(CNN) Your relationship status might be associated with your dementia risk, and a new research review paper reveals how. Yet the relationship between marriage and dementia risk is not causal: "We don't think that it is marriage itself or wearing a wedding ring which reduces people's risk of dementia," he said. In other words, although the study found an association between being married and reduced risk of dementia, the findings can't prove that marriage directly decreases dementia risk. "At the end of that study, we should be able to say some much more strong things about the effect of modifiable risk factors and dementia risk," he said. "Hence, although potentially modifiable risk factors for dementia exist, this does not mean that dementia is easily preventable."
