I suspect that microplastics are not reaching the brain. We have autopsies that can specifically look for this. Example: "Researchers found evidence of plastic contamination in tissue samples taken from the lungs, liver, spleen and kidneys of donated human cadavers." https://www.upi.com/Health_News/2020/08/17/Autopsies-show-microplastics-in-all-major-human-organs/4221597672641/ https://www.upi.com/Health_News/2020/08/17/Autopsies-show-mi...
