What this research studies

This project follows a large group of mothers and their children so you can see how infections in pregnancy might relate to brain scans and behavior in adolescence. Researchers will combine trimester-by-trimester records of maternal infections and inflammation markers with brain imaging of the children in their teens and detailed behavioral and psychiatric assessments. The team uses the Generation R cohort, a long-term population study with many participants and repeated follow-up visits. They will look at timing, type, and severity of maternal immune activation to pinpoint links to adolescent brain differences and mental health outcomes.

Who could benefit from this research

Good fit: The work is most relevant to pregnant people and their children, especially those with documented infections or inflammation during pregnancy or adolescents with neurodevelopmental or psychiatric concerns.

Not a fit: People seeking immediate clinical treatment for existing psychiatric conditions are unlikely to get direct, immediate medical benefit from this observational research.

Why it matters

Potential benefit: If successful, the work could help identify pregnancies at higher risk and guide earlier monitoring or prevention to protect children’s brain development.

How similar studies have performed: Animal studies consistently show maternal immune activation can change offspring brain and behavior, and smaller human studies suggest similar links but larger, longer-term data have been limited.
