The latest research on autism. What surprised scientists?

One assumption about autism spectrum disorder is that it coincides with intellectual disability. This claim is supported by research indicating that up to 75% of children with autism also have some degree of intellectual disability. Our results show that this assumption is incorrect. Among the autistic children we studied, two out of three children did not have an intellectual disability
says the lead author of the study, Dr. Josephine Shenouda.

Using medical data for residents of the New York and New Jersey metropolitan area (2000-2016), researchers identified 4,661 8-year-old children on the autism spectrum, of whom 1,505 (or 32.3 percent) had an intellectual disability, and 2,764 (59.3 percent) did not.

Further analysis showed that rates of autism Comorbidity with intellectual disability doubled over the period under review (from 2.9 per 1,000 to 7.3 per 1,000), while rates of this disorder without associated intellectual disability increased five-fold (from 3.8 per 1,000 to 18.9 per 1,000).

Dr. Shenouda says more research is needed to explain this significant increase and pinpoint its causes, but it can already be argued that increased public awareness and more diagnostic testing are playing a role.

And while both of those things may be relevant, the fact that we saw a 500 percent increase in autism among children without any intellectual disability—children we know so easily evade screening—suggests that some other factor is at play as well. This growth.

Scientists are searching for the cause of autism

Researchers at Rutgers have also shown that injury Autism spectrum disorders It is associated with ethnic origin and socioeconomic status. Black children without intellectual disabilities were 30% more likely to be diagnosed with autism. Younger than the white children, A.J probability of diagnosis Among minors living in the most affluent neighbourhoods, it was up to 80 percent higher compared to children from – as defined in the study – from neglected areas.

In the final phase of their study, scientists from Dr. Shenouda’s team worked to estimate the cause of detection rates in some populations Autism spectrum disorders It is clearly underestimated.

Identifying the source of these significant differences will help close the gaps in identification and assistance of children with autism in low-income settings. Given that a large group of people with autism coexist with borderline personality disorder or reduced intellectual ability, great emphasis needs to be placed on early screening, early recognition, and early intervention. Since improvement in intellectual functioning is proportional to the intensity of intervention at an early age, universal screening is essential, especially in disadvantaged communities.
