We are what we breathe, and the smog is to change the structure of the brain of children
The air pollution caused by traffic is associated with adverse effects on cognitive development, behavioural and psychomotor of children, already knew, but now a new study published in Plos One says that it is able to change the structure of brain . In particular, to reduce the 3-4% of the volume and thickness of certain areas involved in motor control and sensory perceptions, such as sight or hearing.
early Exposure to The authors of the survey - a study conducted at Cincinnati Children's Hospital, have discovered that the brain of those who at one year of age is exposed to a high level of air pollution due to traffic in 12 years has a volume of gray matter and the thickness of the cortex lower than children with lower levels of exposure. Using magnetic resonance imaging to obtain anatomical images of the brain structure, the researchers verified that the volume of the lobes of the frontal and parietal and the cerebellum of the 12enni more exposed to high rates of pollution in the first year of life was down 3-4%. A percentage that “even if much lower than that you could check for a degenerative disease - is to know in a note to the Cincinnati Children's Hospital Travis Beckwith, first author of the work - may be sufficient to influence the development of different physical and mental processes".
you are also what you breathe and where you live, The twelve year old boys involved in the investigation were 147, and they all were enrolled in the Study on allergy and air pollution in the pediatric age group of the Cincinnati Children's Hospital, a large longitudinal study set up at the beginning of the years 2000 to analyze in time the relationship between exposure to pollution from traffic and health outcomes. All study participants were subjected to medical examinations at the age of 1, 2, 3, 4, 7 and 12 years while they were exposed to different levels of traps in the course of their first year of life. Researchers have crosschecked and evaluated, with statistical analysis of the elements that emerged from the images obtained with resonance and those on the exposure, collected using a network of air sampling at the level of 27 sites in the Cincinnati area. The results of the study “although exploratory, has stated Travis - suggest that the place where you live and the air you breathe may affect development of the brain.”
