Well...my DS is autistic and I had no paracetamol when pregnant.
With DD I had paracetamol when I was pregnant due to migraines, which I had a lot. She is not autistic.
So two children, one autistic - no paracetamol, one NT and paracetamol - surely this must prove it? (This is a joke btw).
Women have had paracetamol for decades, lots and lots of decades. It has been so widely used, for so long, that it is the only painkiller recommended for pregnancy due to it's safety profile (obviously no new drug can ever be recommended in pregnancy as it is unethical to test, paracetamol was used before ethical concerns).
Sure, autism was probably less diagnosed, but I think that cases have risen, but it is not paracetamol. It's as likely to be the rise in processed food, microplastics in food, the increased antibiotic and hormone use in animals that we eat/drink from.
Of course it may be the increase of screens having an effect on forming brains.
A lot of it is genetic.
It could be a correlation of all those things, or none.
It's certainly far more nuanced than PARACETAMOL CAUSES AUTISM, which is a catchy headline, but almost certainly bollocks!
