A new study found dramatic increases in microplastics in recent human brain samples compared to brains from just eight years ago. The study, published Monday in the journal Nature Medicine, analyzed 24 brains of people who died within a few months of January 2024.

A new study shows that microplastics are making their way into our brains, and that their concentrations are rising.

Human brains today contain 50% more plastic than in 2016, a new study found. Brain of people diagnosed with dementia had the most.

A new study finds that microplastics and nanoplastics accumulate at higher levels in the brain than in the liver and kidney.

People with dementia have 10 times higher levels of microplastics in their brains than other humans, the study shows, but whether that is a cause of dementia was not part of study. Most plastic gets into humans indirectly through the food we eat, Campen said.

Tiny plastic particles hidden in food, water and even in the air have been found inside human brains, accumulating at an alarming rate. A new study has found microplastics – plastic pieces less than five millimetres long – at higher levels in the brain than in the liver and kidney.

Researchers studied samples of human brains and found high levels of microplastics, but it's unclear how they slip past the blood-brain barrier.

Researchers at the University of New Mexico found the average brain has the equivalent of about 7 grams of microplastics — 50% more than studies revealed in 2016. The potential health implications are still unclear.
