I'm a big fan of coffee, and even when I'm busy, I try to find free time to drink it.
Savoring a fragrant coffee with crema is truly a blissful moment.
Life without coffee is as hard to imagine as sushi without wasabi, bread without butter, and spring without cherry blossoms.

I was interested in how much coffee people around me drink, and I wanted to know the relationship between lifestyle habits and cerebral infarction.
It is said that many Japanese people have a habit of drinking coffee, but according to the results of a questionnaire survey of 314 people (242 people under the age of 65) who underwent a brain checkup, 75% said that they drink more than one cup of coffee a day. , and 26% of them drank 5 or more cups.
Regarding tea, 84% of respondents drank 1 or more cups of tea a day, and 18% drank 3 or more cups.
My family lives in Shizuoka, so I use tea instead of water. At home, I have a habit of drinking tea while eating, and drinking coffee after meals or during breaks.
For me, coffee and tea are both essential drinks in my life.

In a survey, 26% of those who underwent a brain checkup had a cerebral infarction without even knowing it (generally called a hidden cerebral infarction), but those who drank 3 or more cups of coffee every day. It was found that there were few hidden cerebral infarctions. No such relationship was observed with tea, but in defense of tea, there may be no significant difference due to the large number of Japanese who drink tea.
Until now, there have been reports that people who drink a lot of coffee have fewer cerebral hemorrhages and strokes, but I think this is the first time in the world that it has been proven that people who have a habit of drinking a lot of coffee have less hidden cerebral infarctions.
On the other hand, it is already known that people with hidden cerebral infarction are more likely to develop dementia such as Alzheimer's disease. In an aging society like Japan, it is necessary for society as a whole to acquire lifestyle habits that prevent Alzheimer's disease.

In 2016, I published an English paper on my presentations at the General Assembly of Brain Surgery, Stroke Society, Brain Dock Society, etc. in the medical journal Journal of Stroke and Cerebrovascular Disease.
