In the US? Not really. Its sale is banned for use in cars. Wikipedia says there are a few exceptions for aircraft, farm equipment, and marine engines, but even in those fields I've never heard of it being used. It's also been pretty much phased out worldwide with a few tiny exceptions. What exactly are you referring to?
I'm referring both to avgas (there's a measurable effect in populations near airfields) and leaded automobile fuel in a few countries in the world.

There is a fairly significant amount of clinical evidence available (despite it being effectively banned from study for decades), but the vast majority of evidence available is anecdotal reports from users.
