It was previously proved that coffee consumption can help lowering the risk of mild cognitive impairment, but according to a new study published in the Journal of Alzheimer’s Disease the way in which one consumes coffee can on the contrary increase the risk of mild cognitive impairment.
Mild cognitive decline represents the decline of cognitive abilities such as thinking skills and memory and it is considered a risk factor for Alzheimer’s disease. Nearly 10 to 20 percent people in the US who are at least 65 years old may suffer from mild cognitive impairment.
The study was conducted on 1.445 people with ages between 65 and 84. They were monitored for a period of 3.5 years. The researchers looked at the incidence of mild cognitive impairment and their coffee consumption habits. The participants in the study were part of ILSA (the Italian Longitudinal Study on Aging).
The findings of the study indicate that healthy participants who increased their coffee consumption to more than one cup every day were two times more likely to develop mild cognitive impairment in comparison to those participants who reduced their coffee consumption to less than one cup per day.
Participants whose coffee consumption was moderate, meaning one or two cups of coffee per day, had fewer chances of developing mild cognitive impairment when compared to those who never consumed coffee or consumed it very seldom. But those participants who increased their coffee consumption over time were 1.5 times more likely to suffer from mild cognitive impairment than those participants who coffee consumption was stable, meaning no more than one cup of coffee per day.
The researchers did not find any noticeable connection between mild cognitive impairment and coffee consumption in the case of participants who had more than two cups per day in comparison with those participants who never or rarely drank coffee.
It is not yet clear what is the reason behind these results, but researchers speculate that caffeine might reduce the damage caused by a protein fragment which accumulates in the brains of those who suffer from Alzheimer’s disease, that is beta-amyloid.
The researchers involved in the study 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 Alzheimer’s disease.”
