Preventing Alzheimer's: Study Shows Diet and Exercise Are Effective
Dr. Miia Kivipelto from the Karolinska Institute in Sweden knew that several studies have linked some lifestyle behaviors, such as exercise and a healthy diet, as well as being more socially active, to less cognitive decline and stronger scores on memory and organizational tests. But it wasn’t clear whether people who ate better, exercised more and had more friends also shared something else in common that could explain their ability to slow down dementia symptoms.
So Kivipelto conducted one of the first studies to randomly assign 1,260 older individuals at high risk of developing Alzheimer’s to a lifestyle intervention or to normal health care, to see if the behaviors linked to better brain health actually helped to stave off intellectual decline. “We were surprised that were able to see a clear difference already after two years,”
