Autism is caused by poor attachment?

[LosPollosHermanos17]

I have recently been involved in therapy that says autism is caused by poor attachment with the parents causing all the symptoms. I thought this was an outdated theory. Just wondered what other people think of this?

Human behaviour is naturally limited in its presentations so it's obvious that some things might superficially resemble others or have overlaps.

A diabetic hypoglycaemic attack can resemble being drunk for example.

A state of mania might resemble the effects of an illegal drug.

I wasn't neglected as an infant and I had a normal life up until around four when I lost my parents and was emotionally deprived from then on. The clinical psychologist who conducted my autism assessment was quite clear that there are easily identifiable differences between deprivation/attachment problems and autism. They can test for these differences. It's not rocket science. These French so called experts are peddling dangerous myths.

I encountered a camhs psychologist who was peddling this bollocks a few years ago. I ended up by having a meltdown in his office because I knew exactly what he was getting at and he didn't realise that I knew what he was getting at
