In 2011, researchers at Zhejiang University School of Medicine in Hangzhou, China, followed up about 12,000 people over the age of 45 and without dementia.
The researchers regularly checked how much time they spent surfing the Internet and whether there were signs of dementia.
2.2% of people who surfed the Internet steadily for about 10 years developed symptoms of dementia, while 5.3% of those who did not developed dementia.
In addition, smartphone users were less likely to have dementia than computers. The researchers explained that this is because they use smartphones more often than computers.
Researchers "Internet use has the potential to slow cognitive decline associated with aging. Can improve attention and mental motor skills and improve cognitive reserve"The sense of belonging created through online activities also seems to play a role in slowing dementia." However, it seems that additional research on Internet surfing hours per day should be conducted.
The findings were published in the international journal 『JMIR』.
Meanwhile, researchers at New York University's School of Global Public Health have obtained similar findings.
The researchers followed up with about 20,000 people aged 50 to 65 who had no dementia over 17 years.
As a result, within two hours a day, internet users had only a 1.54% risk of developing dementia, while those who did not use the internet were much higher at 10.45%. It was also found that the average Internet user was half as likely to suffer from dementia as those who did not go online.
The findings were published in the journal 『The Journal of the American Geriatrics Society』.
