People with autism do not universally eat less; their eating patterns are highly varied and can include limited food intake, selective eating, or even overeating. Difficulties often stem from sensory sensitivities, a need for routine, or co-occurring conditions, rather than a single cause.
Common signs of autism in adults include:
Furthermore, individuals with Autism generally succumb to health complications approximately 15 to 20 years earlier than the general population. Longitudinal studies that followed people with Autism for over 20 years found that the average life expectancy ranges between 39 years and 58 years.
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.
Stigmatising attitudes and a lack of understanding from non-autistic people can make life difficult for autistic people. This can affect their careers, social lives and interactions with health professionals, which can have devastating consequences.
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.
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.
Understanding the 6 stages of an autism meltdown can help parents, caregivers, and educators respond with empathy and support.
Changes in the diagnostic criteria and increased screening at wellness visits seem to be the main contributors.
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.
The longest living autistic person known is Donald Gray Triplett, famously known as “Case 1,” who was the first person ever diagnosed with autism. He lived until 89 years old, passing away in 2023.

Top 10 Calming Strategies for Autism
The different types of autism include autism spectrum disorder (ASD), autistic disorder (classic autism), Asperger's syndrome, pervasive developmental disorder not otherwise specified (PDD-NOS), childhood disintegrative disorder (CDD), and Rett syndrome.
High-masking autistic individuals often utilize a intensely analytical process known as "deep compensation" to achieve effective Theory of Mind (the capacity to understand other people by ascribing mental states to them, including the knowledge that others' beliefs, desires, intentions, emotions, and thoughts may be ...
Social situations (for example social anxiety or misunderstandings) Sensory overload (for example to much noise, light, itchy clothes) Experiencing changes and unpredictable things. Basic Needs (for example overtired, hungry, thirsty, in pain)
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.
5 common signs of autism in adults
Because autism spectrum disorder can't be cured, many parents seek alternative or complementary therapies. But there's little or no research on these therapies to show whether they're helpful. And some alternative treatments could be dangerous.

Symptoms of High-Functioning Autism
They may also have a tendency to speak in a formal or monotone manner. Restricted Interests and Repetitive Behaviors: Like other individuals on the autism spectrum, those with high-functioning autism may engage in repetitive behaviors or have intense interests in specific topics.
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.
