Scientists still investigate why some people develop Alzheimer’s disease and others don’t, but certain factors increase the risk, according to National Institutes of Health (NIH). The causes of Alzheimer’s disease is not fully understood, but several factors that affect each person differently.
- Age is the greatest known risk factor for Alzheimer’s disease. Most individuals with the disease are 65 and older.
- Family history is the strong risk factor as Alzheimer’s disease tends to run in families. The risk increases if more than one family member has the Alzheimer’s disease.
