Exposure to air pollution during pregnancy may lead to cognitive impairment: study

Press Trust of India  |  London 

Exposure to residential during pregnancy may lead to in children, a study warns.

According to the research, published in the journal Biological Psychiatry, the levels related to brain alterations were below those considered to be safe.

"We observed brain development effects in relationship to fine particles levels below the current EU limit," said from for Global in Spain.

This finding adds to previous studies that have linked acceptable levels with other complications including cognitive decline and foetal growth development.

Exposure to fine particles during foetal life was associated with a thinner outer layer of the brain, called the cortex, in several regions.

The study showed that these brain abnormalities contribute in part to difficulty with inhibitory control - the ability to regulate self-control over temptations and impulsive behaviour - which is related to mental problems such as addictive behaviour and

The researchers assessed air pollution levels at home during the foetal life of 783 children in

The foetal brain is particularly vulnerable during pregnancy - it hasn't yet developed the mechanisms to protect against or remove environmental toxins.

The findings of the study suggest that exposure to levels even below those considered safe could cause permanent brain damage.
