Getting diagnosed with autism later in life, whether it’s in your 20s or 40s or even your 60s, can be a total game-changer. It can impact your entire sense of identity and how you interact with the world and others. It can also bring a profound feeling of relief while answering many questions, including: why did it take so long to figure this out?
Today, the Centers for Disease Control and Prevention (CDC) estimates that one in 45 adults is autistic, and even more are likely undiagnosed. This rise is due to the improved understanding of the condition (and acknowledgement that autism is a true spectrum, rather than a collection of specific traits) thus leading to updated diagnostic criteria.
When autism is diagnosed in adulthood, it doesn’t mean that someone only developed the signs of autism later in life. In most cases, they had been living with undiagnosed autism since childhood, and belong to what experts call the “lost generation.” “These adults missed out on services, and therefore often experience pretty significant challenges, including mental health conditions,” says Jackie Shinall, PsyD, head of reliability and quality assurance at Prosper Health.
There are many reasons for lost generation autism. In addition to a previous lack of awareness of autism in adults, outdated diagnostic criteria allowed even more people to slip through the cracks.
In the past, autism was primarily viewed through the lens of the “classic” presentation (the stereotypical autistic male you’re picturing), so more subtle signs were often missed. “In some cases, this relates to the broadening of the autism spectrum, as there are some individuals who would not have met the diagnostic criteria in the past, but now do meet the criteria as it has evolved and our understanding of autism continues to improve,” says Heather Flynn, PhD, a licensed clinical psychologist specializing in autism assessments for individuals of all ages.
