Causes and Risk Factors for Alzheimer’s disease

No one is sure what causes Alzheimer’s disease. Some researchers believe a protein imbalance or a virus could be the cause. Environmental and genetic factors could also be a possible cause. Age, a family history of Alzheimer’s disease, and head injury are the most common risk factors for Alzheimer’ disease. Some studies have shown that more women than men have Alzheimer’s disease.  Other studies have also shown that education may be a factor in developing Alzheimer’s disease: those who are highly educated may be less likely to develop Alzheimer’s disease.  There is conflicting evidence of metals, such as aluminum, possibly causing Alzheimer’s disease.
