Here may be why you...uh... run short of "storage space"Education shrinks brain timesofindia.com DETROIT:First the bad news: Older people with lots of education show more brain shrinkage than those who spent less time hitting the books. The good news is higher education levels give the elderly more protection from dementia and memory loss, according to a medical study released Monday. ''Our brain cells are dying, but if we have educated ourselves, that provides a buffering effect such that our functioning remains intact,'' said Dr Edward Coffey, chair of the Henry Ford Health System Department of Psychiatry and principal investigator for the study. The research, published in the July issue of the journal Neurology, examined 320 healthy men and women from 66-90 years old. Using magnetic resonance imaging, researchers measured brain size by tracking cerebrospinal fluid surrounding the outside of the brain. The study found that elderly people with 16 years of education had 8-10 per cent more fluid around their brains than did those who had only gone to school for four years. Dr Coffey was quick to point out the study did not conclude that lots of education causes smaller brains. In fact, he said everyone's brain starts shrinking beginning at young adulthood. On average, a person's brain will shrink 2.5 per cent every 10 years. Dr Coffey likened the effect of a high amount of schooling on the brain to exercising a muscle to keep it in shape. ''Everybody has some shrinkage. We're able to tolerate it to different extents. If you have more education, the shrinkage causes less problems for you than those with less education,'' he said. Dr Coffey is the same researcher who published a study in February 1998 that found men's brains shrink faster with age than women's. (Reuters)
