As a child, I learned how autism turns a world upside down. In our house, it was my little brother who was diagnosed at 3. In the search for a treatment, parents will go to any lengths. I saw that with my parents, and I see it now as a practicing physician. Much has changed in the field of autism, but the need for parents to make decisions in a bewildering terrain has hardly changed at all.
A diagnosis of autism usually rests on three distinctive symptoms: difficulty with social interaction, problems with verbal and nonverbal communication, and repetitive actions or obsessive interests. These behaviors can range from mild to disabling.
Parents may first notice that something is wrong when their child fails to babble or point by age 1 or to speak by 16 months. Some autistic children don’t smile or make eye contact. Others seem to be hearing impaired or do not know how to play with toys. There also are cases in which a child who appears to be making normal developmental progress abruptly loses language or social skills.
Is Autism an Epidemic?
Until the 1940s, there was no autism - in the sense that it was an unrecognized condition. In 1988, when Dustin Hoffman’s Rain Man brought a version of autism to life on film, many of us first heard about it - as an odd, almost-fascinating disorder which was also, apparently, rare.
Fast-forward to today. Autism is front-page news. Celebrities talk about it, Congress ponies up millions for research, and the numbers are startling: One in every 150 American kids has some form of autism, says the Centers for Disease Control and Prevention. The last 15 years in particular have seen diagnoses rates soar. "It is the fastest-growing developmental disability in the U.S.," says Dr. Andrew Zimmerman, director of medical research at the Kennedy Krieger Institute Center for Autism and Related Disorders in Baltimore.
No one really knows why the numbers are so high. But there are many theories. The most commonly accepted one centers on how we define and recognize autism. "There has been an expansion in the criteria," explains Dr. Cecelia McCarton, the director of a school for autistic children in New York City, echoing the majority of mainstream experts.
A broader definition means that there are simply more ways to be considered autistic than in the past. At the same time, parents, teachers and doctors are paying more attention to the symptoms - which tends to lead to higher numbers of diagnoses.
But changes in how children are labeled and diagnosed alone "cannot explain the rise," says Dr. Zimmerman. Other theories rest on maternal, obstetric or environmental factors that perhaps trigger an innate tendency. "Anything from autoimmune disorders to chemicals in the environment may be involved," adds Zimmerman. He notes that researchers have been pursuing all of these theories to varying degrees, "but science has not yet pointed us to any concrete answers." An important study released this month suggests that a genetic flaw that occurs around conception may sharply increase the risk that a child will develop autism.
More than perhaps any brain disorder in history, autism has ignited heated arguments among parents and professionals.
What Is the Best Treatment?
There currently is no single definitive treatment for autism. "One size fits all" does not work. But starting early does. These days, children as young as 1 are being evaluated and treated. "The sooner you start, the better off you are," says Dr. McCarton. Early intervention works, she explains, because of the malleability of the brain in very young children - that is, its ability to grow and develop when stimulated.
Today, most school-based programs rely on behavioral therapy to stimulate development. The treatment aims to reinforce appropriate behaviors while discouraging the inappropriate. Typically, a child is required to perform over and over a task that autism makes difficult - say, buttoning a shirt - with rewards such as stickers or candy for performing the task correctly. This approach, practiced in different variations and sometimes customized to the individual child, helps some autistic children make eye contact, increase spoken vocabulary and master basic life skills.
Lisa Goring of Manhasset, N.Y., got her son Andrew early-intervention services at age 2. "When we started, Andrew threw tantrums that made it impossible for us as a family to go anywhere," recalls Goring. "At first we felt lost. But after we found a program, he learned how to speak. Once he was able to communicate, his world opened up." Andrew made such good progress that he was able to enter mainstream kindergarten. He’s now in sixth grade. Though not at the level of his peers, Andrew functions well with one-on-one support provided by his school district.
While behavioral programs claim a scientific basis, the reality is that it is difficult to test their effectiveness or even to compare one type of behavioral treatment with another. Still, these therapies win general endorsement by most professionals and many public school districts (though insurance companies generally refuse to pay for them).
Do Vaccines Cause Autism?
Most doctors and researchers answer a clear "no" to this question. But the controversy remains alive in the media and among parent-advocacy groups.
Parents in these groups have reported a sudden and dramatic social disconnect - including loss of language - in children who previously seemed to be developing normally. The change occurred soon after the children were given the first dose of the MMR vaccine (to prevent against measles, mumps and rubella), typically at around 12-15 months. These parents adamantly believe that their children’s autism was caused by something in the MMR vaccine or in combination with other vaccines containing the mercury-based preservative thimerosal. They insist that the timing of the onset of autistic symptoms is not a coincidence.
While some physicians and scientists support the vaccine-autism link, the overwhelming majority of medical professionals and mainstream medical organizations maintain that vaccines do not cause autism. This is the position of the Institute of Medicine (IOM), National Academy of Sciences, CDC, American Academy of Pediatrics and NIH. After reviewing the research, the IOM concluded that the evidence "did not support an association between autism and the MMR vaccine."
In fact, even autistic children who never received the MMR vaccine first show symptoms at around the same age as those who are vaccinated.
Is There Hope?
Parents of autistic children should not despair. "Many kids do very well and adapt to their situation," says Dr. Lee Marcus, clinical director of the pioneering TEACCH program in Chapel Hill, N.C. Since the 1960s, the program - now mandated in North Carolina - has been combining behavioral and developmental therapies, with parents as co-therapists. "There can be progress and optimism about the future. Society is more accepting. Many people do a good job teaching kids with autism."
Indeed, the road ahead for people with autism depends on the attitudes of the rest of us and our willingness to create opportunities for jobs, for education and for inclusion. "We know our son will always have challenges," says Lisa Goring, "but we feel very fortunate that we found people who understood how to teach him. He’s different, but his friends absolutely accept him. He has a community."
