TONI (Test of Nonverbal Intelligence), perhaps the most popular IQ test for ASD, is a unidimensional test, as are the Naglieri Nonverbal Intelligence Index and Raven's Progressive Matrices tests. These tests, however, remain the best way to measure IQ in ASD patients.
From 1966 to 1998, studies found that about only one-fifth of the people with ASD functioned in the "normal range" of intelligence, according to a 1999 review. 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.
If you're looking for an online IQ test for kids, the MentalUP IQ test is one of the best and it is an IQ test for all ages. If you want a more comprehensive IQ test for your children, you can contact a good psychologist or educationalist, in consultation with the child's school, to help you out with it.
The Aspie Quiz is a self-administered questionnaire to measure autistic traits in adults (age 16+) with an IQ in the normal range (IQ >=80). In fact, it measures both autistic and neurotypical traits in five domains: talent, perception, communication, relationship, and social.
Profound autism is defined as having an IQ of less than 50 or being nonverbal or minimally verbal.
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.
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.
Computed tomography (CT) of the head cannot be used either to diagnose or to rule out Asperger syndrome, because no consistent CT findings are evident in people with this condition.
Level 1 Autism Spectrum Disorder (formerly known as Asperger's Syndrome)
While you can test a child's IQ as early as 2 years and 6 months of age, the results may not be accurate and may in fact change with age. The best time to test IQ in children is between ages 5 and 8.
Empirical evidence suggests that especially parental education, parental income, and maternal IQ are important predictors of intelligence. Parental education together with maternal IQ and the child's sex were found to account for 24% of the variance in IQ at age 5 [6].
Increasing IQ Through Early Intervention
This includes speech therapy, occupational therapy, and Applied Behavioural Analysis (ABA). Early Intervention can help teach a child with ASD basic skills such as communication, gross and fine motor skills, and thinking.
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.
If you still hear people use some of the older terms, you'll want to know what they mean: Asperger's syndrome. This is on the milder end of the autism spectrum. A person with Asperger's may be very intelligent and able to handle their daily life.
“High-functioning autism” isn't an official medical term or diagnosis. It's an informal one some people use when they talk about people with an autism spectrum disorder who can speak, read, write, and handle basic life skills like eating and getting dressed. They can live independently.
Brain mapping is an invaluable diagnostic and treatment instrument for a variety of brain-based disorders, including autism. It enables medical professionals to identify the areas of the brain which are dysregulated that are linked to symptoms.
Since there is no physical test to diagnose this complex neurodevelopmental condition, doctors use behavior, history, and parent-reported interviews to diagnose ASD. Research is suggesting that, in future, brain scans may be used to diagnose autism, possibly even before behavioral symptoms become apparent.
Besides such pragmatic concerns, there are theoretical issues that need to be addressed before MRIs can be used to detect autism. 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.
14-Year-Old Nigerian, Joshua Beckford becomes the youngest to study at Oxford University at the age of 6 and graduated at the tender age of 14 from the Department of History and Philosophy, Despite being diagnosed with high-functioning autism, Beckford was reported to be an early starter.
