Researchers at the Johns Hopkins University in US have found the first clear proof that proves caffeine is capable of boosting certain memories for at least up to 24 hours after its consumption.

From a very long time, caffeine is famous as energy drink that can help a person to stay awake.

“Caffeine’s particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans until now”, says Dr. Michael Yassa, lead researcher and assistant professor of psychological and brain sciences at Johns Hopkins University in Baltimore.

Over 100 people took part in the study. These people did not eat or drink caffeinated products often and were shown a sequence of pictures. After five minutes, the participants were separated into two groups. One of the groups was given a placebo and the other group was given 200-milligram caffeine pill.

The next day, both the groups were shown pictures. It was found that both the groups correctly recognized images as old and new. However, the group that was provided caffeine was superior in finding out the similar images. This proved that caffeine can improve functioning of memory up to 24 hours after its consumption.

The next milestone to achieve in the study was to find out mechanisms responsible this improvement.

The findings are published in the journal Nature Neuroscience.
