- Alzheimer's disease (AD), in most cases, is not hereditary.
- You can decrease the risk of having AD by maintaining healthy weight and regular physical activity.
- There is insufficient evidence about the effectiveness of different nutrients, foods, diets or supplements in the prevention of AD.
According to Alzheimer's Society Canada, modifiable risk factors for AD include:
diabetes, high blood pressure, obesity, smoking, depression, cognitive
inactivity or low education, and physical inactivity.
Other risk factors can include: excessive alcohol drinking, high blood cholesterol levels, stroke and repeated head injuries.
Alzheimer disease and genetics:
Most Alzheimer’s disease does not run in families and is described as
“sporadic”. Rare cases of Alzheimer’s disease are inherited or
Diet. Various systematic reviews, like this one, mention the association (but not necessary the cause-effect relationship) between Mediterranean diet and lower risk of AD.
Cochrane has a long list of study reviews about the preventative effect of supplements, herbs and alternative treatments on AD; in most cases, there is no evidence of their effectiveness.
