Microplastics block blood flow in the brain, mouse study reveals

Nature 2025 11 citations

AI summary Read the abstract

Researchers used real-time imaging in mice to demonstrate that microplastics can accumulate inside cells, causing them to form clumps that block blood flow in the brain and impair movement. The findings provide direct visual evidence linking microplastic ingestion to cerebrovascular obstruction and neurological effects in a mammalian model.

Microplastics block blood flow in the brain, mouse study reveals

AI summary Read the abstract

A mouse study using real-time imaging found that cells stuffed with microplastics can form clumps that block blood flow in the brain, affecting the animals' ability to move. This research raises concerns about potential neurological effects of microplastic accumulation in the bodies of mammals.

Your brain is full of microplastics: are they harming you?

AI summary Read the abstract

Researchers and science journalists report that microplastics have been detected in the human brain, lungs, kidneys, and other organs, noting that scientists are urgently studying what health effects these particles may cause, though the full consequences of internal microplastic accumulation remain poorly understood.

Presence of microplastics in carotid plaques linked to cardiovascular events

AI summary Read the abstract

Researchers found that patients with carotid artery disease who had detectable microplastics and nanoplastics within their carotid plaques faced a significantly higher risk of death or major cardiovascular events compared to patients whose plaques contained no detectable plastic particles.

Microplastics found in artery plaque linked with higher risk of heart attack, stroke and death

AI summary Read the abstract

Researchers report that microplastics found in arterial plaque are associated with significantly higher rates of heart attack, stroke, and death, adding to accumulating evidence that microplastic exposure may contribute to cardiovascular disease risk through mechanisms that are still being investigated.
