Historical approach to the discovery of autism

Autism, a complex disorder that affects brain development and social interaction, has intrigued scientists, doctors and parents for decades. The condition, officially known as Autism Spectrum Disorder (ASD), has been the subject of intense research since it was formally recognized in the 1940s.

In this session, we will explore the roots and evolution of the understanding of autism, from early observations to contemporary scientific advances.

The First Glimpses of Autism

Although the term "autism" became popular in the 20th century, the characteristics of the disorder have been observed throughout history. In the 18th century, French physician Jean-Marc Gaspard Itard worked with a boy named Victor, the "Wild Child of Aveyron," who exhibited behaviors similar to those of autism. However, it was in the 1940s that the term "autism" was first used by psychiatrist Leo Kanner.

Pioneering Contributions of Leo Kanner and Hans Asperger

In 1943, Leo Kanner published a seminal paper describing "early infantile autism," focusing on the lack of social interaction and communicative skills in children. At the same time, in Austria, Hans Asperger also described a group of children with similar traits, giving rise to Asperger syndrome. These early investigations laid the groundwork for the formal recognition of autism as a clinical entity.

Evolution of Diagnostic Criteria

Over the following decades, the diagnostic criteria for autism underwent a significant evolution. In 1980, autism was officially included in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-III), providing a unified diagnostic structure. Subsequently, the DSM-IV and DSM-5 refined and expanded the definition of ASD, recognizing its diversity and complexity.

Neuroscientific and Genetic Research

With technological advances, neuroscientific and genetic research revealed new insights into autism. Brain imaging studies identified structural and functional differences in the brains of people with autism.

In parallel, genetic research uncovered certain genetic variants associated with an increased risk of developing autism, highlighting the multifactorial nature of the condition.

The Role of Therapies and Early Intervention

As scientific understanding of autism deepened, therapeutic approaches and early intervention programs were developed. Behavioral therapy, particularly Applied Behavior Therapy (ABA), proved effective in improving social and communication skills in children with autism. Early intervention became a mainstay, taking advantage of children's brain plasticity to maximize their development.

Current Challenges and Future Research Directions

Despite significant advances, autism continues to present significant challenges. Lack of resources, variability in clinical presentation, and disparities in access to care are problems that persist in many parts of the world. Future research directions focus on better understanding the underlying mechanisms of autism, developing more personalized interventions, and improving the quality of life for individuals with ASD.
