I wonder, are we simply underdianosing the women with autism as usual?
And I wonder if there's a correlation between drinking diet sodas (as opposed to naturally sweetened?) and getting your children evaluated for autism (like, say - diet soda drinkers are on average wealthier, and that correlates with better access to healthcare and more parental involvement, thus reducing underdiagnosis of autism?)
Given how sensitive obstetrics are to even small risks and how prevalent aspartame is, I'd be surprised if there is a genuine causal link here of such strong statistical effect. I mean, how many people use zofran? And yet obstetrics we're limiting its use in pregnant women just for a very very small alleged increase in the risk of heart problems in the baby.
So, there’s a significant gender difference here, possibly with diagnosis but likely a deeper connection. Alternatively, it might impact both but this study didn’t have enough statistical power to notice the correlation.
Same happens with ADD. A lot of parents are diagnosed in hindsight when their child is diagnosed. “Wait my son had ADHD because he acts like this? I acted exactly like this.”
Inattentive is a bit of a misnomer, too—it's not that they can't hold attention on something, it's that they have a hard time controlling where their attention goes. This is another reason why this presentation often flies under the radar: "my {daughter/son} can't have ADHD, {she/he} can stay focused on {favorite activity here} for hours!"
