Study Summary

Carrying the APOE ɛ4 allele is the strongest genetic risk factor for developing Alzheimer's disease. The goal of this project is to identify whether carrying the APOE ɛ4 allele is associated with reduced delivery of DHA to the brain. This information will help us identify the target population that could benefit from DHA supplementation to prevent cognitive decline.
