When was autism discovered

Imagine a time, not too long ago, when the word "autism" wasn't something many people knew. Just like discovering a new star in the sky, understanding autism has been a journey. It wasn't like someone suddenly shouted, "Aha! I've found it!" Instead, it was more like carefully putting together pieces of a puzzle over many, many years. You might hear names like Leo Kanner and Hans Asperger when people talk about discovering autism, and they did do some super important work 1. But even before them, people noticed that some kids were a little different in how they played, talked, and made friends. Think of it like this: before we had a name for the color orange, people still saw things that were orange.

They just didn't have that specific word for it yet. It's kind of the same with autism. People noticed the "orange" behaviors, but they didn't have the word "autism" to describe them 3. So, when was autism discovered? Well, it's not a simple date on a calendar. It's a story that unfolds over time, with many people adding their own important parts to it. Let's take a trip back in time and see how we started to understand this special way of being.

Before "Autism": Recognizing Unique Traits

Even before doctors had the word "autism," there were stories and writings about people who had some of the traits we now know are part of autism. It's like finding footprints before you know what animal made them. Way back in 1747, there's a story about a man named Hugh Blair of Borgue. People noticed he was different in a way that affected his marriage 4. While they didn't say "autism," looking back, some experts think he might have had traits we recognize today. Then, around the time of the American Revolution, there was a really smart scientist named Henry Cavendish (first published in 1766). People thought he was very shy and acted strangely 4. A doctor who studies the brain even looked at his life story and thought, "Wow, this sounds a lot like autism!" Imagine a boy who grew up in the woods all by himself in 1798. They called him the Wild Boy of Aveyron. He didn't talk, and he acted very differently 3. Today, some experts think he might have been autistic and was left alone because of it. Around 1810, a doctor in France named Jean-Étienne Dominique Esquirol talked about people who were really focused on just one idea 4. This could be a little like the intense interests some autistic people have. Later, in 1877, another doctor in Germany, Adolf Kussmaul, wrote about people who chose not to speak 4. Maybe some of these folks were autistic and non-verbal. In 1887, a doctor named John Down described "idiots savants." These were people who weren't good at many things but were super talented in one specific area, like remembering lots of numbers or playing music really well 4. This is something we sometimes see in autistic people too.

Think about a boy from a long time ago, in the middle of the 1800s, named Billy. People thought he had trouble understanding things, but he could hear music perfectly and knew over 200 songs! Even though they called him an "idiot" back then, we can see he had some amazing abilities 3. There was also a girl named Laura Bridgman in the 1800s who couldn't see or hear. People were amazed by her, and even a famous writer, Charles Dickens, wrote about her kindness 3. This shows that even when people have big differences, they can still have wonderful qualities. Around the 1920s, a doctor in Russia named Grunya Sukhareva carefully watched some children. She wrote down how they acted, like how one boy taught himself to read super early but preferred being with grown-ups 4. She noticed they sometimes liked to be alone and do the same things over and over. Her descriptions from 1925 sound a lot like how we describe autism today! She even focused on the things these children were good at. Examples included a boy who taught himself to read at age five, preferred adults over peers, and was physically awkward. She also described a child who was a talented violinist but struggled with social cues, and another who was mathematically gifted but couldn't recognize faces 5. Sukhareva noted that these children found it hard to adapt, often preferred solitude and repetitive tasks, and had a certain flatness of emotions 4.

Long before the word "autism" was used, people noticed that some individuals had unique ways of interacting with the world, communicating, and having specific interests. These early observations, though not labeled as autism, show that these traits have been present throughout history 3. The variety of these historical examples, spanning different time periods and continents, suggests that characteristics now recognized as autistic have always been a part of the human population. The absence of a specific diagnostic framework meant these individuals were often misunderstood or categorized using broader terms like "idiot" or associated with conditions such as schizophrenia 3. The way people described these differences in the past often reflected the understanding and language of that time. Terms like "idiot" or associations with other conditions highlight the evolution of our knowledge 3. The labels used in these early accounts, such as "idiot" or "schizoid psychopathy," illustrate how societal understanding of neurodevelopmental differences has transformed over time. What was once viewed as a general intellectual disability or a precursor to schizophrenia is now recognized as a distinct condition with its own specific set of characteristics 3.

