Increasing coffee intake bad for your brain : Study

London: While drinking your daily cup of coffee can help you stay sharp, modifying your habit by increasing coffee consumption over time may increase risk of mild cognitive impairment (MCI), early symptoms of Alzheimer’s disease (AD) and dementia, says new research. 14599057004_9dc53af6f9_b

“These findings from the Italian Longitudinal Study on Ageing suggested that cognitively normal older individuals who never or rarely consumed coffee and those who increased their coffee consumption habits had a higher risk of developing MCI,” said one of the researchers Francesco Panza from the University of Bari Aldo Moro, Bari, Italy.

“Therefore, moderate and regular coffee consumption may have neuroprotective effects also against MCI – confirming previous studies on the long-term protective effects of coffee, tea, or caffeine consumption and plasma levels of caffeine against cognitive decline and dementia,” Panza noted.

The study involved 1,445 individuals aged 65-84 years.

An interesting finding in this study was that cognitively normal older individuals who modified their habits by increasing with time their amount of coffee consumption ( more than a cup of coffee/day) had about two times higher rate of MCI compared to those with reduced habits (less than a cup of coffee/day).

They also had about one and a half time higher rate of MCI in comparison with those with constant habits (neither more nor less than one cup of coffee/day).

Moreover, those who habitually consumed a moderate amount of coffee (one or two cups of coffee/day) had a reduced rate of the incidence of MCI than those who habitually never or rarely consumed coffee.

These findings were published in the Journal of Alzheimer’s Disease.

Exposure To High Levels of Air Pollution May Lead To Changes Children’s Brain Structure

Previous studies of traffic-related air pollution suggest that it contributes to neurodegenerative diseases and neurodevelopmental disorders

Exposure to high levels of traffic-related air pollution at age 1 may lead to structural changes in the brain at the age of 12 which can influence the development of various physical and mental processes, warns a study.

The researchers found that children with higher levels of air pollution exposure at birth had reductions at age 12 in gray matter volume and cortical thickness as compared to children with lower levels of exposure. Gray matter includes regions of the brain involved in motor control as well as sensory perception, such as seeing and hearing. Cortical thickness reflects the outer gray matter depth.

The study, published online in the journal PLOS One, found that specific regions in the frontal and parietal lobes and the cerebellum were affected with decreases on the order of three to four per cent. “The results of this study, though exploratory, suggest that where you live and the air you breathe can affect how your brain develops,” said lead author of the study Travis Beckwith, PhD, a research fellow at Cincinnati Children’s Hospital Medical Center in the US.

“While the percentage of loss is far less than what might be seen in a degenerative disease state, this loss may be enough to influence the development of various physical and mental processes,” Beckwith said. For the study, the researchers used magnetic resonance imaging to obtain anatomical brain images from 147 kids.

These children are a subset of the Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS), which recruited volunteers prior to the age of six months to examine early childhood exposure to traffic-related air pollution and health outcomes.

The volunteers in the CCAAPS had either high or low levels of pollution exposure during their first year of life. The researchers estimated exposure using an air sampling network of 27 sites in the Cincinnati area, and 24/7 sampling was conducted simultaneously at four or five sites over different seasons.
