The study, published in the journal Science Advances, shows how small particles of plastic ingested through water, food and even the air can contribute to the buildup of alpha-synuclein, a protein linked to these diseases.
The experiments were carried out in three different models: in test tubes, in cultured nerve cells, and in mice with Parkinson’s disease. The results showed that polystyrene nanoparticles, often used in disposable cups and plastic cutlery, increase the risk of developing Parkinson’s disease.
This discovery highlights the importance of properly recycling plastics and combating microplastic pollution, which not only harms the environment but can also have serious consequences for human health.
Previously, researchers from the University of Rhode Island also found that microplastic accumulation in the brain can lead to behavioral changes in animals, especially older animals.
