    How Common Is Autism Spectrum Disorders?

    Autism and related disorders affect an estimated 1 in 68 children. According to the CDC, more children today are diagnosed with ASD than ever before. Experts aren't sure if autism is getting more common or if doctors are just better at diagnosing the disorders.

    How Is ASD Diagnosed?

    If autism spectrum disorders symptoms are present, the doctor will begin an evaluation by performing a complete medical history and physical and neurological exam. Although there are no laboratory tests for autism, the doctor may use various tests -- such as X-rays and blood tests -- to determine if there is a physical, genetic, or metabolic disorder causing the symptoms.

    If no physical disorder is found, the child may be referred to a specialist in childhood development disorders, such as a child and adolescent psychiatrist or psychologist, pediatric neurologist, developmental-behavioral pediatrician, or another health professional who is specially trained to diagnose and treat autism. The doctor bases his or her diagnosis on the child's level of development, and the doctor's observation of the child's speech and behavior, including his or her play and ability to socialize with others. The doctor often seeks input from the child's parents, teachers, and other adults who are familiar with the child's symptoms.

    How Is Autism Treated?

    There currently is no cure for autism, but treatment may allow for relatively normal development in the child and reduce undesirable behaviors. Children with autism generally benefit most from a highly structured environment and routines. Treatment for autism may include a combination of the following:

    • Special education: Education is structured to meet the child's unique educational needs.
    • Behavior modification: This includes strategies for supporting positive behavior and decreasing problem behaviors.
    • Speech, physical, or occupational therapy: These therapies are designed to increase the child's functional abilities.
    • Social skills therapies : These therapies address language and social pragmatics in those verbal individuals with autism.
    • Medication: There are no medications currently approved to treat autism, but medications may be used to treat certain symptoms, such as anxiety, hyperactivity, sleep disturbance, and other behaviors that may lead to injury.
