Caffeine is the psychoactive drug most consumed in the world and also that it has the best use socially accepted, however, in the long run, its effects go beyond making people more connected and less dispersed to carry out their tasks. A new study has shown that drinking too much coffee may be linked to a higher risk of developing dementia.

For the construction of the study, a team of researchers from the University of the South of Australia analyzed the medical records of more than 17 volunteers registered in the UK Biobank, an open-access database of medical data from british citizens. Among people who drank seven or more cups of coffee a day, there was a 53% increase in the risk of dementia.

And the risks go beyond dementia, researchers say, there is also a link between excessive coffee consumption and a higher prevalence of physical changes in the brain and other neurological diseases. The results frightened even the scientists themselves, as coffee is one of the most consumed beverages in the world.

"Taking all possible permutations into account, we consistently found that higher coffee consumption was significantly associated with reduced brain volume," said the study's lead author, neuroscientist Kitty Pham. "Essentially, drinking more than six cups of coffee a day can put you at risk for brain diseases like dementia and stroke."

one or two cups

Despite the correlation, researchers have yet to pinpoint why drinking too much coffee is linked to an increased risk of dementia and other brain problems. In addition, they consider that what can cause neurological problems is excessive consumption, that is, it is not necessary to stop drinking coffee, but it is good to consume it in moderation.

“The typical daily consumption of coffee is between one and two cups of standard coffee,” said study co-author Elina Hyppönen. “Of course, although unit measurements may vary, a few cups of coffee a day is generally a good thing. But if you're finding your coffee consumption rising to more than six cups a day, it's time to rethink,” added Hyppönen.
