More Education Delays Dementia Signs--But Not Damage: Scientific American: "Most of the previous studies describing the link between education and risk for dementia were purely observational—a method in which 'you can't really prove a cause and effect,' says P. Murali Doraiswamy, head of biological psychiatry at Duke University and who was not involved in the new research. He also notes that many of the cognitive tests to diagnose dementia are biased against those who have lower levels of verbal and reasoning abilities due to less education to begin with."
