The History of the Autism Diagnosis

If you are parenting a child who has recently been diagnosed with Autism Spectrum Disorder, or you are wondering whether an evaluation might be helpful, you may have found yourself asking: How did autism become what it is today? Why do adults describe such different diagnostic experiences? Why does it seem like so many more children are being diagnosed now?

These are thoughtful questions. Understanding the history of autism can make today’s diagnostic process feel less overwhelming and often more validating.

The truth is, autism has not suddenly appeared in recent decades. What has changed is our understanding.

1925: The woman who saw autism first

Most people learn that autism was first identified in the 1940s by Leo Kanner or Hans Asperger. But history tells a more complete story.

In 1925, nearly twenty years earlier, Soviet child psychiatrist Grunya Sukhareva published detailed descriptions of six children whose traits closely match what we now recognize as autism.

She observed deep interests, social differences, sensory sensitivities, literal and analytical thinking, motor coordination differences, preference for routine, and remarkable intelligence and originality.

What is especially striking is how modern her observations feel. Rather than focusing only on deficits, Dr. Sukhareva also noticed strengths: honesty, exceptional memory, creativity, intense concentration, and unique ways of thinking.

So why don’t more people know her name? She published in Russian and German, worked in the Soviet Union during a politically isolated era, and like many women in early medicine, her contributions were largely overlooked. Today, many historians recognize Dr. Sukhareva as the first clinician to accurately describe autism.

Before autism had a name

Before the 1920s, and for many years afterward, children who would likely be identified as autistic today were often misunderstood.

They might have been described as shy, in their own world, intellectually disabled, emotionally disturbed, behaviorally difficult, or unusually gifted but socially disconnected.

Families often had no language for what they were seeing. Without understanding, many parents carried unnecessary guilt, confusion, or blame.

The 1940s: Autism enters mainstream psychiatry

In 1943, Leo Kanner published a paper describing 11 children with what he called early infantile autism. He noted differences in social connection, strong need for sameness, repetitive behaviors, communication differences, and intense focus on specific interests.

Just one year later, in 1944, Hans Asperger described children who had strong language and intellectual abilities but struggled socially and showed highly focused interests.

For many years, these men were credited as the pioneers of autism research, though we now know Dr. Sukhareva came first.

The harmful refrigerator mother era

In the 1950s and 1960s, one of the most painful chapters in autism history emerged. Some professionals wrongly believed autism was caused by emotionally distant mothers, a theory often associated with psychologist Bruno Bettelheim.

Parents, especially mothers, were blamed for their children’s differences. We now know this was completely false. Autism is a neurodevelopmental difference, not the result of parenting style, attachment, or emotional warmth.

1980: Autism becomes an official diagnosis

A major turning point came in 1980 when the American Psychiatric Association included autism in the Diagnostic and Statistical Manual, Third Edition.

For the first time, autism became an official diagnostic category. This helped standardize evaluations, support research, improve access to services, and reduce blame on families.

However, the criteria were still narrow. Many children, especially girls, verbal children, and children with average or above-average intelligence, were still being missed.

The 1990s and 2000s: A broader understanding emerges

As research expanded, clinicians realized autism could look very different from person to person.

Some children spoke early, made eye contact, excelled academically, masked their social struggles, or appeared fine in structured environments while working incredibly hard internally.

During this period, diagnoses included Autistic Disorder, Asperger’s Disorder, and PDD-NOS. While helpful at the time, these labels often created confusion.

2013: Autism Spectrum Disorder

In 2013, the American Psychiatric Association introduced the DSM-5. Previous autism-related diagnoses were brought together under one umbrella: Autism Spectrum Disorder.

This reflected an important truth. Autism is not separate boxes. It is a spectrum.

Some children need significant support. Others speak fluently, excel academically, and still work incredibly hard to navigate a world not designed for their nervous systems. Both experiences are autism.

Why are more children being diagnosed today?

This is one of the most common questions parents ask. The rise in diagnoses does not mean autism is suddenly more common. It means we are getting better at recognizing it.

• Better awareness among parents, teachers, pediatricians, and therapists.
• Broader diagnostic criteria that recognize autism can present differently across individuals.
• Improved identification of girls and children from historically overlooked communities.
• Earlier developmental screening, often during pediatric visits at 18 and 24 months.

What this means for parents today

If your child has recently been diagnosed, or you are considering an evaluation, you are living in a very different era than families did 30, 50, or 100 years ago.

Today, diagnosis can be a roadmap, an explanation, access to support, and a deeper understanding of your child.

Perhaps the most important lesson from history, starting with Dr. Grunya Sukhareva nearly a century ago, is this: autism has always been a different way of experiencing the world.

Your child is still the same child they were before the diagnosis, now with more language, more understanding, and hopefully, more support.
