Age, sex, genetics, and ethnicity shape your Alzheimer's risk in ways you can't change. Risk roughly doubles every five years after 65, and by 85 about one-third of people develop it. Inheriting the APOE4 gene from either parent markedly raises your odds.

There are 4 risk factors that are called non-modifiable. You can't change them. It's age, gender, ethnicity or race, and genetics. Women, to date, develop Alzheimer's more than men. Your age determines your risk factor. Starting at the age of 65, and then it doubles like every 5 years. So your risk is higher at 70, and then 75. By the time any of us are 85 years old, 1 in 3 of us will develop Alzheimer's disease. And then there's genetics. There is a gene, a genetic gene called the APOE4 gene, and it can be passed down directly from either our mother our father, or both of them. That will increase our risk. So you've got the non-modifiable ones off the bat. If all 4 of those apply to any one individual, they're at a significantly higher risk than somebody that none of those apply to. Then we have the modifiable risk factors. Those are lifestyle choices, diet, getting proper exercise, underlying health conditions that
