“…For one thing, proposed changes to the Diagnostic and Statistical Manual of Mental Disorder (DSM) would remove communication from the three domains, and would also collapse the distinction between autism and cognate diagnoses like Asperger's Syndrome (APA, 2011). The one in one-hundred figure may have to be revised too -a March 2012 report from the Centres for Disease Control, in the United States, increased this to one in eighty-eight (CDC, 2012), while the £34-billion cost, already a notable increase from a 2009 estimate (Knapp et al, 2009), is described as 'tentative' (Knapp, 2012). More to the point, perhaps, there is also now some disagreement about whether the triad, causally, actually composes a single neurodevelopmental disorder (Geschwind and Levitt, 2007;Happé and Ronald, 2008), while the 'specific genetic etiology' of autism, after more than a decade of research, 'remains largely unknown' (Gupta and State, 2007: 429).…”
