Research published in Nature Medicine reveals that microplastics are accumulating in the human brain at unexpectedly high levels, with much higher concentrations observed in brains from patients with dementia.
While this data does not prove causation, the consistent association and biological plausibility suggest that microplastics may contribute to brain inflammation and dementia risk. Understanding sources of exposure and strategies for reduction may offer a way to protect brain health.
For more nuances, see the deep dive linked above.
