The study authors wrote that brain infarctions are "a largely preventable brain injury with clearly identified risk factors, and prevention programs."

Study co-author Adam M. Brickman of Columbia University Medical Center in New York said in a news release: "Given that conditions like Alzheimer's disease are defined mainly by memory problems, our results may lead to further insight into what causes symptoms and the development of new interventions for prevention. Since silent strokes and the volume of the hippocampus appeared to be associated with memory loss separately in our study, our results also support stroke prevention as a means for staving off memory problems."
