EPA Impairs Brain Vessel Repair After Repeated Mild Head Injuries

4/30/2026

Summary

Story summary

Researchers led by Onder Albayram reported EPA impaired blood-vessel repair after repeated mild head injuries in mice.
EPA reduced angiogenesis-gene expression and weakened new microvascular network formation in the injured mice.
Human brain microvascular endothelial cells exposed to EPA showed slower wound closure and fewer tight junctions.
Brain tissue from six men with chronic traumatic encephalopathy showed elevated EPA and DHA and similar metabolic disruptions, but causation was not proven.
