Study: College Education Helps Fight Dementia
(London) -- A college education may be the best defense against dementia. A new study out of Britain and Finland found a strong link between higher education and a person's ability to weather changes in the aging brain. For every year of education past high school, a person's risk of dementia decreased eleven-percent. A four-year-college degree meant a 44-percent decline in the risk of getting Alzheimer's disease. Scientists dissected the brains of both people who'd gotten college educations and people who hadn't. Both showed signs of brain wasting. But the people who'd had higher levels of education had shown fewer signs of Alzheimer's disease while alive. Researchers say that's because an educated person's brain is more nimble, allowing him or her to think through problems or overcome symptoms of the disease. Roughly 35-million people around the world have Alzheimer's, which is marked by a decline in brain function. The numbers are expected to rise as the world's population ages. The findings are published in the journal "Brain." |
