While some autistic people have exceptional cognitive abilities, others may have intellectual disabilities. According to a study published in the Journal of Autism and Developmental Disorders, about 40% of autistic people have an intellectual disability, while the rest have average or above-average intelligence.
Those with Asperger's syndrome, in contrast, must by definition have suffered no cognitive delay during their first 3 years of life. This means that they will usually have at least a “normal” IQ. In some cases, their IQ may be very high, even in the genius range. There are, however, different kinds of smarts.
The absence of intuitive and even obligatory “mentalizing” in autism may also contribute to talent. People with autism may be less subject to herd thinking, and more able to take original perspectives.
Not All Autistics Are Mathematic Savants, But Many Have Above-Average Math Abilities. It turns out that, despite impressions, most ASD patients may not be any better at math than their counterparts at a particular age or developmental stage.
Savant syndrome is a rare, but extraordinary, condition in which persons with serious mental disabilities, including autistic disorder, have some 'island of genius' which stands in marked, incongruous contrast to overall handicap.
About 70% of autistic people have an intellectual disability, which means they have an IQ lower than 70. The remaining 30% have intelligence that ranges from average to gifted. Autism and intelligence are two separate characteristics. A person can be autistic with any level of intelligence.
Some adults with diagnosed autism are moderately to highly successful people. 6 Some are happily married and partnered, and many are fully employed. Some have even become role models for young adults on the spectrum who hope to live full, independent lives.
Though most symptoms of autism are deficits by nature, some people with autism, known as savants, display special abilities as a result of their condition. Savant abilities are not just special; they are extraordinarily special abilities that cannot be duplicated by most other human beings.
Non-autistic people tend to assess concepts before details, also known as top-down thinking. Autistic people take the opposite approach with bottom-up thinking and use details to build concepts. It may take longer to filter out sensory details with this approach, but you're less likely to miss important information.
Autism Prevalence
31% of children with ASD have an intellectual disability (intelligence quotient [IQ] <70), 25% are in the borderline range (IQ 71–85), and 44% have IQ scores in the average to above average range (i.e., IQ >85).
Some people on the autism spectrum may seek social opportunities and may initiate social interactions themselves, others may enjoy social situations and interactions when they are initiated effectively by others.
Up to 90 percent of people with autism are either overly sensitive to sound, sight, taste, smell or touch, or barely notice them at all. Some seek out sensations by, for example, spinning in circles or stroking items with particular textures.
Some people on the spectrum can recall memories from further back. Additionally, memory in people on the spectrum can closely resemble photographic or near photographic levels. Though they may not recollect a name or face, some individuals on the spectrum could surprise you with the small details they can recall.
For instance, autistic people tend to be particularly honest, reliable, and loyal — some of the most important traits for a long-term relationship. You may just need to be more direct when communicating than you are used to and be prepared to give your partner space when they feel overstimulated.
For people on the autism spectrum, the world is a bewildering place. With oversensitive sensory systems, they battle to process the maelstrom of information flowing into their brains. Often the result is sensory overload, leading to signature behaviours such as tantrums, anxiety and social withdrawal.
Social anxiety – or extreme fear of new people, crowds and social situations – is especially common among people with autism. In addition, many people with autism have difficulty controlling anxiety once something triggers it.
Research shows that more than half of all autistic individuals have an above-average IQ, while roughly 16% have an IQ higher than 130. But having high intelligence doesn't mean that autistic individuals don't experience some challenges associated with the diagnosis.
Death. Triplett died of cancer at home on June 15, 2023. He was the longest-living person known to have autism.
Extra high intelligence is somewhat rare in people with autism. Less than 5 percent of persons with autism exhibit the genius-like abilities like Dustin Hoffman portrayed in Rain Man.
