New York, Feb 1, 2017: Elderly women exposed to tiny air pollution particles may face an increased risk of dementia, including Alzheimer’s disease, a study has found.

The findings showed the fine particulate matter (PM 2.5) — coming from power and automobile plants — could invade the brain and wreak havoc in older women who live in these places.

The air quality of those places which exceeds the US Environmental Protection Agency’s standard of 81 percent were more likely to experience global cognitive decline.

These women were also 92 per cent more likely to develop dementia, including Alzheimer’s.

“Microscopic particles generated by fossil fuels get into our body directly through the nose into the brain,” said Caleb Finch, Professor at the University of Southern California (USC).

“Cells in the brain treat these particles as invaders and react with inflammatory responses, which over the course of time, appear to exacerbate and promote Alzheimer’s disease,” Finch added.

The effects were stronger in women who had the APOE4 gene — a genetic variation that increases the risk for Alzheimer’s.

For the general population, the risk was nearly 21 per cent, the researchers said.

The study also “provides the evidence of a critical Alzheimer’s risk gene possibly interacting with air particles to accelerate brain ageing,” said Jiu-Chiuan Chen, Associate Professor at the USC.

For the study, published in the Nature journal Translational Psychiatry, the team analysed data of 3,647 of 65- to 79-year-old women who did not have dementia.

In another experiment, the scientists chronically exposed female mice carrying the APOE4 gene to nano-sized air pollution for 15 weeks.

The results showed that the exposure of mice to air particles damaged neurons in the hippocampus — the memory centre vulnerable to both brain ageing and Alzheimer’s disease.

Vikas Maurya, senior consultant at Fortis, said preventive measures like avoiding outdoor physical activities like cycling, jogging or any other outdoor exercises should be taken.

He suggested that air purifying plants like Aloe Vera, Ivy and Spider Plant should be kept at home and in offices.

Fruits rich in Vitamin C, magnesium, omega fatty acids should be consumed more to fight any allergy or infection. “Have herbal ginger and tulsi tea in adequate quantity.”

The doctors said air pollution poses a major health risk and can cause stroke, heart disease, lung cancer, and chronic and acute respiratory diseases.

Islamabad, November 6, 2017 : Smog has enveloped much of Pakistan and neighboring India, causing highway accidents and respiratory problems, and forcing many residents to stay home, officials said Saturday.

Pakistani meteorologist Mohammad Hanif said the pollution, caused by dust, the burning of crops, and emissions from factories and brick kilns in Pakistan and neighboring India, was expected to linger until the middle of the month and contribute to smog- a combination of smoke and fog. He advised people to wear facemasks to protect themselves from respiratory ailments.

Mohammad Arshad, a highway police official, said at least 10 people were killed and 25 injured in road accidents linked to poor visibility in various parts of the Punjab province due to smog, since Monday. Authorities have advised people to limit road travel.

Average air pollution in Pakistan’s major cities is about four times higher than the World Health Organization limits.

Similar problems have been reported in the Indian capital, New Delhi, where air quality was rated “very poor” Saturday. Some private schools in New Delhi have suspended sports and outdoor activities.

India’s Supreme Court banned the sale of firecrackers in New Delhi ahead of last month’s Hindu Diwali festival to try to curb air pollution in the city notorious for smog. Though reports said air quality was better than last year, pollution levels in the capital hit 18 times the healthy limit the night after the festival, as many dodged the ban. (VOA)
