Green Tea Extract Boosts Cognitive Performance

Green tea and it’s extracts have many health improving benefits including reducing the risk of developing certain health conditions, such as cancer, heart disease and type 2 diabetes. Previous studies have indicated that green tea can be beneficial to our brain’s cognitive functions as well.

A recent study published in the journal Psychopharmacology set out to determine if green tea extracts enhanced and/or improved brain connectivity during working memory processing and whether the connections between the neuronal structures were related to task performance.

The study involved 12 healthy male volunteers with an average of 24 years and participants were given drinks, some with green tea extract and some without. The volunteers did not know which they had been given.

Brain activity was then monitored via magnetic resonance imaging (MRI) while they carried out a series of tasks involving the memory.

The study concluded that those who had been given the drink with green tea showed increased connectivity between various parts of the brain including the frontal cortex of the brain. This connectivity was linked to an improved performance on the working memory tasks.

The researchers said: “The present study shows that green tea extract enhances functional connectivity from the parietal to the frontal cortex during working memory processing in healthy controls.

“Interestingly, this effect on effective connectivity was related to the green tea induced improvement in cognitive performance.” Basically stating that if it were not for the green tea, this exciting positive brain boosting memory result would not have happened!

The researchers have recommended further study into how green tea can help with cognitive impairments such as dementia. There are also great potential improvements in people with short term memory problems as well.
