Can partial ASD (Autistic Spectrum Disorder) be explained by the way other children treat them as a result of their differences and by their medicalised experience?

The simple answer would be no. ASD caused purely by the way a child is treated or by the way their peers treat them is not something that we see. ASD is a different kind of problem to that. Of course, the way a child is treated can exacerbate an underlying vulnerability and that can bring things out or make them worse but as a primary cause we don’t see that, no.
