Risk Factors for Alzheimer's Dementia: What You Need to Know
Deep Dive Podcast: What Are the Alzheimer's Risk Factors?
Alzheimer's dementia is a complex disease that is thought to be caused by a combination of genetic, lifestyle, and environmental factors. While some risk factors for Alzheimer's dementia cannot be changed, such as age and genetics, several modifiable risk factors can be addressed to reduce the risk of developing the disease.
Non-Modifiable Risk Factors
Age
The most significant risk factor for Alzheimer's dementia is increasing age. The risk of developing Alzheimer's dementia doubles every five years after age 65. However, it is essential to note that Alzheimer's dementia is not a normal part of aging.
Genetics
Another risk factor for Alzheimer's dementia is genetics. The most well-known genetic risk factor is the APOE gene. The APOE gene has three forms: e2, e3, and e4. The e4 form of the APOE gene increases the risk of developing Alzheimer's dementia.
Family History
Having a family history of Alzheimer's dementia also increases the risk of developing the disease. Individuals who have a parent or sibling with Alzheimer's dementia are more likely to develop the disease themselves.
Modifiable Risk Factors
Cardiovascular Health
Maintaining good cardiovascular health is important for brain health. Cardiovascular risk factors, such as high blood pressure, high cholesterol, and diabetes, can increase the risk of developing Alzheimer's dementia.
Physical Activity
Regular physical activity can help reduce the risk of developing Alzheimer's dementia.
Diet
Eating a healthy diet can also help reduce the risk of developing Alzheimer's dementia.
Education
Higher levels of education have been linked to a reduced risk of developing Alzheimer's dementia.
Social and Cognitive Engagement
Staying socially and cognitively active throughout life may help reduce the risk of developing Alzheimer's dementia.
Other Risk Factors
Other potential risk factors for Alzheimer's dementia include:
Traumatic brain injury (TBI)
Sleep disorders
Air pollution
Critical illness
Reducing Your Risk
While you cannot change some risk factors for Alzheimer's dementia, such as your age and genetics, you can take steps to reduce your risk by addressing modifiable risk factors. This may include:
Maintaining a healthy lifestyle
Getting regular physical activity
Eating a healthy diet
Staying socially and cognitively active
Protecting your brain from injury
