This epidemiological study confirms that the quality of the air is an integral part of the genesis of neurodegenerative diseases.
Study developed by St. George's University and Kings College in London and published in the British Medical Journal (BMJ). , found evidence of a positive badociation between air pollution levels in different residential areas of said city and diagnoses of dementia.
The study involved 130,978 Londoners aged 50 to 79 years with no signs. surveillance began in 2005. They lived in different areas of Greater London, close to industries and major highways, and its evolution was observed until 2013.

These manifestations of dementia are not related to other possible factors, such as smoking or diabetes, although they link the data of contamination to various types of dementia, the only one that appears clearly is Alzheimer's Disease
This epidemiological study confirms that air quality is an integral part of the genesis of neurodegenerative diseases, as well as other factors such as smoking or sedentary lifestyle. Source: ElCiudadano.cl
