New WHO guidelines released on 14 May 2019 advocate physical activity and a healthy lifestyle as important strategies to prevent dementia. “Unfortunately, many people with dementia are diagnosed too late, and treatment options are then less effective. Since dementia remains a condition without a cure, early detection, treatment, care and support are key in terms of an effective public health response. Risk reduction strategies, such as pursuing a healthy lifestyle through regular exercise and by not smoking, are also very important,” comments Bente Mikkelsen, Director of the Division of Noncommunicable Diseases and Promoting Health through the Life-course, WHO/Europe.
