Story summary

A University of Rhode Island study indicates microplastics may cause Alzheimer’s-like symptoms in genetically predisposed mice.
Researchers exposed APOE4 and APOE3 mice to microplastics in drinking water for three weeks, resulting in notable cognitive decline.
Male APOE4 mice showed increased vulnerability in open spaces, while females struggled with novel object recognition.
The findings suggest a connection between environmental toxins and neurodegeneration, similar to human Alzheimer’s symptoms.
The Microplastics Safety Act seeks FDA investigation into health impacts, especially for vulnerable groups.
