The word autism originates from the Greek word autos, meaning “self.” Swiss psychiatrist Eugen Bleuler first introduced the term in 1911 to describe social withdrawal in schizophrenia. Decades later, in 1943, Leo Kanner redefined the term as early infantile autism, marking the start of its association with childhood developmental disorders. Over time, the meaning evolved to represent a diverse spectrum of neurodevelopmental differences, leading to today’s term Autism Spectrum Disorder (ASD).
