Parents often miss early signs of autism

I got this article from “The Autism News”. I never knew  this information, and honestly my son’s pediatrician never asked me any question about  these signs. Well, he didn’t even believe me when I voiced my concern  about my son’s developmental issues. His usual response was…” he is a boy, and a second child, and his sibling is a constant talker”. These are all true, but there was still a problem.Later, when Amin was diagnosed his pediatrician admitted that after 25 years of practice he learned a very valuable lesson, which he will be passing along to his medical students…”never underestimate the parental concern”.

So please pass it along to everyone you know.

Many May Not Pick Up Subtle Clues of the Condition, New Study Says

By Chris Emery | ABC News

The symptoms of autism tend to emerge in children after six months of age, with a loss of social and communications skills that is more common and more subtle than previously thought, according to a new study that questions previous assumptions about the progression of the condition.

At six months, children with autism spectrum disorder demonstrated behavior similar to other children, gazing at faces, sharing smiles, and vocalizing with similar frequency, researchers reported online in the Journal of the American Academy of Child and Adolescent Psychiatry.

However, autistic children displayed fewer of these behaviors  they got older, and from six months to 18 months the loss of social communication and skills typically became clear.

While doctors typically caught early signs of autism, the declines were more subtle than previously suggested and most parents — 83 percent — did not report regression in the social behaviors and skills.

“These findings lead us to two major conclusions,” Sally Ozonoff of University of California Davis Health System in Sacramento and colleagues wrote.

“First, the behavioral symptoms of autism spectrum disorder appear to emerge over time, beginning in the second half of the first year of life and continuing to develop for several years.

“Second, our most widely used and recommended practice for gathering information about symptom onset, parent-provided developmental history, does not provide a valid assessment of the slow decline in social communication that can be observed prospectively.”

Autism is thought to emerge in two ways: an early onset pattern and a regressive pattern.

A majority of autistic children are thought to experience the early onset pattern, showing clear signs of the disease in the second year of life but in some cases showing signs before the first birthday.

Those with the regressive pattern are thought to develop normally for the first year of life, then begin losing communications and social skills.

However, most previous studies have been retrospective in design, and some children don’t appear to fit either of the typical patterns, bringing into question the validity of this two-pronged model of onset.

More recently, a third category has been suggested, in which children develop normally and then seem to hit a developmental plateau, but not regress.

In an accompanying editorial, Tony Charman of the Institute of Education in London wrote that the design of the new study heralds a new wave of descriptive developmental studies of autism, or features of autism, in infants and toddlers.

“Previously, the only source of information we had about infancy and toddlerhood of children with autism was retrospective reports from parents at the age of diagnosis (often years after the onset),” he wrote.

“Parental report of early history and development still is an important component of the autism diagnostic evaluation. However, the retrospective parental informant biases, particularly through the lens of autism, might lead both to over- and underestimation of atypical features.”

Ozonoff and colleagues conducted a study that compared 25 high-risk infants later diagnosed with an autism spectrum disorder with 25 gender-matched, low-risk children later determined to have typical development.

The children were recruited for the study at University of California Davis and University of California Los Angeles. The high-risk children were identified based on having a sibling who had already developed autism.

The children were evaluated at 6, 12, 18, 24 and 36 months of age for frequencies of gaze to faces, social smiles, and directed vocalizations, which were coded from video and rated by examiners.

“The results of the current prospective study suggest that the traditionally defined categories of early onset and regressive autism do not portray accurately how symptoms emerge, nor does the newer-onset category involving a developmental plateau,” the authors wrote.

They found that specific social communicative behaviors clearly decreased, rather than failing to progress, as previously thought, with losses especially dramatic between 6 and 18 months.

They concluded that this suggests onset of autism spectrum disorder, marked by loss of social communication behaviors, occurs much more often than has been recognized using parent report methods.

However, rather than the rapid and marked losses typically reported, they saw relatively subtle and gradual declines, which were often preceded by earlier parental concerns and often followed by failures to progress in other areas.

“We urge professionals to refer to intervention any infant or toddler who displays a sustained reduction in social responsivity over time,” they wrote.

“Given the gradual course of symptom emergence and the paucity of diagnostic tools for infants and toddlers with suspected autism, the diagnostic process can be quite protracted and intervention may be needlessly delayed.”

  1. There is obviously a lot to learn about this. There were some pretty good points.
