Current Biological Theories of Causation
Today it is commonly accepted that autism is a neurobiological disorder that is present at birth or develops within the first 30 months of life. After almost two decades of research, the precise causes of autism remain unclear. The research on biological causes of autism has been fraught with contradictory and disappointing results; findings are rarely replicated and often do not add up to a coherent explanation. There are several clues concerning the underlying brain dysfunctions in people with autism, however, and the methods by which these brain dysfunctions may be transmitted. These clues will be discussed in this chapter.
