A quick cup of coffee may help to give you a quick memory boost, suggest recent study results. Researchers at the University of Arizona found that seniors who drank a 12-ounce mug of regular coffee just before taking a memory test performed significantly better than those who drank decaffeinated coffee. Furthermore, caffeine drinkers did not show any decline in performance on the tests throughout the day, whereas the performance of those given decaf for the experiment declined significantly when the test was performed once again in the afternoon. The researchers who carried out the study say that the results support those of other studies which suggest that caffeine can boost the memory and prevent it from flagging as the day progresses.
