Air pollution exposure in first 5 years of life puts children at risk of brain disorder
According to the team led by the Barcelona Institute for Global Health (ISGlobal), the greater the risk of a child before the age of five, the greater the change in brain structure in adolescence.
“The novelty of the current study is that it identified periods of susceptibility to air pollution. We did better by analyzing the data on a month-by-month basis, in contrast to previous studies in which the data were analyzed for trimesters.” measured the risk using a time scale, about pregnancy or childhood years,” said Anne-Claire Binter, ISGlobal researcher and first author of the study.
In this study, “we analyzed children’s exposure to air pollution on a monthly basis from conception to age 8.5,” Binter said.
In addition to an association between air pollution and white matter microstructure, the study also found a link between specific exposure to fine particulate matter (PM 2.5) and the amount of “putamen,” a brain involved in motor function, learning processes. is structure. and many other tasks.
Abnormal white matter microstructure has been associated with psychiatric disorders (depressive symptoms, anxiety and autism spectrum disorders).
