It is estimated that 45 million people worldwide are suffering from dementia, and it costs about $ 818 million to treat dementia and nursing care.
The number of patients with dementia continues to increase, and it is estimated that by 2040, 1.2 million people may be suffering from dementia. This is a 57 percent increase from 2016.
"There are many ways for individuals and health authorities to prevent dementia," said Jill Livingston, a professor of psychiatry at the University of London.
While experts can not be certain of what is the most effective way to prevent dementia, Livingston emphasized that he should follow advice on the many ways that experts can help mental health.
Professor Cleve Ballard of Exeter University, co-author of the report, said, "Livingston's research needs people to develop the right dietary habits, maintain proper weight, and periodically check blood pressure."
Nicolas Davis, a host in the Guardian's weekly science department, said: "The survey found that 35 percent of the theoretically preventable dementia was not prevented by factors such as loss of middle-aged hearing, expulsion before middle school, and smoking. Social isolation, diabetes, hypertension, obesity and lack of exercise also potentially contributed to the onset of dementia. "
"If we find a solution to the major genetic risk factors for dementia, we can reduce the incidence of dementia by 7 percent," Davis added.
