A Brief History of the Science of Autism Spectrum Disorder
Briefly

The article outlines the evolving history of autism, detailing its initial categorization by Leo Kanner in 1943 and Hans Asperger's work in 1944. Initially viewed as separate disorders, the merging of diagnostic categories, including Asperger's syndrome, has contributed to the rising prevalence of autism diagnoses. This increase is further influenced by genetic drift and increased awareness within society. Despite political and media tendencies to favor simple explanations for autism, the research indicates a complex interplay of factors that continue to evolve in understanding the spectrum of autism.
Increased prevalence of autism has been attributed to the merging of diagnostic categories, genetic factors, and heightened awareness rather than simply a rise in cases.
Kanner's initial studies highlighted differences in functioning levels, indicating a more complex understanding of autism beyond just the deficits in behavior and communication.
