Bad to know: Alzheimer's disease progresses faster in highly educated
TOLEDO, Ohio -- According to a recent study, Alzheimer's disease advances more quickly in highly educated people. But before you quit school and abandon your college education, studies also show that the more years of higher education, the later the disease may appear.
Alzheimer's disease is a form of dementia that affects the brain mostly in areas of thought, memory and language. Dr. Nikolaos Scarmeas of Colombia University Medical Center in New York, studied 312 people diagnosed with Alzheimer's, with different levels of education, for five years, testing their brain functions. His results concluded that all patients showed a decline of 9 percent overall, but each additional year of education saw a 0.3 percent additional deterioration.
The theory of "cognitive reserve" explains his findings. It states that people with higher brain skills and functions are able to delay illness, because of more brain cells or more efficient brain systems. However, as the diseases accumulate in the brain, the brain eventually succumbs to the diseases, which quickly take over, and progress faster than normal.
Scientists do not know what causes the disease or how to cure it. About 12 million people throughout the world currently suffer from Alzheimer's disease.
