A new study published in the Journal of Alzeheimer’s Disease examined the connection between coffee drinking habits and cognitive functions among adults. The research analysed a group of 1,445 subjects aged 65-84 years old from the Italian Longitudinal Study, a population-based sample from eight Italian municipalities that included 5,632 subjects in total, and concluded that keeping a moderate and consistent usage of caffeine held the lowest risk for developing mild cognitive impairment (or MCI).
Cognitively normal adults who regularly drink one or two cups of coffee a day were found to have a reduced rate for developing MCI, whereis those who never or rarely drank coffee actually had a higher possibility for the mild cognitive impairment, according to Vincenzo Solfrizzi from the University of Bari Aldo Moro and the other authors of the study.
“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.” read the study.
MCI is widely considered an early stage of Alzheimer’s disease and dementia, and since there is not yet any effective treatment to correct this neurological disorder, identifying the factors which can lead to or slow down the condition is a crucial part of discovering a remedy. Caffeine has constantly been in the scientific spotlight as there have already been many studies exploring its potential improvement of cognitive performance, and also because it is one of the most regularly consumed beverage around the world.
“More sensitive outcomes such as findings from neuroimaging studies should become available from experimental data, so further explaining the mechanisms underlying the neuroprotective effects of coffee, tea, and caffeine consumption,” the research concluded. “Larger studies with longer follow-up periods should be encouraged, addressing other potential bias and confounding sources, so hopefully opening new ways for diet-related prevention of dementia and AD.”
