Several genes seem to be involved in autism spectrum disorder. For some children, autism spectrum disorder can be related to a genetic condition, such as Rett syndrome or fragile X syndrome. For other children, genetic changes, also known as mutations, may raise the risk of autism spectrum disorder.
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.
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.
What are the treatments for 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.
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.
Changes in the diagnostic criteria and increased screening at wellness visits seem to be the main contributors.
Understanding the 6 stages of an autism meltdown can help parents, caregivers, and educators respond with empathy and support.
A healthy diet rich in folic acid, omega-3 fatty acids, and iron supports brain development and lowers the risk of developmental disorders like autism. Folic acid supplements before and during pregnancy can significantly reduce the risk of autism.
Top 10 Calming Strategies for Autism
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.
It's something you're born with. Signs of autism might be noticed when you're very young, or not until you're older. If you're autistic, you're autistic your whole life.
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.
What NOT to Say to Someone with Autism
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.
However, autistic meltdowns are not age-related and they may happen at any age. Many autistic adults, especially the higher functioning ones, may learn some strategies to prevent meltdowns and cope with them.
Q: Is autism genetic from mother or father? A: Autism can be inherited from either parent, as it often involves a combination of genetic factors. No single parent is solely responsible, and it typically results from a complex interaction of genes from both sides.
Prevalence of Autism Spectrum Disorder
China currently has the highest rate of autism, with a prevalence of 2.6%, followed by South Korea, the United States, and others. In the United States, approximately 1 in 59 children are diagnosed with ASD, making it one of the countries with higher rates of autism [3].
Depending on your child's needs, speech therapy to make communication skills better, occupational therapy to teach activities of daily living, and physical therapy to make movement and balance better may help. A psychologist can recommend ways to manage problem behavior. Medicines.
Experts haven't found a single cause of autism. It's likely a combination of genetics and certain things related to pregnancy, labor and delivery. You might see these things described as “environmental factors” or “prenatal events.” These factors all interact to lead to the brain differences we see in autism.
Yes, many children with autism form deep attachments to their parents, though they might not always express them in ways that are easily recognized.
While autism is typically not diagnosed before the age of 2 (and often much later), it can sometimes be detected earlier. A 2022 study found that a routine second-trimester ultrasound could detect early signs of autism during pregnancy,18 including anomalies in the heart, head, and kidneys.
