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.

Researchers have found that a gene could help the brain heal itself after a stroke or any other head-related injuries.

The study, published in Cell Reports, suggested that a dose of the TRIM9 gene could reduce brain swelling after stroke, prevent damage following a blow to the head (concussion) or encephalitis, which is the inflammation of the brain.

In addition, in a lab model, the researchers from the University of Southern California found that older brains with low TRIM9 levels — or engineered brains missing the TRIM9 gene entirely — were prone to extensive swelling following a stroke.

On the other hand, when the team used a harmless virus to carry a dose of the gene directly into TRIM9-deficient brains, the swelling decreased dramatically and recovery improved, the findings further revealed.

It is unlikely that gene therapy delivered by viruses will become the go-to treatment for strokes, head injuries or encephalitis as the best shot at treating stroke is within the first 30 minutes to one hour, said lead author Jae Jung at the varsity.
