How prenatal alcohol exposure affects children's brain development and thinking

Brain and Cognitive Development in the PASS Cohort: The Impact of PrenatalAlcohol Exposure

NIH-funded research Children's Hospital of Los Angeles · NIH-11378222

This project looks at how drinking during pregnancy relates to brain scans, thinking skills, and facial features in children and teens from the PASS birth cohort.

What this research studies

Younger participants from the PASS birth cohort in South Africa who were previously studied and new participants will be invited for brain MRI scans, cognitive testing, and facial imaging. The team will oversample children whose mothers reported higher amounts of alcohol use during pregnancy to cover a wide range of exposure. About half of the earlier-scanned children will return for follow-up so researchers can see changes across adolescence (roughly ages 8–17). Findings will compare children with prenatal alcohol exposure to non-exposed peers to better understand links between exposure, brain development, thinking skills, and facial measures.

Who could benefit from this research

Good fit: Ideal participants are children and adolescents (about 8–17 years old) from the PASS cohort whose mothers reported drinking during pregnancy, including both previously studied kids and newly recruited youth, with non-exposed controls also included.

Not a fit: Pregnant people, adults without relevant prenatal exposure history, or children outside the PASS cohort and age range would not be eligible and likely would not directly benefit from participating.

Why it matters

Potential benefit: If successful, this work could help identify how prenatal alcohol exposure changes brain development and point to earlier detection and better support for affected children.

How similar studies have performed: Previous neuroimaging work by this team and others has linked prenatal alcohol exposure to brain and cognitive differences, but expanding to higher exposure levels and following adolescents over time adds new, less-tested information.
