Telling if you're on the autism spectrum (ASD) involves noticing persistent difficulties with social communication, repetitive behaviors, and intense special interests, alongside sensory sensitivities (like sounds/lights), literal thinking, and needing strict routines, though only a professional assessment can provide a diagnosis, as these traits can also appear in others but define autism when they significantly impact life and are present from early development.
Main signs of autism
finding it hard to understand what others are thinking or feeling. getting very anxious about social situations. finding it hard to make friends or preferring to be on your own. seeming blunt, rude or not interested in others without meaning to.
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.
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.

Additionally, inherited genetic variations contribute greatly. Research shows that both mothers and fathers can carry autism-related gene variants. Some of these are common variants that increase the risk of autism, while others are rare mutations causing more severe effects.

Changes in the diagnostic criteria and increased screening at wellness visits seem to be the main contributors.
Children with autism may exhibit rigidity, inflexibility and certain types of repetitive behavior such as: Insistence on following a specific routine. Having difficulty accepting changes in the schedule. A strong preoccupation with a particular interest.
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.
In general, people who have an active lifestyle are much more emotionally resilient and focused. There also seems to be some evidence that physical exercise helps people with depression and ADHD, which are commonly co-occurring conditions with autism.
Symptoms of High-Functioning Autism
Difficulty with Social Interaction: Individuals with high-functioning autism may struggle to understand social norms, make eye contact, initiate or maintain conversations, and interpret nonverbal cues such as facial expressions or body language.
Masking is a strategy used by some autistic people, consciously or unconsciously, to appear non-autistic. While this strategy can help them get by at school, work and in social situations, it can have a devastating impact on mental health, sense of self and access to an autism diagnosis.
M-CHAT-R. The Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) is a screening tool that will ask a series of 20 questions about your child's behavior. It's intended for toddlers between 16 and 30 months of age. The results will let you know if a further evaluation may be needed.
In autistic people this can result in a meltdown (the equivalent of the 'fight' response) which is often mistaken for a temper tantrum. Meltdowns can be expressed verbally (eg, shouting, growling, or crying), physically (eg, kicking or flapping) or a mixture of both ways.
Yelling at an autistic child can cause confusion, fear, and emotional distress that may last far longer than you'd expect. Because autistic kids often process language, tone, and emotions differently, loud voices can be overwhelming—sometimes even physically painful.
Interoception and Autism
This means we might have difficulty accurately perceiving our internal body signals, we may over-feel these signals or simply have difficulty differentiating between body signals and emotional signals, for example, struggling to discern if our discomfort is due to hunger or anxiety.
Researchers are not sure what causes autism, but they believe genetic and environmental factors play a role. Risk factors can include having older parents or a sibling with ASD, genetic or chromosomal conditions like Down syndrome or fragile X syndrome, and very low birth weight.

Autistic people may prefer following set routines or rituals (including having or using favourite items), knowing what is going to happen in advance and for rules to be the same for everyone. These characteristics may help you plan and organise and keep calm and happy.
People with ASD often have problems with social communication and interaction, and restricted or repetitive behaviors or interests. People with ASD may also have different ways of learning, moving, or paying attention. It is important to note that some people without ASD might also have some of these symptoms.
