At this point,
the cause of autism or the spectrum of ASD remain
unknown. Scientific evidence supports the conclusion that ASD is a
behavioural syndrome that results from various brain abnormalities. These
abnormalities develop as a result of genetic predispositions and early
environmental (likely to be the 1st trimester inside the utero) insults. The
genetic of autism is complex and up till now no genetic markers or biological
markers of the disorder has been reliably identified. Current postulation is
that the disorder is an expression of a heterogenic pool of genes instead of a
single or a couple of gene interactions.
Although in the last decade, there was an increase in interest in the
relationship between environmental toxins, diets and the disorder of autism, up
till now, there is no scientific evidence which demonstrate a causal
relationship between ASD and these toxins or diets.
