Not long ago, autism was assumed to be comparatively rare, affecting as few as 1 in 10,000 people. The latest studies, however, suggest that as many as 1 in 150 kids age 10 and younger may be affected by autismJ. Madeleine Nash
But what researchers have come to agree on is that autism is a "spectrum" disorder. In other words, it's not a condition with a single set of symptoms. Instead, affected children face different challenges—and there are different levels of severity.Melissa Fay Greene

Word History

Etymology

borrowed from German Autismus "group of supposed symptoms of schizophrenia that involve a turning away from reality," from Greek autós "self, the same" + German -ismus -ism — more at auto-

Note: The German term Autismus was introduced, along with the corresponding adjective autistisch (see autistic), by the Swiss psychiatrist Eugen Bleuler (1857-1939), in the paper "Zur Theorie des schizophrenen Negativismus," Psychiatrisch-Neurologische Wochenschrift, Nr. 19 (August 6, 1910), 12. Jahrgang 1910/11, pp. 184-98. Adaptation of the word in English to designate what is now termed autism spectrum disorder has been credited to the Austrian-born American physician and psychiatrist Leo Kanner (1894-1981), in the paper "Autistic Disturbances of Affective Contact," The Nervous Child, vol. 2 (1943), pp. 217-50. German Autismus and autistisch were used five years earlier to describe essentially the same syndrome by the Austrian physician Hans Asperger (1906-80), in an article in Wiener klinische Wochenschrift ("Das psychisch abnorme Kind," Band 51 [1938], pp. 1314-17), the text of a lecture given on October 3, 1938: "Innerhalb dieser wohl charakterisierten Gruppe von Kindern, die wir wegen der Einengung ihrer Beziehungen zur Umwelt, wegen der Beschränkung auf das eigene Selbst (αυτός) 'autistische Psychopathen' nennen, gibt es nun freilich wieder recht verschiedene, auch recht verschieden zu bewertende Menschen." ("Within this well-characterized group of children, whom we call 'autistic psychopaths' owing to the narrowing of connections to their surroundings and restriction to their own selves (autós), there are to be sure quite a variety of people, among them people to be variably evaluated.") (Note that psychopath here means simply "person judged to be suffering from some mental disorder"—it does not have its current English meaning.) Asperger later acknowledged that the terms Autismus and autistisch had originally been used by Bleuler.
