Risk Factors

Most of my research up to this point has been from websites dedicated to the research and informational websites for Alzheimer’s. Along with using the Auraria library database and research options. For this particular question I used the alzheimer's disease website as well as finding a peer reviewed newspaper article on preventing and reducing the risk of alzheimer's.
Today's question was aimed at finding who is at risk and what other factors can there be.
There are three major risk factors that will never change; family history, heredity, and age. Another risk factor for Alzheimer’s disease is head trauma; especially when or if a person loses consciousness or the trauma occurs repeatedly. From this could it mean that those that constantly participate in full contact sports may be putting themselves at more risk in their older ages for the disease?
Another risk factor links a person’s heart health with brain health, meaning that many heart conditions such as
high blood pressure, heart disease, stroke, diabetes and high cholesterol can increase the risk of developing Alzheimer’s. Latinos and African-Americans are at greater risk for developing Alzheimer’s due to the historical fact of higher rates of such vascular diseases.
