Autism at the Crossroads: Determining the Phenotype Matters for Neuroscience, by Tony Charman
Contemporary research uses several approaches to define biological markers: one may search for the characteristics of the “autistic brain,” look for autism genotype(s), or investigate comorbidity and environmental influences (Nadesan 2005). Viewing autism as a brain dysfunction (Fombonne 2003, Freeman and Cronin 2002, Wing 1997), psychiatrists and neuroscientists have tried to discover the disorder’s “brain address” (Wickelgren 2005, 1856) and have even suggested that the autistic brain is an extreme form of the “male brain” (Baron-Cohen 2002).
In view of such heterogeneity, it has been proposed that autism is best understood as a “multi-system disorder” (Charman 2006).
