What Causes the Increase in Autism Rates?
Prevalence rates of autism spectrum disorder (ASD) have risen sharply in recent decades, capturing the attention of parents, educators, and healthcare professionals.
While these numbers indicate greater awareness and diagnostic capabilities for autism, they also spark questions about the potential for overdiagnosis.
Many people wonder: What causes the increase in autism rates? They also ask how families and professionals can ensure early intervention while being careful not to overdiagnose.
The answer lies in understanding the complexities of autism prevalence, including factors like external pressures, diagnostic criteria changes, and our evolving knowledge of the condition.
Next, we must examine factors that may contribute to overdiagnosis.
In this blog by ABA Centers of New Jersey, we’ll unpack the topic of autism prevalence. We will also explore contributing factors, misconceptions, and the implications of overdiagnosis.
Finally, we will provide a brief overview of how ABA therapy can help.
So, please keep reading to learn more about this critical yet often misunderstood topic!

Understanding Overdiagnosis and Autism Spectrum Disorder
According to the National Institute of Health, overdiagnosis refers to the identification of a condition that does not provide any benefits from early treatment to the individual.
In simpler terms, without a diagnosis, there would be no symptoms or fatalities associated with the condition.
In autism, “overdiagnosis” means that people are diagnosed with ASD more often than they should be. This overdiagnosis occurs for different reasons and leads to more ASD diagnoses for individuals who do not show symptoms or feel any distress related to the condition.
For many practitioners, the challenge lies in distinguishing between appropriate diagnoses and true overdiagnoses.
How Overdiagnosis Occurs in the Context of Autism Spectrum Disorder
The following are some common factors that can increase the likelihood of overdiagnosis in autism:
1. Diagnostic Bias
The subjective nature of the diagnostic process for autism can unintentionally lead various professionals to interpret symptoms differently. As a result, some patients may receive an autism diagnosis when they do not meet the full criteria.
2. Comorbid Conditions and Coexisting Symptoms
Some individuals may present to medical practitioners with overlapping symptoms of conditions. In these cases, comorbid conditions can sometimes complicate accurate diagnosis for practitioners and unintentionally increase the risk of an inaccurate diagnosis.
3. External Pressures
Parents may feel pressure to seek a diagnosis of autism for their child due to increases in developmental awareness and the benefit early intervention services can provide.
Similarly, healthcare professionals may feel pressure to give a diagnosis to access these services for their patients.
4. Misinterpretation of Developmental Milestones
There is a wide range of normal development variations in children. Sometimes, this can lead parents or professionals to interpret certain behaviors as indicative of autism when they are not.
All these factors, among others, can contribute to overdiagnosis and misconceptions about rising autism rates. However, it’s essential to recognize that overdiagnosis does not necessarily mean a lack of genuine cases of ASD.
4 Factors Contributing to Rising Autism Prevalence Rates
The most recent CDC estimates that approximately 1 in 36 children in the United States has been diagnosed with ASD. This statistic is significantly higher in comparison to 2002, when the prevalence rate was roughly 1 in 150 children.
Here are four factors that can influence autism prevalence rates:
1. Increases in Awareness and Diagnostic Capabilities
Increases in societal awareness of ASD have led to more accurate identification and diagnosis of neurodivergent individuals. This awareness includes recognizing symptoms at a younger age to provide early intervention.
2. Changes in Diagnosis Criteria
The diagnostic criteria for ASD have undergone revisions and updates. These changes have broadened the definition of autism, leading more individuals to meet the criteria for an autism diagnosis than before.
3. Increased Acceptance and Decreased Stigma
The societal stigma surrounding autism has decreased in recent years. As a result, more families seek a diagnosis for their child. As a result, healthcare professionals report increases in cases and tests.
4. Testing in Rural Communities
Rural areas may have previously had lower rates of testing and diagnosis compared to urban environments.
However, with increased access to healthcare resources in these communities, the prevalence rates of autism may now demonstrate a more accurate representation of the demographic.
4 Major Implications of Overdiagnosis
The potential for overdiagnosis in autism comes with significant implications. These include but may not be limited to:
1. Sticky Labels and Unnecessary Stigma
A misdiagnosis of autism can lead to unnecessary labeling and stigma for the individual. This stigma can impact their self-esteem, social interactions, and overall well-being.
2. Inappropriate Treatment Plans
An incorrect diagnosis can result in treatment plans that do not meet the individual’s specific needs. As a result, individuals may miss the chance to address coexisting conditions and symptoms with more appropriate programming.
Inappropriate treatment plans can also cause individuals to miss opportunities to develop organically without treatment in some cases.
3. Financial Burden
Seeking a diagnosis and managing treatment for ASD can be costly for families. A misdiagnosis can add financial burden without providing the proper support and resources. It can also lead to unnecessary medical expenses and interventions.
4. Ethical Concerns in Overdiagnosis
When individuals receive an inaccurate diagnosis, they may unintentionally divert resources from those who genuinely require them to those who may not.
ABA Therapy and Overdiagnosis in Autism
ABA therapy is an evidence-based intervention that’s effective in supporting many individuals with ASD to develop skill sets that serve them across their lives. ABA can also help families address stigma and other challenges that arise with raising a neurodivergent child.
In most cases, ABA accomplishes this through positive reinforcement strategies.
ABA professionals can also sometimes help identify coexisting conditions in their clients or note that a child receiving programming may not have autism so that they can retest.
Finding the Right Balance Is Possible in Avoiding Autism Overdiagnosis
The rise in autism prevalence rates has brought both progress and new challenges that society needs to address. On the one hand, increased awareness and acceptance of ASD helps individuals find the support they need. On the other hand, concerns about overdiagnosis have grown and may present barriers to change.
Ultimately, even with risk factors like overdiagnosis to consider, society should continue to learn more about autism prevalence rates and encourage ethical testing measures.
Avoiding overdiagnosis doesn’t mean limiting access to services. It means improving how we identify, understand, and use the diagnostic tools available to us to treat and diagnose autism with the most precision possible.
So, keep learning and remember that each person with autism is unique and deserving of the proper support.
