If you were born in America between 1940 and 1990, you were exposed to leaded gasoline exhaust, lead paint, and a food supply with no meaningful testing. This takes eight minutes. It asks you where you grew up, what your home looked like, and what you ate. Then it runs a cognitive baseline screen on the measure that appears most consistently across the lead-cognition literature. You will know more about your exposure history when you finish than most people find out in a lifetime.
Lead's cognitive effects have no event, no diagnosis, no day you can point to. The neurons that should have connected when you were three simply did not, and by the time you are an adult there is nothing to compare against. This assessment gives you a first approximation: a risk score based on where and when you lived, and a processing-speed screen on the measure that is most sensitive to lead damage in the published literature.
8 questions about your home, habits, and history. Scored against NHANES risk factors. Tells you where your main exposure vectors are.
6 timed questions adapted from the same cognitive assessment that's been in the news. Memory, attention, abstraction. Not a diagnosis, a baseline.
Based on your scores, you get specific next steps, whether that's testing your dishes, getting a blood lead test, or talking to your doctor.
