Study finds people who are active and eat well have fewer brain effects linked to the disease.

A healthy diet and regular exercise might be the keys to keeping your brain free of changes that lead to Alzheimer's disease, a small study suggests.
Researchers studied 44 patients between the ages of 40 and 85 who had mild memory problems. The investigators found that the brains of those who followed a Mediterranean diet and were physically active had fewer plaques and tangles, a hallmark of Alzheimer's, than those whose diet was less healthy and who were less active.
"Alzheimer's disease is known to be incurable, but it was not thought until recently that it can be preventable," said lead researcher Dr. David Merrill. He is an assistant clinical professor of psychiatry and biobehavioral sciences at UCLA David Geffen School of Medicine in Los Angeles.
“已经知道，阿尔茨海默症不可治愈的，但最近发现它可以防御。”这是首席研究员David Merrill博士所说。他是洛杉矶加州大学洛杉矶分校David Geffen医学院精神病学和生物行为科学助理临床教授。
Numerous studies have suggested that a healthy lifestyle is related to reduced brain shrinkage and lower rates of brain tissue atrophy, he said.
But this is the first study to show how lifestyle factors directly influence levels of abnormal protein deposits in the brain that have been long tied to Alzheimer's disease. Plus, the study subjects were people with subtle memory loss who had not yet been diagnosed with dementia, Merrill noted.