Coining the Term: Eugen Bleuler's Contribution

The actual word "autism" was first used by a doctor from Switzerland named Eugen Bleuler. This was in the early 1900s, around 1908 or 1911 1. But, and this is important, Bleuler was studying something called schizophrenia, which is different from autism. He used "autism" to describe how some people with schizophrenia seemed to pull away from the real world and live more in their own minds 5. He said it was like a "detachment from reality" and a focus on their "inner life" 5. The word "autism" comes from the Greek word "autós," which means "self" 1. So, Bleuler was using it to talk about this "self-centered" way of thinking in some of his patients. It's like if you saw someone playing alone and you said they were being "self-absorbed." That's kind of how Bleuler used the word, but for people with a specific mental health condition. It wasn't until later that "autism" started to mean the condition we know today 2.

The initial use of "autism" by Eugen Bleuler was within the context of schizophrenia, where it described a symptom of withdrawal and a focus on inner life 5. This is a key point because it highlights that the term's original meaning is distinct from the current understanding of autism spectrum disorder, which is recognized as a neurodevelopmental condition in its own right 2. Bleuler's work was foundational in the study of schizophrenia, and his introduction of the term "autism" within that framework demonstrates the evolving nature of scientific understanding and terminology 1. A single word can carry different meanings as research progresses and new discoveries are made. While Bleuler coined the term, it did not immediately lead to the recognition of autism as a separate condition 2. For several decades, the term remained primarily associated with schizophrenia 2. The shift towards recognizing autism as its own entity required further research and observations by other pioneering figures in the field 2. Bleuler's initial use of the term, though different from the modern understanding, did lay the groundwork for future researchers to use and redefine the word in relation to the specific set of traits we now associate with autism 1. His focus on an inward withdrawal and detachment may have influenced later researchers like Kanner and Asperger as they began to describe similar characteristics in children who did not necessarily have schizophrenia 3.

A Landmark Study: Kanner's 1943 Publication

A really important moment in understanding autism came in 1943 when a doctor named Leo Kanner wrote a big paper. He was an Austrian-American child psychiatrist working in a hospital called Johns Hopkins 2. His paper was called "Autistic Disturbances of Affective Contact," and it was published in a journal called Nervous Child 6. In this paper, Dr. Kanner described 11 children he had been watching. These children had some special ways of being that were different from other kids. He called what he saw "early infantile autism" or "Kanner syndrome" 2.

He noticed some important things about these children. They seemed very alone in their own world and had trouble making friends or connecting with people. He called this "extreme autistic aloneness" 9. Some of them didn't talk much, or they might repeat words they heard, which is called "delayed echolalia" 9. They really liked things to stay the same and might get upset if their routines changed, even in small ways. This was like an "anxiously obsessive desire for the maintenance of sameness" 13. They might be very interested in objects and do the same things with them over and over 13. Even though they had these differences, Dr. Kanner noticed that many of them were actually quite smart in other ways 3. Dr. Kanner said that this wasn't the same as schizophrenia or just being slow at learning 13. He thought it was a special way some children were born 14. He even thought it might be something rare 16.

Leo Kanner's 1943 paper represents a pivotal moment in the history of autism research. It provided the first comprehensive and systematic description of autism as a unique condition, distinct from other developmental and psychiatric disorders 13. This work is widely considered the foundation upon which our modern understanding of autism is built. By carefully observing and documenting the shared behavioral patterns among the eleven children in his study, Kanner established a clear clinical picture that differentiated autism from conditions like intellectual disability, deaf-mutism, aphasia, and brain damage, with which it had previously been confused 17. His meticulous approach and detailed case studies brought much-needed clarity to a previously poorly understood area of child development 14. The specific characteristics that Kanner identified in these children, including difficulties in social interaction, impairments in communication, repetitive behaviors, and a strong preference for sameness, became the cornerstone of diagnostic criteria for autism for many years 13. His emphasis on the early onset of these symptoms was also significant 13. Kanner's work sparked considerable interest within the medical and psychological communities and paved the way for future research into the causes, diagnosis, and interventions for autism 14.

It is important to acknowledge a later discredited theory that sometimes became associated with early interpretations of Kanner's work: the "refrigerator mother" theory 7. This harmful idea suggested that cold and unemotional parenting, particularly by mothers, was a primary cause of autism. However, this theory faced significant backlash and has been definitively disproven by subsequent research 13. It is crucial to understand that autism is now recognized as a neurodevelopmental condition with a strong genetic component and is not caused by parenting styles 14. Kanner himself, while initially focusing on the observable behaviors of both the children and their parents, later emphasized the innate nature of autism and did not fully endorse the "refrigerator mother" hypothesis as it was later popularized 28. His primary contribution remains the clear and distinct clinical description of early infantile autism, which laid the foundation for the field 13.

