Summary

This study screens up to 5,000 healthy volunteers and people at risk for psychiatric or neurodevelopmental disorders like autism. Participants undergo interviews, cognitive tests, and other evaluations to see if they qualify for future research studies at NIH. The goal is to build a pool of well-characterized individuals for deeper investigations into brain and behavior conditions.
