Environment Hold your breath. PAHs, or polycyclic aromatic hydrocarbons, are widespread pollutants formed when organic materials are incompletely burned.

They originate from vehicle exhausts, burning coal and oil, waste incineration, and wildfires. They can also be found inside the home, for example from tobacco smoke or open fires and stoves.

The initial study recruited more than women in the third trimester of pregnancy from New York City minority communities. They completed questionnaires and were given portable pollution monitors for 48 hours to allow researchers to determine their exposure.

Their children were then assessed between the ages of three and seven, and the team found that exposure was associated with symptoms of ADHD attention deficit hyperactivity disorder and other cognitive and behavioural problems including reduced IQ, anxiety and depression.

For the latest study40 of the same children had their brains scanned, revealing a strong link between PAH exposure in the womb and a reduction of white matter in the brain.

Brain white matter is made of millions of cells called axons that allow rapid connections between different regions of the brain. The study found an association of areas of reduced white matter with the processing speed of that part of the brain.

Yellow, red and orange show areas where white matter had affected the processing speed of that part of the brain. There was a stronger correlation in the left side of the brain.

For example, one study of Californian children showed that those exposed to the highest levels of traffic-related air pollution during pregnancy and in the first year of life were more likely to develop autistic spectrum disorders than those exposed to the lowest levels.

More direct evidence that air pollution affects the developing brain comes from animal studies.

One study of the brains of young mice exposed to ultra-fine particles at concentrations similar to those found in rush-hour traffic found the mice displayed enlarged cavities in their brains — a condition which in humans is associated with autism and schizophrenia.

Particles — Bad News For The Brain The mechanism by which air pollution is toxic to the brain is not yet fully understood, in particular, the pathway to the brain of particulate matter PM — small pollutants particles which can carry PAHs on their surface.

Ultrafine particles are believed to move to the brain either by travelling from the lung into the systemic circulation and across the blood brain barrier or by landing at the back of the nose then travelling to the brain via the olfactory nerve.

Once in the brain, pollutant particles can cause inflammation and cellular damage. Need For More Research As with any scientific project, there were limitations to the study: The researchers plan to scan many more children, and to assess the way PAH interact with other contaminants and their effects on the brain.

Cough cough — air pollution in London in This study and much of the other research on air pollution and the brain originates from the US, where the proportion of one major source of urban air pollution — the diesel-powered car — is low compared to the UK.

This makes it necessary to collect our own data here. The Cost Of Air Pollution Although there has been relatively little research on the negative effects of air pollution on the nervous system, evidence is already mounting.

A unique feature of air pollution as a risk factor for disease is that exposure is almost universal. Importantly, the study showed that the more the mother was exposed to PAH while pregnant, the larger the white matter disturbance in the child.

If further studies find similar results, the public health implications are significant given how widespread PAHs are and how little we know about the causes of mental health problems — an area that presents a large and growing disease burden on society.

The ever-accumulating evidence that so many components of air pollution contribute to such a diverse set of diseases confirms the urgent need to manage the quality of the air we breathe. Achieving this promises to be a significant and cost-effective way of improving our health and quality of life.A Kaiser Foundation study showed that elementary aged children use on average hours per day of entertainment technology, 75 percent of these children have TV's in their bedrooms, and 50 percent of North American homes have the TV on all day.

persistent fear and anxiety. can affect Young children’s learning and Development. working paper. 9. 9. members. the effects of stress on the development of brain architecture comes from animal studies, strong Persistent Fear and Anxiety Can Affect Young Children’s Learning and Development.

1. How chronic stress can affect the brain's size, structure, and how it functions. Although Facebook, YouTube, and Twitter, did not exist a mere decade useful filter in which to examine the social cognitive effects of digital media on today’s teenagers.

As iGeneration youth primarily socialize online, their “self efficacy” is spoke of the imbalance now happening in human brains, wherein left brain hemisphere. According to the article 'Digital power: exploring the effects of social media on children’s spirituality', children consider the Internet as their third place after home and school.

One of the main effects social media has had on children is the effect of cyber bullying.
