The effect on Green Tea on memory/brain function

Improvement in Brain Function Seen with Green Tea
Drinking green tea may affect parts of the brain linked to working memory, says the first study ever to use functional neuroimaging methods to test the effects of green tea on the brain.
Magnetic resonance imaging (MRI) showed that tea was associated with increased activation in the prefrontal cortex, a section of the human brain linked to working memory.
The study, published in the European Journal of Clinical Nutrition, adds to the long list of potential health benefits of green tea and its extracts, including reducing the risk of Alzheimer’s, improving cardiovascular and oral health, as well as aiding in weight management.
Green tea contains between 30% and 40% of water-extractable polyphenols, while black tea (green tea that has been oxidized by fermentation) contains between 3% and 10%. Oolong tea is semi-fermented tea and is somewhere between green and black tea. The four primary polyphenols found in fresh tea leaves are epigallocatechin gallate (EGCG), epigallocatechin, epicatechin gallate and epicatechin.
While previous studies have reported potential benefits for green tea on memory, the new study, led by Professor Stefan Borgwardt from the University Hospital Basel in Switzerland, is said to be the first to use functional magnetic resonance imaging to observe changes in the brain following the consumption of green tea extracts.
The researchers recruited 12 healthy volunteers and asked them to perform a working memory task after consuming 250 ml or 500 ml of a whey-based soft drink with or without green tea Extract in a double-blind, controlled repeated measures within-subject trial.
While analysis of the whole brain revealed no significant changes, further analysis showed that consumption of the green tea extract was associated with increased activation in the dorsolateral prefrontal cortex, report Prof. Borgwardt and his co-workers.
In addition, the effects were linked to the doses consumed, with higher doses producing greater activation.
“This is the first neuroimaging study implicating that functional neuroimaging methods provide a means of examining how green tea extract acts on the brain and that green tea extract enhances the engagement of brain regions that mediate working memory processing,” they concluded.

BRAIN POWER with MindMax:

We have some exciting new research to share with you.
Many years of research and clinical studies have shown that people with dementia/Alzheimers have 40% less magnesium in the brain than healthy people. Of course, that is not new information. We have used Magnesium for years, but what we didn’t know was that the magnesium that was available on the market could not cross the blood/brain barrier.

Did you know that between the ages of 20 and 90, the average person loses 5–10% of his/her brain weight—with an accompanying loss in memory, attention and other cognitive functions?  Scientific and medical wisdom suggest that some decline in brain health and cognition is part of the aging process. However, it’s encouraging to learn that neurological structure and function can be preserved as we age. We can now take scientifically steps to preserve—and even enhance—our brain health.


“We are really pleased with the positive results of our studies,” says Dr. Slutsky. “But on the negative side, we’ve also been able to show that today’s over-the-counter magnesium supplements don’t really work. They do not get into the brain.

“We’ve developed a promising new compound which has now taken the first important step towards clinical trials by Prof. Guosong Liu, Director of the Center for Learning and Memory at Tsinghua University,” she says.

Alzheimer’s disease:

An estimated 24 million people worldwide have dementia, the majority of whom are thought to have Alzheimer’s disease. Thus, Alzheimer’s disease represents a major public health concern and has been identified as a research priority.

Learning and memory improved by elevating brain magnesium.

Learning and memory are fundamental brain functions affected by dietary and environmental factors. Here, we show that increasing brain magnesium using a newly developed magnesium compound (magnesium-L-threonate, MgT) leads to the enhancement of learning abilities, working memory, and short- and long-term memory. Our findings suggest that an increase in brain magnesium enhances both short-term synaptic facilitation and long-term potentiation and improves learning and memory functions.

Dr. Guosong Liu, stated in his presentation, that a study he did on mice, might indicate that traumatic memories might gradually lessen with the use of this new form of brain supplement.
