Researchers add, even one extra year of education can significantly cut the risk of developing the brain wasting disease.
These findings could have important implications for public health at a time when populations in many countries are rapidly aging and dementia numbers are expected to rise sharply.
Scientists determined that more education is not associated with any differences in the damage to the brain, but people with higher education can cope with that damage better.
The study in the journal "Brain" also found, for every extra year of education, there was an 11 percent decrease in the risk of developing dementia.
