What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

Three Cups of Coffee a Day Could Keep Alzheimer's Away

What’s the Latest Development?

Based on a study conducted, drinking three cups of coffee a day can help stave off Alzheimer’s. According to researchers, people who had obtained mild cognitive impairment (MCI) or loss of memory and consumed caffeine had a lot lower chances of the condition turning into dementia. Scientists monitored a group of people between the ages of 65 and 88 years. They were tested for the levels of caffeine in their blood, and their cognitive ability over a two to four year period. The results indicated that the people who did not develop Alzheimer's had more caffeine in their blood than the people who went on to develop the disease. Since coffee is the most consumed source of caffeine, researchers believe a few cups of coffee a day can be healthy for the brain. However, there needs to be more intensive research to see the effect of caffeine in this area over a longer period of time. 

What’s the Big Idea?

The benefits of coffee could help people maintain good mental health for longer. According to the Alzheimer’s Society, “between 10-15 percent of people with MCI go on to develop dementia.” Studies have found a relationship between caffeine and cognitive abilities. Several cups of coffee contain 1200 ng/ml, and blood samples showed the people with MCI who later developed did not have this level of caffeine. Although this evidence indicates a positive for coffee consumption, researchers at the Alzheimer's Society say they are still not sure if there is a guarantee that it will prevent Alzheimer's.
