One in three cases of Alzheimer’s worldwide potentially preventable, new estimate suggests
A third of Alzheimer’s disease cases worldwide can be attributed to risk factors that can be potentially modified, such as lack of education and physical inactivity, according to NIHR-funded research published in The Lancet Neurology this week.
The estimate is lower than the previous estimate of one in two cases as it takes into account the fact some of the risk factors used in previous studies are related. For example, three of the risk factors (diabetes, hypertension and obesity) are linked with physical inactivity and all of these are related to educational level.
Professor Brayne adds: “Although there is no single way to prevent dementia, we may be able to take steps to reduce our risk of developing dementia at older ages. We know what many of these factors are, and that they are often linked. Simply tackling physical inactivity, for example, will reduce levels of obesity, hypertension and diabetes, and prevent some people from developing dementia as well as allowing a healthier old age in general – it’s a win-win situation.”
