What is "dementia"?"Dementia" that anyone may develop onset. As the aging progresses, it is becoming one of the diseases that gather attention year after year.
Two types of "dementia"
- Alzheimer's disease
- Vascular dementia
It is said that "Alzheimer's disease" occurs because the nature and properties of brain cells change, but the real cause is still not well understood, and research on its mechanism is under way. "Vascular dementia" is caused by diseases associated with blood vessels of the brain and the brain, such as cerebral infarction, stroke, cerebral hemorrhage.
"Theanine" and "Caffeine"There are currently no drugs or cures effective for "dementia" itself. Therefore, in order not to become "dementia", it is generally considered important to live healthily such as meals and exercise.
TheanineThe ingredient "theanine" occupying more than half of the amino acids of green tea.
A test was conducted to evaluate the symptomatic change of dementia by ingesting about 47.5 mg daily capsules made from powdered green tea rich in theanine for one year. In this examination for people over 60 years old, we asked the subject to answer simple questions and evaluated the extent of dementia based on their correct answers. As a result, it was possible to confirm a significant difference in the average value of the score in the group not taking the capsule of green tea spatula and not grouping.
CaffeineCaffeine is a versatile substance that improves various cognitive functions including memory. Although ingestion in large quantities may be dangerous, it is always necessary to treat it cautiously, but there is almost no doubt that there is an effect of improving memory.
Researchers at John Hopkins University conducted experiments on people who normally do not consume caffeine. After seeing the series of images, the subject was given 200 mg of caffeine tablet or placebo that looked the same. On the next day, each group showed exactly the same images, similar images, completely different images as the previous day, The group who ingested caffeine the day before recognized the image similar to the original image with a significantly high probability compared with the group who drank the placebo, and was able to distinguish the difference in the details. In other words, the group who ingested caffeine remembered concrete differences between very similar images, strongly indicating that they are demonstrating sharp memory power.

There is also a report that intake of caffeine at the same time as theanine as compared with ingesting each one independently, there is a report that improvement of concentration ability and memory ability is recognized and synergistic effect can be expected.
"People who drink 2 cups of green tea or more a day are less likely to become cognitive impairment than people who drink 3 cups a week" Originally, the decline of memory power has been thought to be a major cause of brain nerve cells being hurt by active oxygen. Catechin contained in green tea has the function of suppressing the action of active oxygen and preventing the nerve cell from being damaged. The amount of caffeine is also worrisome, but let's prevent dementia by continuing to drink the appropriate amount of tea.
