A study published in 2011 suggested that as many as one in two cases of Alzheimer's could potentially be prevented by modifying lifestyle factors. However, this study treated the risk factors as being independent of one another. The researchers estimate that by reducing the relative risk from each of these risk factors by 10 per cent, it will be possible to reduce the prevalence of Alzheimer's in 2050 by 8.5 per cent, preventing 9 million cases." Alzheimer's disease is placing an ever increasing burden on health services worldwide as well as on both patients and their careers.
Our hope is that these estimates will help public health professionals health policy makers design effective strategies to prevent and manage this disease,"
