Risk Factors for Alzheimer’s (2011)

This study investigated risk factors for Alzheimer’s. This study looked at the evidence regarding seven modifiable risk factors for Alzheimer’s. They calculated that about half of the 33 million cases worldwide could be prevented (that’s 17 million) and calculated that if these risk factors were to be modified to only a ‘relatively modest degree’, specifically by 10-25% as many as 1 – 3 million cases of the current 33 million worldwide could have been prevented.

The risk factors they considered were diabetes, midlife high blood pressure (hypertension), midlife obesity, smoking, depression, cognitive inactivity or low educational attainment, and physical inactivity. A major shortcoming of this report is that they didn’t consider dietary and lifestyle factors such as increasing B vitamins / reducing homocysteine, increasing essential fats and vitamin D, adopting a Mediterranean diet.
