The research was funded by the National Institute on Aging (NIA), part of the National Institutes of Health, and conducted at the Rush Alzheimer's Disease Center at Rush University Medical Center in Chicago. Julie Schneider, M.D., and colleagues report the findings in the journal Neurology online today.

Among their findings is the observation that the combination of Alzheimer's disease and cerebral infarcts (strokes) is the most common mix of pathologies in the brains of people with dementia. The implication of these findings is that public health efforts to prevent and treat vascular disease could potentially reduce the occurrence of dementia, the researchers say in the paper.

The researchers used data from the Rush Memory and Aging Project
