。, ,The main risk factors for the disease are a lack of exercise, smoking, depression and poor education, it says., ,Previous research from 2011 put the estimate at one in two cases, but this new study takes into account overlapping ¹ risk factors., ,Alzheimer's Research UK said age was still the biggest risk factor., ,Writing in The Lancet Neurology, the Cambridge team analysed population-based data to work out the main seven risk factors for Alzheimer's disease., ,These are: , Diabetes, Mid-life hypertension, Mid-life obesity², Physical inactivity, Depression, Smoking, Low educational attainment³, ,They worked out that a third of Alzheimer's cases could be linked to lifestyle factors that could be modified, such as lack of exercise and smoking. , ,The researchers then looked at how reducing these factors could affect the number of future Alzheimer's cases., ,They found that by reducing each risk factor by 10%, nearly nine million cases of the disease could be prevented by 2050., ,In the UK, a 10% reduction in risk factors would reduce cases by 8.8%, or 200,000, by 2050, they calculated., ,Current estimates suggest that more than 106 million people worldwide will be living with Alzheimer's by 2050 - more than three times the number affected ⁴ in 2010.
