How people think about and diagnose autism has changed substantially since the diagnosis was first introduced nearly 75 years ago. In 1943, Leo Kanner firstcoined the term ‘infantile autism ‘ to describe children who seemed socially isolated and withdrawn.
The number of reported cases of autism increased dramatically in the 1990s and early 2000s, prompting investigations into several potential reasons: More children may have autism; that is, the true frequency of autism may have increased.
Furthermore, According to the most recent available data, the Northeast region had the highest rate of autism spectrum disorder in the U.S., with around 3 percent.

As for autism, studies demonstrate that behavioral signs can begin to emerge as early as 6 to 12 months. However, most professionals who specialize in diagnosing the disorder won’t attempt to make a definite diagnosis until 18 months.
There is no cure for autism, but early intervention using skills-training and behavior modification can yield excellent results. This type of educational and behavioral treatment tackles autism symptoms — impaired social interaction, communication problems, and repetitive behaviors.
ADHD is not on the autism spectrum, but they have some of the same symptoms. And having one of these conditions increases the chances of having the other. Experts have changed the way they think about how autism and ADHD are related.
Autism Prevalence In 2020, the CDC reported that approximately 1 in 54 children in the U.S. is diagnosed with an autism spectrum disorder (ASD), according to 2016 data.
Autism spectrum disorder has no single known cause. Given the complexity of the disorder, and the fact that symptoms and severity vary, there are probably many causes. Both genetics and environment may play a role. Genetics.
A common question after an autism diagnosis is what is the cause of autism. We know that there’s no one cause of autism. Research suggests that autism develops from a combination of genetic and nongenetic, or environmental, influences. These influences appear to increase the risk that a child will develop autism.
For instance, autism rates are higher among children born to dads older than 50. Genetic mutations in sperm increase as men age. This may help explain the higher risk. Also, women in their forties are slightly more likely to have a child with ASD.
ASD has a tendency to run in families, but the inheritance pattern is usually unknown. People with gene changes associated with ASD generally inherit an increased risk of developing the condition, rather than the condition itself.
Autism is different for everyone Autism is a spectrum. This means everybody with autism is different. Some autistic people need little or no support. Others may need help from a parent or carer every day.
At both ages, those in the autism and disability groups are more likely than the controls to transition quickly from whimpering to intense crying. This suggests that the children have trouble managing their emotions, the researchers say.
High functioning autism describes “mild” autism, or “level 1” on the spectrum. Asperger’s syndrome is often described as high functioning autism. Symptoms are present, but the need for support is minimal.
Patterns of Behavior Repetitive behaviors like hand-flapping, rocking, jumping, or twirling. Constant moving (pacing) and “hyper” behavior. Fixations on certain activities or objects. Specific routines or rituals (and getting upset when a routine is changed, even slightly) Extreme sensitivity to touch, light, and sound.
