some may develop language skills on time or even earlier than their peers.
