There's some really early eye movement based detection too. Good to see this. As others point out it isn't a binary but a hugely variant spectrum, but there are some commonalities that at the very least suggest that a child receive further screening or prepare the parent to watch for other symptoms. Regardless of the type and spectrum position, a kid with an early diagnosis/warning seems much more likely to have a good outcome than one that gets one while in pre-school or kindergarten.
