What they found
Developmental exposure to endocrine-disrupting chemicals (EDCs) and persistent organic pollutants (POPs) can reprogram endocrine and neural circuits, leading to persistent behavioral alterations and increased addiction vulnerability. This occurs through a "two-hit" model, where early exposure primes the system for later drug/stress impacts.
What they studied
This review synthesizes evidence from animal models and human epidemiological studies, focusing on how prenatal exposure to chemicals like BPA, phthalates, PCBs, and PBDEs impacts neurodevelopment and increases addiction-relevant endophenotypes.
Takeaways
The findings support risk-assessment strategies that consider sequential environmental and drug exposures, highlighting the importance of developmental timing, sex, dose, genetic background, and co-exposures.
About this paper
This is a review article synthesizing mechanistic evidence from animal models and epidemiological studies. It underscores the limited availability of longitudinal data directly linking early exposure to clinically diagnosed substance-use disorder (SUD) outcomes.
