Emphasise the fact it is brain injury

I think that using the medical term "neurological" somehow obscures the plain fact that autism most probably starts in a form of brain injury. If parents and members of the public could understand a little of how detailed and complicated the brain "machinery" is that allows "normal" people to have a good enough level of intelligence, speech and social skills, they might begin to realise that an exact explanation of all autism is unlikely and maybe impossible. It seems reasonable that there is a genetic component in some families as there are similar personalities in families- which means brains are rather alike. When one tiny, critical part of the brain goes wrong you get families with, for example(in real life,two highly intelligent parents, one child becoming an internationally renowned scholar, another working for Google and a third who is quite autistic (although very bright with similar abilities to his brothers). It would be a good idea to tell people that preventing autism is extremely unlikely, even within families.
