- The causes of dementia are still unknown, and researchers have found a number of factors that can influence a person’s risk of developing the disease.
- Such factors were necessarily accounted for in this study.
- At the study’s conclusion, authors “estimate that, had all participants been continuously married (and shared the same underlying somatic and mental health plus social characteristics of those who marry), 6% of the dementia cases in our study would not have occurred. This is a considerable reduction and is equivalent to the proportion of dementia cases accounted for by smoking and obesity combined, as reported by the Lancet dementia commission in 2020.”
