Autism and the environment.
University of North Carolina School of Public Health, Chapel Hill, North Carolina, USA.
Speculation that the environment plays a role in the development of autism primarily comes from two observations: a) although concordance among monozygotic twins is high, it is not perfect, and a specific "autism gene" or set of genes has not yet been identified; and b) the prevalence of autism is higher than previously thought-if it is rising, the rise might be associated with a shift in the environment.
