In addition, the number of people diagnosed with mild cognitive impairment with a high risk of dementia has increased rapidly, approaching 3 million.
In the meantime, research has shown that drinking more than three cups of green tea a day helps prevent dementia.
A joint research team, including the Kanazawa University in Japan, said 'Drinking more than three cups of green tea a day can help protect cognitive function in the brain' recently published its findings in the international journal 『Science of Food』.
The research team classified green tea and coffee intake into 0-200ml, 201-400ml, 401-600ml, and 601ml or more of 9000 people aged 65 or older, and conducted a study on cognitive function.
As a result, the higher the green tea intake, the smaller the brain white matter lesion volume, a major indicator of cognitive decline and dementia.
Elderly people who consumed 600ml (about 3 cups) of green tea per day had about 3% smaller volume of brain white matter lesions than those who consumed 200ml or less, and were found to be 6% smaller if they consumed 1,500ml (about 7 to 8 cups) per day. However, no significant association was observed between coffee intake and cerebral white matter lesion size.
The research team said "Drinking more than three cups of green tea a day can help prevent dementia"Green tea is rich in antioxidants, especially catechins such as epigalocatechin gallate (EGCG), which can reduce the risk of cancer and stroke."
However, there is no association between hippocampal volume and total brain volume and green tea intake, which can indicate cognitive decline, so further research is needed, the research team said. In addition, this study was conducted on Japanese people, and it seems necessary to investigate more races.
Meanwhile, as a result of the government's survey of dementia among the elderly aged 65 or older in Korea, the prevalence of dementia among all the elderly in 2023 was 9.25%.
Although it is down 0.25 percentage points from the 2016 survey, more than nine out of 100 people still suffer from dementia.
Due to the aging population, the number of dementia patients is expected to exceed 970,000 this year, surpass 1 million for the first time next year, and reach 2 million 19 years later in 2044.
Memory and language skills have declined significantly in the pre-dementia stage, but mild cognitive impairment that can lead to daily life is also serious.
Compared to 2016, the prevalence of the elderly aged 65 or older surged by more than 6 percentage points to 28.42%.
The number of people diagnosed with mild cognitive impairment this year is expected to reach 2.97 million, surpassing 3 million next year, and exceeding 4 million by 2033.
