Early Studies
The first systematic studies appeared in the late 1980s in publications by Tantam (1988) in the UK, Gillberg and Gilbert in Sweden (1989), and Szatmari, Bartolucci and Bremmer (1989) in North America. The diagnostic criteria for AS were outlined by Gillberg and Gillberg in 1989; Szatmari also proposed criteria in 1989. Asperger's work became more widely available in English when Uta Frith, an early researcher of Kannerian autism, translated his original paper in 1991. AS became a distinct diagnosis in 1992, when it was included in the 10th published edition of the World Health Organization’s diagnostic manual, International Classification of Diseases (ICD-10); in 1994, it was added to the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) as Asperger's Disorder.

Famous quotes containing the words early and/or studies:
“The Americans never use the word peasant, because they have no idea of the class which that term denotes; the ignorance of more remote ages, the simplicity of rural life, and the rusticity of the villager have not been preserved among them; and they are alike unacquainted with the virtues, the vices, the coarse habits, and the simple graces of an early stage of civilization.”
—Alexis de Tocqueville (1805–1859)
“[B]y going to the College [William and Mary] I shall get a more universal Acquaintance, which may hereafter be serviceable to me; and I suppose I can pursue my Studies in the Greek and Latin as well there as here, and likewise learn something of the Mathematics.”
—Thomas Jefferson (1743–1826)
