"...In a study of more than 1,400 Finnish adults followed for two decades, researchers found that the more years of education participants had, the lower their risk of developing dementia, including Alzheimer's disease...with fewer than five years of education, those with six to eight years were 43 percent less likely to develop dementia. Men and women with nine or more years of schooling had an 84-percent lower risk of dementia...can be seen as support for the "brain reserve" hypothesis on dementia risk...According to this theory, older adults with more education or higher IQs are able to withstand more Alzheimer-linked brain damage before showing symptoms...A key question, according to Ngandu, is whether education can actually generate a greater brain reserve -- or whether people with an innately greater reserve go further in their education."

The last question is indeed key. Although they might not be mutually exclusive.

Does education help with vascular dementia? The etiology seems more related to genes, diet and exercise. If it does include vascular dementia why not give a simple % in relation to other dementias. And list the other dementias that might be helped by education. The problem is there are dozens of forms of dementia, most appear not connected to education at all. I only mention this because articles on dementia almost never mention which forms of dementia they are talking about. It's as if all the journalists writing about dementia have a new form of dementia... whose name will not be mentioned.
