Autism, also called classic autism or autistic disorder, developmental disorder affecting physical, social, and language skills, with an onset of signs and symptoms typically before age three. The term autism (from the Greek autos, meaning “self”) was coined in 1911 by Swiss psychiatrist Eugen Bleuler, who used it to describe withdrawal into one’s inner world, a phenomenon he observed in individuals with schizophrenia. The use of the word autism to describe the condition as it is known today originated in 1943, when Austrian-born American psychiatrist Leo Kanner distinguished the disorder from schizophrenia.
