Microplastics in the brain may be linked to dementia risk
A Japanese article describes research suggesting tiny plastic particles can build up in the brain.
The particles, known as microplastics, can come from everyday plastic products, including bottled drinks.
Researchers detected an amount in the brains of deceased people that the headline compares with the size of a crayon.
The findings raise a possible link between microplastics and dementia risk, but do not establish that plastic causes dementia.
The article says the effects of these particles and possible ways to reduce exposure are being considered.
It gives no specific next steps or further research plans.
A Toyo Keizai article says microplastics may accumulate in the brain and could be related to dementia risk.
The article reports that microplastics equivalent to about one crayon were detected in the brains of deceased people.
It raises the possibility that plastic bottles and everyday plastic products contribute to exposure.
The article is by Takayoshi Shimohata, a professor of neurology at Gifu University’s Graduate School of Medicine.
