Michael Yassa, assistant professor of psychological and brain sciences in the Krieger School of Arts and Sciences at Johns Hopkins University, along with a team of researcher discovered that caffeine (~200mg, about 1 strong cup of coffee per day) has a positive effect on long-term memory. This research, published in Nature Neuroscience describes how caffeine was found to enhance tested memories for up to 24 hours after the caffeine was consumed.
“We’ve always known that caffeine has cognitive enhancing effects, but its particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans,” said Yassa, the senior author on the paper.
This research, sponsored by the National Institute on Aging and National Science Foundation may just have given us a pass to continue our national caffeine devotion in the hope of keeping memory sharp.
