A current study led by researchers from the National University of Singapore (NUS) revealed that regular tea drinkers have actually much better organised brain areas– and this is connected with healthy cognitive function– compared to non-tea drinkers. The research study group made this discovery after analyzing neuroimaging data of 36 older adults.
” Our outcomes provide the very first evidence of positive contribution of tea drinking to brain structure, and recommend that drinking tea regularly has a protective result against age-related decrease in brain organisation,” described team leader Assistant Teacher Feng Lei, who is from the Department of Psychological Medication at the NUS Yong Bathroom Lin School of Medicine.
The research study was carried out together with collaborators from the University of Essex and University of Cambridge, and the findings were released in clinical journal Aging on 14 June 2019.
Advantages of routine consumption of tea
Past studies have shown that tea intake is advantageous to human health, and the favorable impacts consist of state of mind improvement and cardiovascular disease avoidance. In fact, outcomes of a longitudinal study led by Asst Prof Feng which was published in 2017 showed that everyday consumption of tea can decrease the risk of cognitive decrease in older individuals by 50 per cent.
Following this discovery, Asst Prof Feng and his group even more explored the direct impact of tea on brain networks.
The research group hired 36 grownups aged 60 and above, and collected information about their health, way of life, and mental wellness. The elderly individuals likewise had to undergo neuropsychological tests and magnetic resonance imaging (MRI). The study was performed from 2015 to 2018.
Upon evaluating the individuals’ cognitive efficiency and imaging outcomes, the research study team found that people who took in either green tea, oolong tea, or black tea at least four times a week for about 25 years had brain regions that were adjoined in a more efficient method.
” Take the analogy of roadway traffic as an example– think about brain areas as locations, while the connections between brain regions are roads. When a roadway system is much better organised, the movement of vehicles and travelers is more efficient and uses less resources. Similarly, when the connections in between brain regions are more structured, info processing can be carried out more efficiently,” described Asst Prof Feng.
He included, “We have shown in our previous research studies that tea drinkers had much better cognitive function as compared to non-tea drinkers. Our present outcomes connecting to brain network indirectly support our previous findings by showing that the positive effects of routine tea drinking are the outcome of improved brain organisation caused by preventing disturbance to interregional connections.”
Next action in research study
As cognitive performance and brain organisation are elaborately associated, more research study is needed to much better comprehend how functions like memory emerge from brain circuits, and the possible interventions to better preserve cognition during the aging process. Asst Prof Feng and his team strategy to examine the results of tea along with the bioactive substances in tea can have on cognitive decrease.
