On the Cutting Edge of Autism Treatment
Teaching autistic children how to engage in imaginative play is one of many new techniques in autism treatment.

The Joker has stolen the world's biggest diamond, and it's up to Batman and Robin to get it back. On a video monitor, hands move toy action figures through the paces of the story, as an off-camera voice speaks the dialogue.
John, age 6, watches the monitor with rapt attention. He is autistic, and this is a technique called "video modeling," used by educators at the New England Center for Children (NECC) in Southborough, Mass., where John and some 200 other autistic kids attend school. When the video ends, Jen, his teacher, affectionately ruffles his hair and directs him to a table that holds the same Batman toys seen in the video. He is supposed to play with them in exactly the same way, saying the same lines, as he has just been shown.
Normally developing children play by imagining scenarios and acting them out with toys. Kids with autism do not. They have to be taught how to play this way. The goal is for them to understand the concept well enough to expand on their play, using their own imaginations.
Learning New Behaviors, Changing Harmful Ones
Teaching play with video modeling is something new that the NECC is studying. On the staff working with the kids are not only educators, but also researchers, and they report on what happens at the NECC to the scientific community. Video modeling is just one small part of the NECC's whole approach, called "applied behavioral analysis," widely regarded as the gold standard in autism treatment.
In the simplest terms, applied behavior analysis offers carrots, with no stick. Children are engaged in learning new behaviors and helped to change disruptive or harmful ones, by constant positive reinforcement. The curriculum at the NECC ranges from the most basic language and social skills to academics and vocational training. "We plug them into that wherever they're at," says Rebecca MacDonald, PhD, director of the preschool program, which includes kids aged 3 to 7.
Another new area she is studying is what's called "joint attention," an important early step in relating to others. If you were to turn and look at something, a typical child observing you would probably turn to look at it, too. An autistic child would not notice. "It's one of the hallmarks of autism," MacDonald tells WebMD. "They tend not to care what you are looking at or thinking."
To encourage them to care, she will make something interesting or rewarding happen if the child follows her gaze. For example, she'll activate an electronic toy by remote control if the child looks at it when she does. Improving joint attention behavior won't make all other social skills fall easily into place. Like video modeling, it's just one tool used in the intensive work that the NECC does. Kids who attend the school go for 30 hours a week, all year long.
The earlier this kind of work can begin, the better the outcomes tend to be for autistic children. Autism can usually be diagnosed by 18 months of age, but some scientists hope that in the future, a blood test at birth might detect it.
In May 2005, researchers at the University of California, Davis MIND Institute announced that they had found remarkable differences in blood tests of autistic and nonautistic children. The children had different levels of certain proteins in the blood and more of some kinds of immune cells.
"The idea for early detection is not only that you can intervene early, which is beneficial, but there's the notion that not all children who ultimately have autism are doomed to it at birth," David Amaral, PhD, research director at the MIND Institute, tells WebMD.
Scientists have speculated that maybe something in the environment makes children who are susceptible to autism develop the disorder. If researchers could identify the trigger, avoiding it might prevent autism.
"In some cases the information might allow full-blown prevention, and in other cases more tailored treatment," MIND Institute researcher Blythe Corbett, PhD, tells WebMD.
It's too early, however, to say for sure what the differences seen in the study mean. "We don't know whether our findings indicate a cause or an effect," Amaral says.
It may be that the immune system plays a role in some children's autism, but "there simply is not going to be a single cause," he says. "In fact, we think of autism not as autism, but as autisms."
What's more, the differences may not be specific to autistic children. "You have to show, for example, that it differentiates kids with autism from kids with obsessive-compulsive disorder or attention deficit disorder," says Eric Hollander, MD, director of the Seaver and New York Autism Center of Excellence at the Mount Sinai School of Medicine in New York City.
