Story summary

A University of Rhode Island study indicates short-term microplastic exposure may raise Alzheimer's risk in genetically modified mice.
Mice exposed to polystyrene microplastics exhibited behaviors similar to Alzheimer's symptoms, including memory problems.
Researchers emphasize that while APOE4 is a key risk factor, it does not ensure Alzheimer's development. Additional research is necessary to assess human impacts.
