A healthy lifestyle can help reduce the risk of Alzheimer’s disease and other dementias. It has been estimated that up to half the cases of Alzheimer’s disease worldwide may be the result of seven key modifiable risk factors: diabetes, high blood pressure, obesity, smoking, depression, cognitive inactivity or low education, and physical inactivity. Risk factors are characteristics of the person, lifestyle, environment, and genetic background that contribute to the likelihood of getting a disease. Risk factors on their own are not causes of a disease. Risk factors represent an increased chance, but not a certainty, that Alzheimer’s disease will develop. Some of the risk factors for Alzheimer’s are the same as for cardiovascular disease. By leading a healthy lifestyle and taking regular exercise you will be helping to keep your heart healthy. It’s possible you will be lowering your risk of Alzheimer’s too. Some people develop mild memory problems that are worse than those to be expected at their age, but that isn’t yet interfering with normal daily activities.
