Scans reveal how pollution can change the brain chemicals of anxious children


Air pollution from car exhaust bugs can be changing children's brain structure to make them more concerned, new research suggests.

Researchers have identified higher rates of mental illness, learning and developmental delay (not to mention asthma and obesity) among children growing up near troublesome shores.

For the first time, however, Cincinnati University scientists have seen signs of those changes, using neuroimaging.

Those who were vulnerable to pollution had higher volumes of fetabolite which had to link with Alzheimer's disease and brain disease.

And the same children had higher rates of short-term anxiety, giving the scientists an idea of ​​one way that pollution could affect the brain to increase the risks of mental illness.

The brain scans of children that come into contact with higher levels of pollution show changes to their chemicals and their structures in the brain that could explain their higher anxiety rates.

Over 40 per cent of Americans live in cities and towns with unhealthy air pollution levels.

Fine particles, short-term pollution, long-term pollution and ozone are all bad for people of all ages in a number of ways, including raising risks for asthma diseases, the heart and lungs and diabetes.

But the development of fetuses, babies and children is particularly at risk from pollution because their lungs and brains are still developing.

The World Health Organization estimates that 700,000 children under five die each year due to air pollution.

Children's lungs do not grow as big or so strong in highly polluted areas.

And that minor issue of the sky can travel from their lungs to the brain and damage protective membranes there.

Studies consistently show that children growing up in smoky air perform more badly on cognitive tests, have higher rates of ADHD, autism and other behavioral disorders.

A study in the Netherlands of nearly 800 children aged six to 10 years last year found signs that those exposed to pollution had changed their brain cords.

These outer parts of the brain are essential to stimulate the control – a function that many children with behavioral disorders have a impairment.

But as children are not only suffering behavioral problems but mood disorders in a more corrupt world, researchers at the University of Cincinnati wanted to investigate what changes the air quality could be associated with. The brain is being implemented.

To do this, they performed scans in the brain that reveal the chemical composition of brain tissue on 14 children.

The research team also assessed the children on the basis of a standard concern and established how much pollution they had been exposed to during their lifetime and in the previous year by referring to air pollution measures from the areas. where the children lived.

Results from the chemical brain scans revealed marked differences in the chemical levels of the myo-inositol name in the brain of children who had lived in the poorest air quality.

Myo-inositol is a common fetabolite of glucose – the molecule that gives energy to cells – in bodies of humans, other mammals and even in plants.

Its effects are rather Jekyll-a-Hyde: it appears to be beneficial in treating republican ovarian symptoms and helping to improve stroke results and perhaps mood disorders in adults, but can high levels of the metabolite. be a sign of the pre-dementia period too. of Alzheimer's disease.

There has long been suspicion that inflammation is corrupt normal brain structures and behaviors, and it is thought that glial cells, which surround and insulate neurons, play an important part in this inflammatory response.

Cincinnati University researchers suspect that the higher levels of myo-inositol in these cells may be linked to pollution, causing inflammation and, in turn, raising risks for anxiety.

The leader of the study, Dr Kelly Brunst, suggested that there could be a link between TRAP (air pollution associated with traffic), metabolic deregulation in the brain and symptoms of general anxiety in children who are healthy. otherwise, &; he said.

In particular, the more pollution they were exposed to and more recently they were exposed to, the more symptoms of anxiety children displayed.

These were only short term exposures and symptoms levels, but they could be a coal mine.

I think it can talk about a greater impact on the health of the population… that more exposure to air pollution can trigger a meningitis response, as is evident in the progress we have seen in my life. -inositol, & # 39; said Dr Brunst.

This can show that some populations are more at risk for worse anxiety outcomes.