A Viennese Perspective: Asperger's "Autistic Psychopathy"

Around the same time as Dr. Kanner, another doctor named Hans Asperger was working in Vienna, Austria. He was also looking at children who seemed to have some similar ways of being 1. In 1944, Dr. Asperger wrote about the children he observed and called what he saw "autistic psychopathy" 5. There were some similarities between what Dr. Asperger saw and what Dr. Kanner described. Both noticed kids who had trouble with social interactions, struggled with understanding social cues, and had really strong interests in specific things 5.

But there was also a big difference. The children Dr. Asperger studied often had good language skills and seemed to be quite intelligent, unlike some of the children Dr. Kanner wrote about who had more trouble with talking 16. Dr. Asperger also noticed that these children might have trouble making friends, have conversations that were mostly about their own interests, and sometimes be a bit clumsy 5. He even called them "little professors" because they knew so much about their favorite topics 35. Even though Dr. Asperger did this important work, not many people knew about it for a long time because his paper was written in German during World War II. It wasn't really until the late 1980s that his work was translated into English and became more widely known 5. A researcher named Lorna Wing played a big role in bringing Dr. Asperger's ideas to more people in 1981. She even used the term "Asperger's syndrome" to describe the condition he had written about 35.

Hans Asperger's work provided a valuable expansion to the initial understanding of autism presented by Kanner 7. While both researchers described children with difficulties in social interaction and communication, as well as repetitive behaviors and intense interests, Asperger's observations included children with a wider range of intellectual and linguistic abilities 9. Notably, the children Asperger described generally had fluent speech and vocabulary, even if their use of language was sometimes unusual, such as talking at length about their specific interests 16. This contrasted with Kanner's initial group, some of whom had significant language delays or did not speak at all 16. Asperger also highlighted challenges in forming friendships, a tendency towards one-sided conversations, and motor clumsiness 5. His characterization of these children as "little professors" reflected their often profound knowledge and ability to discuss their special interests in great detail 35. This broader view of autism, encompassing individuals with higher cognitive functioning, was a significant contribution that eventually led to the concept of an autism spectrum 21.

The delayed recognition of Asperger's work underscores the importance of accessible scientific communication 5. Published in German during World War II, his findings remained largely unknown to the international scientific community for several decades 5. It was not until the late 1980s, with the translation of his paper into English, that his observations gained wider recognition 5. Lorna Wing's 1981 paper, which explicitly used the term "Asperger's syndrome" and highlighted the similarities between Asperger's and Kanner's clinical observations, was crucial in bringing his work to the forefront 35. This delay in recognition demonstrates how geopolitical events and language barriers can impact the dissemination and integration of scientific knowledge, potentially slowing the progress of understanding complex conditions like autism.

It is vital to address the deeply troubling aspects of Hans Asperger's history and his connection to Nazi ideology 21. Recent research has revealed his complicity with the Nazi regime, including his referral of children to a Nazi clinic where they were ultimately murdered 42. His writings during this period reflected the discriminatory practices of Nazi psychiatry, and his descriptions of some autistic children as less "worthwhile" are abhorrent 42. This dark history has led to the discontinuation of "Asperger's syndrome" as a separate diagnostic category in both the DSM-5 and the ICD-11, with the understanding that what was previously referred to as Asperger's syndrome is now considered part of the broader autism spectrum 21. While acknowledging his early contributions to the description of autism, it is crucial to confront the ethical implications of his actions and the historical context in which his work occurred 41.

From Distinct Categories to a Unified Spectrum

After the initial groundbreaking work of Kanner and Asperger, the understanding of autism continued to evolve significantly 9. Over the subsequent decades, there was a growing recognition that autism was not a single, uniform condition, but rather a spectrum of related neurodevelopmental differences 9. This understanding was reflected in the changes made to the Diagnostic and Statistical Manual of Mental Disorders (DSM), the standard classification system used by healthcare professionals 25.

