I decided to look at mentions of language for Down syndrome,for example:
This shows the relative decline of 'mongolism' and 'retard' and the increase in more use of the word 'idiot' as a non technical term with general social acceptability. Down syndrome unsurprisingly has grown in use since the 1970s as mongolism fell away.

I suspect this increase in mentions tracks screening in pregnancy, unfortunately most terms used in relation to this are too general to track accurately. One additional comparison is interesting - if we add in autism in comparison, which far exceeds any recent mentions of Down syndrome:
