Scientists have discovered small air pollution particles in the brains of young people, which are said to damage cells like Alzheimer’s and Parkinson’s disease.
As part of the study, 186 dead young people, including young children from Mexico City, were brainwashed, which was published in the journal Environmental Research.
The researchers warned that they could further affect molecules such as Alzheimer’s and Parkinson’s, warning that small air pollution particles were found in the brains of everyone studied.
Evidence of pollution is located in the substantia nigra – an area of the brain that is crucial to the progression of Parkinson’s disease. The team believes that particles associated with Alzheimer’s and Parkinson’s, and particles found in the brains of young subjects, could enter the human system through the nose or intestines.

Meanwhile, they could not be found in the brains of people in less polluted areas than Mexico City, which is known for smoking and increasingly dangerous ecological conditions.
The study is still under observation, said Barbara M. Thar, a professor at Lancaster University who was one of the authors of the paper, he told the Guardian. However, he said the new findings give further credit to the theory that there is a direct link between neurodegenerative diseases and pollution.
“We haven’t been able to prove the causality so far, but how can you expect these nanoparticles that have that metal species to sit numb and harmless inside the serious brain cells?” It’s a smoking gun – it seriously looks like it’s running nanoparticles pills that are causing the observed neurodegenerative damage. “
If correlation is confirmed it could be a major concern for humanity as about 90 percent of the world’s population lives in areas where air pollution levels exceed the World Health Organization’s limits. The organization’s 2016 report states that about 3 million deaths each year are linked to the effects of air pollution.

Alzheimer’s is a chronic neurodegenerative disease that causes dementia, language problems, mood swings and other problems. Parkinson’s mainly affects the motor system, manifesting itself in vibrations, sluggishness and stiffness of movement and other things. Both conditions are more common for older people.
