Daily Mail health headline again:
Is this what causes autism? Brain injury in the womb might be root of the disorder according to new research
Autism is a symptom much more than it is anything else. And it’s certainly possible that brain injury could cause it: brain injury can do all sorts of strange things like make people talk with a Scots’ accent (err, no, not saying that all who do so have brain injuries, despite that being a useful explanation for Glasgow. Rather that people who are not and never have been Scots have been recorded as not having Scots accents before injury and having one after).
But we know absolutely that there is a genetic component to much of what we record as being autism. It runs in families, it’s more prevalent in males than females….these aren’t consistent with foetal brain injury being the only or even most prominent cause.
