Dementia rates are declining in Europe and the United States thanks to a shift to healthier lifestyles, according to a new study.
According to a study conducted by the Harvard School of Public Health with more than 60,000 people, the risk of developing dementia has decreased by 15% per decade over the last 30 years.
The researchers who conducted the study, which was presented Wednesday at the Alzheimer's Research UK conference in Harrogate, England, explained that the drop could be due to the drop in the rate of smokers, the figures being at their lowest in England. 2017.

Lead author, Albert Hofman, chair of the epidemiology department at the Harvard School of Public Health, said, "Over three decades, the incidence rate of dementia in Europe and North America North seems to decrease by about 15% per decade.
"This discovery is more pronounced in men than in women and will likely depend on changes in cardiovascular risk factors and lifestyle.
"We know that smoking rates among men have dropped dramatically in recent decades. Although many people may have persuaded to quit because of an increased risk of cancer or heart disease, it is also a key risk factor for dementia. . "
According to government figures, the number of smokers in England in 2017 was about 6.1 million, or 1.6 million less than in 2011.
Hofman added that the decline may not continue, however, because of the increased risk of dementia, such as obesity and diabetes.
Dementia is a condition that affects the brain and is more common in people over 65 years of age.
According to the NHS, this is a syndrome badociated with a continuing decline in brain function that can lead to memory loss, decreased movement, and difficulty performing daily activities.
Dr. Carol Routledge, Director of the Alzheimer's & Research UK Association, commented on the study: "While there is no medication to slow down or stop diseases such as Alzheimer's disease, there is strong evidence that what is good for the heart is good for the brain. .
"In addition to maintaining healthy blood pressure, the best current evidence suggests that not smoking, drinking only within the recommended limits, staying mentallyphysically active, a balanced diet and cholesterol control can all contribute to the health of our brains as we get older. "
Although the preliminary findings of the study were presented at the conference, the full report is expected to be released later this year.
