Have you been denied assistance because your autism diagnosis was missed in childhood? If so, you're not alone. In this post, Dr. Regan provides you with new information from the Center for Disease Control (CDC) that will empower you to advocate for your needs.



MOST ADULTS WITH AUTISM ARE UNDIAGNOSED OR MISDIAGNOSED


The belief that autism is a diagnosis reliably made in childhood is one of the most unyielding myths about the spectrum. Although gains in the understanding and detection of autism have evolved over the last few decades, we are far from having a perfect diagnostic system. Many children fall through the cracks and are left undiagnosed or misdiagnosed as adults.


One of the most devastating impacts of this myth has been the formation of public and legal policies stating that, if pediatric records have not documented the condition, a diagnosis in adulthood is not recognized as vaid. Consequently, the individual is ineligible for autism support services in the community.


The conceptualization of autism as a pediatric condition is also perpetuated a significant lack of research in adult populations. The scientific void has created the perfect environment for inappropriate policies to remain in place without challenge.


EMERGING DATA TO SHIFT POLICY


The near absence of research on autism in adulthood includes measurement of its prevalence across the lifespan. Croen et al. (2015) provided a peek at existing diagnostic rates in adults. The researchers searched the Kaiser Permanente medical database for existing diagnoses in the records of over 3-million patients. Only 0.1% of the patients had an existing diagnosis of autism in the medical record.


Although a large-scale study in the United Kingdom (Brugha, 2011) documented that many adults are missing a correct diagnosis on the spectrum, no regional studies have addressed this topic in the United States.


NEW CDC STATEMENT


The new CDC publication documents an estimated autism prevalence rate of 2.2% within the United States. This number stands in stark contrast to Croen's finding of 0.1% of adults with an established diagnoses.


The recent CDC publication further states, "ASD is a lifelong condition, and many adults with ASD need ongoing services and supports. The findings from this study can help states determine the need for diagnosing and providing services to adults in the United States who remain unidentified with ASD."



The CDC's recent statement may be the first step in a journey to legitimize an adult diagnosis within science, policy, and law.
