The risk factors for AD include modifiable risk factors and non-modifiable risk factors.
Non-modifiable risk factors include:
Age: The older you are, the greater your risk of developing AD. After age 65, your chance of developing Alzheimer's doubles every 5 years. People who are 85 years of age or older have a nearly 50% chance of having the disease.
Genetics and family history: You are more likely to get AD if you have a family history of AD, meaning that one or more of your parents, siblings, or children has the disease. Scientists also think that certain genes in your DNA may increase your risk for AD.
Modifiable risk factors are as follows:
Environmental/lifestyle factors: It is likely that your environment and your lifestyle habits also affect your risk for AD. A history of head trauma, cardiovascular or heart problems, diabetes, and obesity appear to increase your risk for AD. To help prevent these health problems, wear a helmet when riding a bicycle, always buckle your seat belt when in the car, establish a regular exercise routine, eat right, and avoid tobacco products.
Concomitant diseases: Cardiovascular or heart problems, hypertension, hyperlipidemia, and anemia appear to increase the risk for AD. Prevention and treatment of these diseases would reduce the risk of AD.
