As an expert in the field of developmental disorders, it's important to note that the prevalence of autism spectrum disorders (ASD) is a topic of ongoing research and discussion. The data provided in the statement from the Centers for Disease Control and Prevention (CDC) indicates a significant increase in the prevalence of ASD among children in the United States. However, to provide a comprehensive answer, we must consider several factors, including the definition of autism, the methods of diagnosis, and the potential reasons for the observed increase.
Autism Spectrum Disorder (ASD): Autism is a complex neurodevelopmental disorder that affects how a person communicates, interacts with others, and experiences the world around them. It is characterized by difficulties in social interaction, communication, and repetitive or restrictive behaviors. The term "spectrum" in ASD refers to the wide range of symptoms and levels of impairment that can vary from person to person.
Diagnosis: The diagnosis of ASD has evolved over time. It now includes conditions that were previously considered separate, such as Asperger's syndrome and pervasive developmental disorder not otherwise specified (PDD-NOS). This broader diagnostic criteria has likely contributed to the increase in the number of children identified with ASD.
Prevalence: The CDC's report from March 28, 2014, states that one in 68 U.S. children has an ASD, which represents a 30% increase from the previous estimate of one in 88 children. This increase could be due to a variety of factors, including:
1. Improved Awareness and Diagnosis: There has been a significant increase in public awareness about autism, leading to earlier and more frequent diagnoses.
2. Broader Diagnostic Criteria: As mentioned earlier, the expansion of the diagnostic criteria to include a broader range of behaviors and symptoms has led to more individuals being diagnosed with ASD.
3. Changes in Reporting: There may be changes in how data is collected and reported, which could affect the prevalence rates.
4. Environmental and Genetic Factors: While the exact causes of autism are still under investigation, research suggests that a combination of genetic and environmental factors may play a role.
Global Perspective: The prevalence of ASD varies by country and region, and it is influenced by cultural, diagnostic, and reporting practices. While the CDC's figures are specific to the United States, it is important to recognize that these rates may not be directly comparable to those in other parts of the world.
Challenges in Estimation: Estimating the number of children with autism is challenging due to the nature of the disorder, the variability in symptoms, and the methods used for diagnosis and tracking. Additionally, there is a need for ongoing research to better understand the causes of autism and to develop more effective interventions.
Implications: The increase in the prevalence of ASD has significant implications for families, educational systems, healthcare providers, and society as a whole. It highlights the need for increased support and resources to ensure that individuals with ASD can lead fulfilling and productive lives.
In conclusion, while the CDC's report provides a snapshot of the prevalence of ASD in the U.S., it is crucial to consider the broader context and the factors that may contribute to these numbers. The understanding of autism is continually evolving, and it is essential to stay informed about the latest research and developments in the field.

A new government survey of parents suggests that 1 in 45 children, ages 3 through 17, have been diagnosed with autism spectrum disorder (ASD). This is notably higher than the official government estimate of 1 in 68 American children with autism, by the Centers for Disease Control and Prevention (CDC).Nov 13, 2015
