Coffee Increases Neurological Function

Many people think they cannot function without having their morning coffee, although is there any neurological source to support this? A recent study published in Scientific Reports shows that coffee has positive effects on neurological function, and it does this by rearranging functional brain connectivity.

Caffeine is very popular amongst people who use it to become more alert and awake. Coffee has been linked to many other positive effects on diabetes, Parkinson’s, heart attacks, and cancer prevention. It may also increase. The many neurological function effects of coffee are because it is a stimulant.

The way coffee affects cognition has been disputed, and certain studies claim it can increase executive functioning, reaction time, and memory, while other studies display no change. Although, this research does not look into the relationship between coffee and cognition in more detail.

Hayom Kim and his colleagues used 21 volunteers without neurological or medical conditions. Volunteers were told not to drink caffeine or take any meds for at least 24 hours before the experiment. In addition, volunteers did an EEG and a Mini-Mental State Examination at baseline, then half an hour after the consumption of coffee for comparison.

The study showed that neurological tests were better after coffee consumption.

Increased executive brain function after consuming coffee revealed that there could be a mechanism that triggers the effect of caffeine. It is supported by previous research that used fMRI scans rather than EEG.

Test enhancement validated that coffee can increase neurological function, attention, and working memory.

Even though this study took the proper steps toward figuring out the relationship between caffeine and cognitive functioning, it had some significant drawbacks.

First, the sample size was small and only consisted of educated younger adults, limiting the general population.

Additionally, people react differently to caffeine, and the study did not examine the volunteer’s differences. This can be particularly relevant for regular coffee drinkers versus those who do not drink coffee.
