The term pervasive developmental disorders (PDDs) refers to a group of developmental conditions that involve delayed or impaired communication and social skills, behaviors, and cognitive skills (learning).
Because autism is the best-known of the PDDs, the disorders also are known as autism spectrum disorders (ASDs).
PDDs include Asperger syndrome and two less common conditions, childhood disintegrative disorder and Rett syndrome. PDDs usually are diagnosed during infancy, toddlerhood, or early childhood.
Causes of autism are not yet well understood. Scientists believe they’re complex neurobiological (brain biology) problems, which might have a genetic basis like other conditions that stem from abnormalities in the chromosomes a child inherits.
Some studies have suggested that autism might stem from a host of causes, including food allergies, excessive amounts of yeast in the digestive tract, and exposure to environmental toxins. However, these theories aren’t scientifically proven.
The vast majority of scientific studies have found no link between vaccines — or any of their ingredients—and autism. The 1998 study that suggested such a link has since been retracted by the medical journal that originally published the flawed research. It’s also important to remember that autism is not caused by parenting or bad experiences. Earlier notions that suggested this have been debunked.
Although there’s no cure for autism, early intervention and treatment can help kids develop skills and achieve their best potential. No medications can cure PDDs, but sometimes they’re used to treat certain symptoms, such as aggression toward self or others, problems of inattention, obsessive-compulsive behaviors, and mood swings.
Individually tailored programs can include behavior modification, and educational interventions can help shape a child’s behaviors and improve speech and communication. Therapy should be individualized because each child’s disorder is distinct and presents specific needs, and ASDs can range from mild to severe. Some kids do well in small classes with lots of one-on-one attention. Others do well in standard classrooms with support.
The goal of treatment is to get kids with PDDs to a point where they can be mainstreamed into a regular classroom, although they also might require special programs and support services, including speech-language therapy. Gluten-free and casein-free diets have been reported to show some positive results in helping some children with autism, although more research needs to be done. Other vitamin and herbal remedies have not been scientifically proven, although they may have value for some kids.
Families who are considering using these or other treatments will want to discuss any possible benefits or risks with their doctor before beginning.
HELPING YOUR CHILD
Once you learn your child may have autism, it’s important to get help. Even before a formal diagnosis is made, your child can begin early intervention to address language and other delays.
Kids with disabilities are entitled to free preschool services at three years of age under the Individuals with Disabilities Education Act (IDEA). Check out the services offered by your local school district, Intermediate Unit, or organizations such as Easter Seals and United Cerebral Palsy (UCP). Also under the IDEA, states provide services for children with disabilities from birth through age two through federally mandated early intervention programs.
Because the needs of kids with autism spectrum disorders vary, any education program must be tailored to the individual child. You can set up an individualized education plan (IEP) for your child though your local school district. An IEP should incorporate social skills and communication and be very structured. Maximized speech and language intervention is important, as is the use of behavior modification and rewards to try to stop problem behaviors and to encourage all types of communication. For kids younger than 3 years old, parents will work with the state’s early intervention program to develop an Individualized Family Service Plan (IFSP) instead of an IEP. As with all developmental concerns, talk with your doctor about how to find local resources for the services your child needs.
If your child is in school, talk with his or her teachers to find out what rewards and behavior modification techniques help in the classroom and try using some of these at home. That way, your child will get a consistent message at home and at school.#
