Xinhua published an article Swedish researchers reported in the online edition of the British journal “Brain” that if a man has poor cognitive ability as well as cardiovascular health at a young age, he will be more likely than the average person to develop dementia, or early-onset dementia, before the age of 60. Researchers at Sweden’s Gothenburg University analyzed data on more than 1.1 million men in Sweden. The men were tested for cognitive ability and cardiovascular health at age 18 and were then followed for an average of 26 years. The researchers found that if a man had poor cardiovascular health at a young age, he was 2.5 times more likely to develop early-onset dementia; if he had poor cognitive ability, he was four times more likely to develop early-onset dementia. When both conditions are present, he is 7 times more likely to develop early-onset dementia than the average person. People with early onset dementia are usually not yet retired and still have the responsibility of raising their minor children. Therefore, the impact of early onset dementia on both the person and the family is significant. Researchers say that physical and mental exercise can help prevent and treat dementia by enhancing physical as well as mental function.
