Abstract Some children with Autism Spectrum Disorders (ASDs) exhibit low mental age (Low-MA), defined here as cognitive functioning below 12 months.
Children with autism spectrum disorder (ASD) often have developmental delays, meaning they do not to reach all of their social, emotional, communication, cognitive, and physical milestones at the appropriate times.
During late childhood, neurotypical brains continue to grow in size; in adulthood, they begin to shrink. By contrast, the brains of some people with autism start to shrink prematurely, before their mid-20s.
Overall, while there is no set age at which the autistic brain fully develops, it's important to focus on providing support and resources for individuals with autism throughout their lives.
Amaral: The percentage of kids who increased in severity between ages 6-11 was higher than that of other ages. We theorize that could be due to the many increased social demands that may lead people to withdraw, as well as the development of anxiety, which can increase at that age.

When Does Autism Get Easier? A new study found that around 30% of young autistic children have less severe symptoms at age 6 than they did at age 3. Interestingly, some children lose their autism diagnoses entirely.
Autistic brains develop more slowly than healthy brains, UCLA researchers say. Researchers at UCLA have found a possible explanation for why autistic children act and think differently than their peers.
But years later, in 2014, a U.S. study found that almost half of the children with ASD had average or above average intelligence, that is, an IQ score above 85. Less than a third of the children with autism had intellectual disability, and 23% had IQ scores in the "borderline range" from 71 to 85.
However, brain scans using MRI and other methods do indeed help to recognize targets for the treatment of autism and may even help to diagnose autism in the future.
Today, autism is considered a neurological disorder separate from intellectual disabilities. Among the general population, intellectual disability rates run at about 1 percent; among ASD (Autism Spectrum Disorder) patients, the rate is closer to 40 percent according to the Center for Autism Research.
In the autistic brain, the brain reduced connectivity, known as hypoconnectivity, allows weakly connected regions to drift apart, with sulci forming between them.” Research has shown the deeper theses sulcal pits are, the more language production is affected.
Autistic children are often good at learning by heart (rote memory). Many autistic children can remember large chunks of information, like conversations from movies, words to a song, number plates and so on.
Change in severity of autism symptoms and optimal outcome
One key finding was that children's symptom severity can change with age. In fact, children can improve and get better. "We found that nearly 30% of young children have less severe autism symptoms at age 6 than they did at age 3.
Autism doesn't get worse with age, but certain symptoms can become more pronounced and problematic as the child grows older and is more challenged.
Delays meeting certain milestones can also be a sign of autism: 9 months of age: not responding to their name. 9 months of age: not showing facial expressions associated with basic emotions like happy, sad, angry or surprised. 12 months of age: not engaging in simple interactive games like pat-a-cake.
Though autistic people may respond to emotions and social cues differently than neurotypical people, this does not mean they lack empathy. Just like neurotypical people, levels of empathy vary between autistic individuals.
Autistic people scored on average 30%—and in some cases more than 70%—higher on the RSPM than on the WISC-III, an intelligence test for children between the ages of 6 and 16.
Reasoning in people with Autism Spectrum Disorder (ASD) has been characterised as being slower and more effortful than controls. People with ASD show a more circumscribed reasoning bias, and often take longer to make decisions.
At the level of disrupted neurocircuitry, disruption of four social brain regions is hypothesized to largely drive ASD symptomatology, and these social brain regions are the amygdala, orbitofrontal cortex (OFC), temporoparietal cortex (TPC), and insula.
Analytical Thinking: People with an autism spectrum disorder think in a logically consistent way that leads to quick decision making. These thinkers can make decisions without experiencing the framing effect that inhibits most neurotypicals from making decisions without bias.
In severe cases, an autistic child may never learn to speak or make eye contact. But many children with autism and other autism spectrum disorders are able to live relatively normal lives.
Some, usually those with the least severe problems, eventually may lead normal or near-normal lives. Others, however, continue to have difficulty with language or social skills, and the teen years can bring worse behavioral and emotional problems.
