Pollution Causes Learning, Memory & Mood Problems

While the damaging effects of air pollution on the heart and lungs has been shown in previous studies, a new study suggests that the harmful impact extends beyond that. Long-term exposure to air pollution can lead to physical changes in the brain, as well as learning and memory problems and even depression.

LauraFonken and colleagues in Ohio State’s Department of Neuroscience collaborated with researchers in the university’s Davis Heart and Lung Research Institute for the new research.

“The results suggest prolonged exposure to polluted air can have visible, negative effects on the brain, which can lead to a variety of health problems,” Fonken said.

In other studies, some of the co-authors of this study from the Davis research center discovered that long-term exposure to polluted air causes widespread inflammation in the body, which is linked to a number of health problems in humans, including depression. The recent study found evidence that this low-grade inflammation is evident in the hippocampus.

“The more we learn about the health effects of prolonged exposure to air pollution, the more reasons there are to be concerned,” said Randy Nelson, co-author of the study and professor of neuroscience and psychology at Ohio State.

“This study adds more evidence of pollution’s negative effects on health.”

In the end, we conclude again that there's nothing good about pollution.

There are many readers here who say they have known these aspects of pollution since the 1970's. The pollution rates increase from year to year and that's why babies are born with toxic chemicals in their blood and they suffer from allergies right from the start of their litle lives. In a democratic society - YOU are the government, so change depends on you !
Where I live in BC, outside of Vancouver, there are many people who don't know anything about pollution and the effect it has on our groundwater and our overall health. With our environmental group, we bring education and sustainable change to our community. There is much work to be done and the Squamish authorities do not address noise pollution either.

I thought we had already reached these conclusions way back in 1970!

sooo...not much change then!
