Caffeine improves memory function in elderly people.
According to lead author Michael Yassa, an associate professor of psychological and brain fields of science at Johns Hopkins University, "We've always known that caffeine has spatial cognition effects, but its specific effects on reinforcing remembrances and making them resilient to trying to forget haven't been examined in humans."
This double-blind study's goal was to provide more light on how coffee and memory interact. "We would have discovered no impact of coffee if we utilized a regular recall and recognition task without these hard identical objects," stated Yassa. However, employing these things forces the brain to do a harder distinction, which we refer to as pattern separation and which appears to be the mechanism that coffee enhances in our example.
