My guess is this is a Fetal Alcohol Syndrome adult.
Could be....back in the day, young docs and other health care workers used to describe non Down’s syndrome kids who looked a bit different as FLK’s....
Funny Looking Kids.....
It shows how little they knew about the specific causes of FLK’s...but I remember that some of the kids had deformed bodies, large or small heads, and neurological, behavioural issues. Pretty damn sad. One kid had to wear a football helmet, cause he would bash his head against walls, spontaneously. Hard to contemplate living like that.
