Two espressos enhance long-term memory

Topics: Health Issues

Although coffee has long been a friend of students studying through the night, a new study by Michael Yassa, a neuroscientist at the University of California, shows it does more than just keep one awake - it's the first convincing evidence that caffeine enhances long-term memory in people if the dose is provided the dose is 200 milligrams ... the amount in two espressos (espressos contain a higher concentration of suspended and dissolved solids than regular coffee):

[...] caffeine enhances long-term memory by improving the process of memory consolidation. "This doesn't mean people should only drink coffee after they've studied, and not before," says Yassa. "I think you would get the boost regardless." That's because the process of consolidation is likely to begin as soon as new memories form.

However, caffeine isn't much use once consolidation is finished. The team ran a second experiment in which caffeine wasn't administered until one hour before the memory test, to check for any effects on memory retrieval. They found no such effect. "So let's say you studied without coffee and decided to drink a cup right before an exam -- that's not going to help you retrieve memories better," says Yassa.
