Coffee lovers rejoice! Researchers have discovered yet another awesome benefit we can attribute to the almighty java – dementia prevention.
The research, published in the Journal of Gerontology, states that women over the age of 65 who drink more than 261 milligrams of caffeine per day see a 36% reduction in dementia risk.
This aligns with a number of past studies – like this one – that have proven caffeine's mental benefits and speculated that it might provide protection against dementia.
"The mounting evidence of caffeine consumption as a potentially protective factor against cognitive impairment is exciting given that caffeine is also an easily modifiable dietary factor," said Dr. Ira Driscoll, lead author behind the Journal of Gerontology report.
Study authors recruited nearly 6,500 post-menopausal women for the study. The participants answered a variety of questions about their coffee consumption. Using their responses, researchers then split the women into two groups – those who consumed more coffee than average and those who consumed less.
Over the next 10 years, 388 of the study's participants developed dementia. Most of them were from the group with below-average coffee consumption habits.
Researchers aren't 100% positive but they suggest it may be because of the way caffeine blocks inflammation in the brain. Past studies have shown that brain inflammation is a major driver of dementia, including Alzheimer's – the most common form of the disease.
The coolest part? Through this very same mechanism, caffeine can also help those with existing mild dementia. As we discussed here, even those not at risk of developing dementia can reap caffeine's memory-boosting benefits.
One study from the University of California found that adults who consume caffeine before a memory test perform significantly better than those who don't.
