The time frames seem a bit odd in their study and the most affected being born as late as 1986. Mainly because most vehicles in the US in the 1970’s ran on unleaded fuel already (ford didnt build a leaded vehicle past 74 or 75) and cars from the 70’s were lucky to be on the road a decade later. I would have thought the most effected would have been pre 1980. The US may not have banned it until 1996, but by that point 99% of cars touching the roads were already lead free.
