Autistic children struggle with many obstacles, including learning to speak. And, experts have noted, if these children learn verbal skills by age five, they tend to become happier and higher-functioning adults than do their nonverbal peers. Thirty years ago, psychiatrists expected only half of all autistic children would gain speaking abilities. Recent studies, however, indicate that as many as 80 percent of children with autism can learn to talk. One such study in 2006 showed that toddlers who received intensive therapy aimed at developing foundational oral language skills made significant gains in their ability to communicate verbally. Now researchers have followed up with a number of those kids and found that most of them continued to reap the benefits of that therapy years after it had ended.

Several early behaviors build a foundation for language. These abilities have also been linked to whether a child can anticipate another person's mental state and use that understanding to explain and predict behavior. Developing this "theory of mind" may be a central difficulty for children with autism. Kasari's team targeted two of the early behaviors in their work: The first is the ability to engage in symbolic play, in which one object represents another—a child pretending a doll is his parent, for instance. The second is joint attention, wherein a child divides focus between an object and another person. This behavior can be thought of as "sharing looks." For example, when a child points to show a playmate a toy train, she looks at the moving train and checks to see if her playmate is engaged.

In the initial study, Connie Kasari of the University of California, Los Angeles, and her colleagues evaluated 58 children between three and four years old in a randomized controlled study. The children played with trained graduate students for 30 minutes each day over a period of five to six weeks. The time-intensive interventions focused on either symbolic play or joint attention. A third group, serving as a control, participated in playtime but was not directed to complete tasks and goals.

Independent clinical testers assessed the children before and after the intervention. They measured language and cognitive skills with standard tests, evaluated play level and diversity, and interaction with a caregiver. The initial study, published in 2006, showed that the joint-attention group was better at showing and pointing behavior whereas the symbolic play group showed more symbolic behavior, both in terms of play level and diversity. Twelve months after the therapy period, Kasari's group assessed the kids' language skills. On a standard language test, the two intervention groups showed spoken language improvement that corresponded to 15 to 17 months of development; the control group had only made a nine-month gain during the same period. Younger children and children at the lowest language levels prior to the intervention made the largest improvements. Kasari was initially surprised the groups showed such progress. The most important aspect of both interventions, she says, was "engaging the child for periods of time with a social partner."

In the new study, Kasari's team revisited 40 of the children five years later. The researchers found that 80 percent of them, who were by then eight to nine years old, still had "useful, functional spoken language." A small number of children remained nonverbal, which Kasari says is typical for studies of children with autism. Some children do not seem to be able to learn useful language by age five, but studies suggest it is possible to acquire language later. The new studies show a method for teaching preschool-aged children basic skills that will help them develop language by five and continue to make improvements years later. The researchers detail their findings in the May issue of the Journal of the American Academy of Child and Adolescent Psychiatry.

   While it's important to do everything to help children with autism reach their full potential, we need to ask why so many children have problems with communication and social interaction. We have an autism rate of one in every 88 children, one in every 54 boys and no official knows why. There's nothing a mainstream doctor can tell a new mother so she can make sure her healthy baby doesn't also end up on the autism spectrum. And doctors can't explain why children who were developing normally suddenly and dramatically lose learned skills, stop talking and regress into autism.
   
   Thirty years ago, autism was rare. Today, we have an epidemic of affected children everywhere. We need to address why this is happening to our children.

   Rapid Human Evolution. It really is that simple. Thirty years ago the world was a very different place. Our human ability is to adapt. (The Cave Men of 50,000 years ago were not so different from us in there physiology. Socially and in there psychology the differences are massive. However, if you were to raise a 50,000 year old human baby in today's world there would be no discernible difference between it and us) In the past 30 years there has been numerous evolutionary leaps that mankind has taken, Thus the Human is adapting in various and complicated ways. Some of these adaptions are beneficial some not so much. For someone to understand what is happening they would first have to 'Understand what is happening'. Unfortunately the Humans of Yesterday may not be able to understand the Humans of today much less the Human of tomorrow.

   For anyone that can't access the paper, here are a few more details:
   
   Children were tested on the Expressive Vocabulary Test which I think at this level mainly involves naming pictures.
   
   Eight of the children were off the bottom of the scale.
   
   For the remaining 32 children, those who'd received one of the two interventions (joint attention or symbolic play) scored higher than those who hadn't received intervention. However, it made little difference which of the two interventions they received. The main limitation is that there were only 8 kids in this analysis in the no treatment group.

   There is not a soul on this Earth that will convince me otherwise. VACCINES are the cause of Autism. As a parent of a child with Autism, I blame Big Pharma as well as the doctors for allowing this to happen. The doctor can inform the mothers that they have a right to refuse the vaccines instead of forcing them down their throats and making them feel like a bad parent if they don't get them. When will people wake up and realize that vaccines are just a big money racket and it is at the expense of our children. VACCINES CAUSE AUTISM PERIOD!
