To Start

Autism’s journey resembles a kaleidoscope—once an indistinct blur, now a vibrant and lucid spectrum, continuously evolving as new patterns of understanding emerge. Autism was once mistaken for schizophrenia, but it is now a celebrated spectrum.

This article covers autism history from 1952 to now, serving as a go-to for those seeking information in the U.S.

It started as schizophrenia but tests and consultations distinguished it as Autism Spectrum Disorder.

Understanding autism’s journey requires looking back at its historical roots.

 

 Historical Perspectives

In 1952, many conflated autism with childhood schizophrenia or cold parenting.

(Read my last article for an explanation of Schizophrenia.)

In 1980, autism was reclassified as pervasive developmental disorder, distinct from schizophrenia and different from today’s understanding.

As perceptions shifted, so did the frameworks for understanding autism.

As the understanding of autism evolved, researchers faced significant challenges in distinguishing it from other conditions like schizophrenia.

Evolution of Understanding

In the early years of autism research, distinguishing autism from other conditions like schizophrenia posed significant challenges.

Many children exhibiting autistic traits were often misdiagnosed with schizophrenia due to shared symptoms such as social withdrawal and communication difficulties.

These misconceptions were further fueled by societal beliefs that attributed such behaviors to cold parenting or emotional disturbances.

The DSM’s Role: Defining Autism Over the Decades

Recognizing the need for clearer diagnostic criteria, authorities implemented the DSM (Diagnostic and Statistical Manual of Mental Disorders) to elucidate autism diagnosis but left much open to interpretation.

Although the initial editions left much open to interpretation, they marked a crucial step toward understanding autism as a distinct condition.

The DSM’s evolving definitions played a pivotal role in shaping diagnosis, gradually moving away from the conflated views of autism and schizophrenia.

It was published in 1952 with limited focus on autism.

Researchers recognized autism as a mental disorder affecting development, not just a product of their early environment.

Recognizing these challenges, the introduction of the DSM marked a critical step forward.

DSM-II

Published in 1968, the DSM-II marked a pivotal moment as the second edition of the Diagnostic and Statistical Manual of Mental Disorders.”

It played a crucial role in establishing standardized criteria for psychiatric diagnoses, offering clinicians a unified framework for evaluation.

This edition notably began to distinguish autism from schizophrenia, setting the stage for a more nuanced understanding of developmental disorders. “I am different, not less.”

DSM-III

Then, the DSM-III came out and listed some criteria.

DSM-III Diagnostic Criteria for Autism:

  • Lack of Interest in People: Individuals may show little to no interest in interacting with others.
  • Severe Impairments in Communication: Challenges in verbal and non-verbal communication are prevalent.
  • Bizarre Reactions to the Environment: Unusual responses to environmental stimuli or changes.
  • Early Onset of Symptoms: Symptoms typically develop within the first 30 months of life

With evolving definitions, the DSM-III played a crucial role in shaping diagnosis.

Later, DSM-III revised the diagnosis, acknowledging that not all cases were extreme, so they added a new condition to their list which they were calling pervasive developmental disorder-not otherwise specified. This lengthy term described milder cases.

Building on these advancements, the DSM-IV further refined the classification of autism, inching towards a broader spectrum.

DSM-IV

Although it didn’t say spectrum, it began inching towards that definition. So instead of schizophrenia, it started being understood as a spectrum of disorders that all were labeled the same thing.

As expert Jordan Hilkowitz said, “Autism is not a tragedy. Running out of bacon is a tragedy.”

Between 1994 and 2000, experts labeled autism as a spectrum disorder through the DSM-IV, identifying it as five separate disorders:

 

DSM-IV Classification (1994-2000):

  • Autism
  • Pervasive Developmental Disorder-not Otherwise Specified (PDD-NOS)
  • Asperger’s Syndrome
  • Childhood Disintegrative Disorder (CDD): More commonly found in girls than boys.
  • Rett’s Syndrome

In 2003 they found over 100 genes that could play into autism, but none that were directly linked to it, so they decided to say that is more of a spectrum than a straight diagnosis.

“Our goal is to create a world where everyone belongs.”

DSM-V

The DSM-V was soon released also known as the DSM-5, and only then was the idea adopted of a continuous spectrum.

Before its release, many feared a spectrum diagnosis might disrupt their identity and belonging.

They feared it would reduce their pay and services. However, researchers found it helped more people get diagnosed.

As expert Gilles Trehin illustrates, “Autism is not a problem to be solved, but a reality to be experienced with joy.”

These pivotal changes in diagnostic criteria were driven by pioneering figures who reshaped our understanding of autism.

 Notable Figures in Autism History

Grunya Sukhareva

  • In 1925, Grunya Sukhareva pioneered the first clinical descriptions of autistic traits.
  • In the early 1920s, at a children’s psychiatric hospital in Moscow, Grunya Sukhareva observed boys whose behaviors markedly diverged from their peers.

  • These children were characterized by profound social withdrawal and an adherence to repetitive routines, yet they possessed remarkably intense interests in specific subjects.
  • Sukhareva meticulously chronicled these traits, capturing the subtleties and nuances with precision.
  • Her pioneering insights offered one of the earliest clinical depictions of what would later be recognized as autism traits.
  • This revolutionary work not only redefined contemporary understanding but also laid a crucial foundation for future explorations in the field.
  • Her revolutionary work provided early insights into behaviors that defined the autism spectrum, predating Kanner and Asperger.
  • While Grunya Sukhareva laid the groundwork for early autism research, Hans Asperger’s insights further expanded the understanding of the condition.

Hans Asperger

  • Hans Asperger once observed that “Not everything that steps out of line, and thus ‘abnormal,’ must necessarily be ‘inferior.’”
  • This perspective was pioneering, as he saw beyond challenges to the talents within, leading to the recognition of Asperger’s Syndrome.
  • While working at the University of Vienna, Hans Asperger observed a young boy who struggled socially but excelled in languages and math.
  • Noticing the boy’s potential, Asperger believed these “autistic psychopathy” traits were not deficits but unique strengths.
  • An Austrian pediatrician in the 1940s, Asperger’s work laid the foundation for understanding a unique presentation of autism.
  • His pioneering insights challenged conventional views and continue to shape how educators and clinicians perceive autism today.

Leo Kanner

  • Leo Kanner, often called the ‘father of child psychiatry,’ made a groundbreaking discovery in 1943.
  • In 1943 at Johns Hopkins Hospital, Leo Kanner studied 11 children exhibiting traits such as social withdrawal and a desire for sameness.
  • As a psychiatrist at Johns Hopkins Hospital, Kanner was the first to formally describe autism as a distinct condition.
  • Kanner’s detailed case studies were revolutionary, identifying autism as a distinct condition separate from schizophrenia. His work laid the foundation for modern autism research and diagnostics, shaping the field for decades to come.

Dr. Catherine Lord

  • She is the leading specialist in autism research today.
  • Her research focus is developing methods to identify strengths and difficulties in individuals with ASD.
  • Quote from the Semel Institute: “Her research and clinical work are aimed at improving methods of identifying strengths and difficulties…and working with families and individuals to maximize independence and well-being.”
