Autism seems more common now primarily due to significantly improved awareness, broader diagnostic criteria (including previously overlooked milder cases and conditions like Asperger's), better screening tools leading to earlier detection, and reduced stigma. While some genetic or environmental factors might play a small role, the main driver is better identification of individuals who always had autism but weren't diagnosed, especially girls and adults, and increased parental/professional recognition of diverse presentations.
The first is the broadened definition of Autism Spectrum Disorder, which means that more people are meeting this definition now than previously. Second, there have been many widely successful public health programs that increased screening at wellness visits for children ages 18–24 months to look for signs of 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.
Why is autism on the rise? Autism prevalence has risen due to increased awareness of autism, broader diagnostic criteria for autism, improved screening tools and standardized screening processes. These factors have led to earlier detection and more diagnoses.
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.
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.
Donald Triplett, autism's 'Case 1,' dies at 89. Triplett gained media attention for his autism later in life, and he became the face of the effort to research the lives of older adults with autism.
While diagnostic expansion is evident — and may result in overdiagnosis in certain contexts — a significant number of individuals remain underdiagnosed, particularly among groups such as girls, individuals with typical intellectual functioning, racialized populations, or those from lower socioeconomic backgrounds.
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.
But Kennedy's greatest breach with the scientific consensus was likely his insistence that autism is an “epidemic” that must be caused by an environmental exposure that has been introduced within the past several decades. In fact, researchers say, autism is between 60 and 90 percent heritable.
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.
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.
Here are three key aspects to consider in reducing autism risk: prenatal care and nutrition, genetic counseling and testing, and avoiding environmental toxins.
Adults may pursue a diagnosis for a variety of reasons, including curiosity, self-understanding, or long-standing questions about how they relate to the world. And unlike in the past, he says, the idea of an autism diagnosis no longer feels as isolating. “Ten years ago, people were hesitant to seek a diagnosis.
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.
What NOT to Say to Someone with Autism
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. Diagnosing ASD involves several steps.
Pregnancy spacing may affect odds of ASD. Mothers of children with autism spectrum disorders (ASD) may reduce their odds of having another child with ASD if they time a second pregnancy to occur 2.5 to 3 years after the birth of the child with ASD, according to a new study.
According to the latest research, folic acid in the form of a supplement can help develop speech skills and improve brain function. ASD is a condition that arises from disruptions in the brain's cellular structure, leading to difficulties with speech and learning.
Conditions That Can Be Mistaken for Autism. These include: Speech delays, hearing problems, or other developmental delays: Developmental delays are when your child doesn't do things doctors expect kids their age to be able to do. These can include language, speech, or hearing problems.
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.
The Unmasking Effect of ADHD Medication
ADHD medication can strip away the ADHD shield which may have been hiding Autistic traits. This often leads to a deeper exploration of neurodivergence, helping women identify and understand themselves more holistically.
Clinicians who encountered autism in the 1950s and 1960s called it by many names. Among them were Kanner's syndrome (named after Leo Kanner), early infantile autism, hyperkinetic disease, and Heller's disease (based on 1908 description by Austrian educator Theodor Heller), also known as dementia infantilis.
ASD Level 1: Requiring Support
Level 1 is the mildest, or “highest functioning” form of autism, which includes those who would have previously been diagnosed with Asperger's syndrome. Individuals with ASD level 1 may have difficulty understanding social cues and may struggle to form and maintain personal relationships.