The DSM-III, published in 1980, marked a significant step by including "Infantile Autism" as a diagnostic category distinct from childhood schizophrenia 2. This edition provided specific diagnostic criteria, including impairments in communication, unusual responses to the environment, and a lack of interest in people, with onset before 30 months of age 25. The DSM-III-R in 1987 further refined these criteria and introduced "Pervasive Developmental Disorder-Not Otherwise Specified" (PDD-NOS), which broadened the concept of autism to include individuals who did not fully meet the criteria for autistic disorder 25.

A major shift occurred with the publication of the DSM-IV in 1994, which was the first edition to officially categorize autism as a "spectrum disorder" 6. This edition included several subcategories under the umbrella of Pervasive Developmental Disorders (PDDs), such as Autistic Disorder, Asperger's Disorder, PDD-NOS, Childhood Disintegrative Disorder (CDD), and Rett syndrome 21. This reflected a growing understanding of the diverse ways in which autism could manifest.

The most recent version, the DSM-5, released in 2013, brought about further significant changes by consolidating all the previous subcategories into a single diagnostic category called "Autism Spectrum Disorder" (ASD) 6. Rett syndrome and CDD were removed as separate diagnoses. The DSM-5 emphasizes two core symptom domains: persistent deficits in social communication and social interaction, and restricted, repetitive patterns of behavior, interests, or activities 25. Sensory sensitivities were also added as a diagnostic criterion 25. Additionally, a new diagnostic category of Social Communication Disorder (SCD) was introduced for individuals who have significant difficulties with social communication but do not exhibit restricted or repetitive behaviors 25.

The evolution of the DSM criteria illustrates a fundamental shift in the understanding of autism, moving from a narrow definition to a more inclusive and nuanced view of a spectrum of conditions 25. This acknowledges the wide variability in the presentation of autism and the unique profile of strengths and challenges that each autistic individual may possess 49. Furthermore, there has been a notable increase in the reported prevalence of autism over the years 9. This rise is likely attributable to several factors, including the broadening of diagnostic criteria, improved screening tools and diagnostic practices, and increased public and professional awareness of autism 9.

Addressing the Myths and Queries About Autism's History

People often wonder about the timeline of autism's discovery, and some common ideas about it are not entirely accurate 7. For instance, it's a common question whether autism is a recent phenomenon. The truth is, while the formal recognition and naming of autism occurred in the 20th century, descriptions of individuals exhibiting autistic traits can be found much earlier in history 10. Regarding who officially "discovered" autism, while Eugen Bleuler first used the term, Leo Kanner and Hans Asperger are widely credited with providing the initial detailed clinical descriptions of what we now understand as autism in the 1940s 1. It's also important to know that our understanding of autism has indeed changed significantly over time, evolving from an initial association with schizophrenia to its recognition as a distinct neurodevelopmental spectrum disorder 5.

Several misconceptions about autism's history also exist. One harmful myth is that autism is caused by "refrigerator mothers"—emotionally distant parents. This theory has been thoroughly discredited by scientific research, which now points to biological and genetic factors as primary contributors to autism 7. Another prevalent myth is that vaccines cause autism. Extensive scientific studies have consistently found no link between vaccines and autism 10. It's also a misconception that only boys can be autistic. While autism is diagnosed more frequently in males, females can also be autistic, although their presentation might sometimes differ, leading to underdiagnosis 10. Finally, it's crucial to remember that not all autistic people are the same. Autism is a spectrum, and each individual on the spectrum has a unique set of strengths and challenges 29.

Many outdated and harmful misconceptions about autism persist, often originating from early, limited understandings of the condition 10. Addressing these myths is essential for promoting accurate information and reducing the stigma associated with autism. Understanding the historical context of these misconceptions can aid in effectively debunking them and fostering a more informed and accepting society. The evolution of our understanding of autism, driven by increased awareness and scientific research, has directly challenged and refuted many of these early, simpler explanations 9. Ongoing scientific inquiry continues to refine our knowledge of autism, leading to a more nuanced and accurate understanding of this complex neurodevelopmental condition.

Looking Back, Moving Forward

So, when was autism discovered? As we've seen, it wasn't just one day or one person. It's been a long journey of noticing differences, giving them a name, and learning more and more about this special way of being. From the early stories of people who seemed a little different, to Eugen Bleuler giving us the word "autism," to the important work of Leo Kanner and Hans Asperger, and finally to understanding autism as a wide spectrum, we've come a long way. But the journey isn't over! Scientists are still learning so much about autism. By understanding the history, we can appreciate how far we've come and how important it is to keep learning and supporting everyone on the autism spectrum.

Your Questions Answered
