For the first time, a study presented "compelling evidence" that caffeine consumption is beneficial for memory.
Published in the issue of January 12, 2014 of the journal Nature Neuroscience, the study shows that consuming caffeine can improve memory and have a beneficial effect on capacity retention for up to 24 hours after consumption.
Research is considered an 'exclusive proof' that caffeine benefits to long-term memory because all involved participants took one tablet of 200mg of caffeine after seeing a series of pictures.
