Lots of people claim they can’t function without their morning coffee, but is there a neurological basis for that? A study was published in Scientific Reports He suggests that coffee has beneficial effects on cognitive function, and may do so by reorganizing the brain’s functional connectivity.
Coffee is a very popular drink that people use to be more alert and alert. It has been linked to other positive outcomes, such as preventing cancer, diabetes, Parkinson’s disease, and heart attacks. It can also increase. Many of the effects of coffee are due to it being a stimulant.
The role of coffee in cognition has been discussed, with some studies reporting that it can improve reaction time, memory, and executive performance, which other studies have shown no change. This research seeks to further explore the relationship between cognition and coffee.
Hayom Kim and colleagues used 21 participants without medical or neurological conditions. Participants were instructed not to drink any caffeinated beverages or take any medications for 24 hours prior to the experiment. Participants completed a mini mental state test and EEG at baseline and then 30 minutes after drinking canned coffee for comparison.
The results showed an improvement in the neurological examinations after drinking coffee. The improved executive function after drinking coffee suggests that there may be a mechanism underlying the effect of coffee, which is supported by previous research that used fMRI instead of EEG. The improvement in the tests supported the ideas that caffeine could increase attention, working memory, and cognition.
Although this study took positive steps to understand the relationship between cognitive performance and caffeine, it also had some important limitations. First, the sample was small and consisted of highly educated youth, which makes generalizability to the general population limited. In addition, all individuals react to caffeine differently, and this study did not take into account individual differences. This may be especially appropriate for regular coffee drinkers versus people who don’t drink coffee at all.
