Not Finishing High School May Lead To Memory Problems

People who don't finish high school are at a higher risk of developing dementia and Alzheimer's disease compared to people with more education, regardless of lifestyle choices and characteristics such as income, occupation, physical activity and smoking, according to a study published in the October 2, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

The study out of Finland followed 1,388 participants through middle-age and late life for an average of 21 years. The participants were divided into three levels: five or less years of education (low), six to eight years (medium) and nine or more years of education (high), the Finnish equivalent of elementary, middle and high school levels.

The study showed that compared with people with a low education level, those with a medium education level had a 40-percent lower risk of developing dementia and those with a high education level had an 80-percent lower risk.
