PFAS effects on brain reward and pleasure

PFAS induced alterations in reward processing

NIH-funded research Purdue University · NIH-11226571

This project looks at whether early-life exposure to PFAS chemicals changes how the brain experiences reward and pleasure in animals and people.

What this research studies

The team will study both animals and human samples to see if PFAS exposure changes brain circuits that control reward and causes symptoms like loss of pleasure (anhedonia). They will first set mouse PFAS doses based on PFAS levels measured in human brains to create a brain-relevant dosing plan. Mice will then undergo behavioral tests for reward-related responses and laboratory measures of neurotransmission. Human brain samples and clinical data will be compared with the animal results to link lab findings to people.

Who could benefit from this research

Good fit: Adults (18+) with documented or suspected early-life PFAS exposure or adults reporting reduced ability to feel pleasure (anhedonia) may be relevant for the human parts of this work.

Not a fit: People without PFAS exposure, children (if the human work focuses on adults), or those with unrelated medical issues may not directly benefit from this project.

Why it matters

Potential benefit: If successful, this work could reveal a link between PFAS exposure and mood or reward problems, which could guide prevention, diagnosis, and future treatments.

How similar studies have performed: Some animal studies and preliminary data suggest PFAS can alter neurotransmission, but human evidence on long-term effects on reward-related mental health is limited and this translational approach is relatively novel.
