Microplastics and Parkinson’s Disease: 6 Plausible Brain-Risk Pathways

by GLOOM

MHD featured image for microplastics and neurodegenerative disease mechanisms.

A 2026 mechanistic review linked microplastics to 6 proposed Alzheimer’s disease pathways and 6 proposed Parkinson’s disease pathways.1 The calibrated interpretation is that microplastics are biologically plausible brain stressors, but the human evidence does not yet prove that they cause Parkinson’s disease or Alzheimer’s disease. Research Highlights Exposure is widespread: the review cited an estimate …

Microplastics & Nanoplastics Cross Blood-Brain Barrier within Hours & May Cause Damage

by GLOOM

Microplastics and nanoplastics (MNPs) from the breakdown of plastic materials pollute the environment and make their way into the human body, raising concerns over potential health impacts. Research shows that microplastics and nanoplastics are able to cross the blood-brain barrier in mice within 2 hours of ingestion. Key Facts: Polystyrene nanoparticles with a size of …
