An Apple a Day...for Alzheimer's?

Doctors are bracing for a huge increase in Alzheimer's patients as baby boomers enter retirement age.

And they're trying to get the word out to forty and fifty year olds that what you eat and what you do now could have a huge impact on how soon you're diagnosed, or whether you even get the disease at all. A new study finds people who drink fruit and vegetable juices three times a week may reduce their risk of Alzheimer's by seventy five percent.

Scientists are still trying to pinpoint what causes Alzheimers, but they do know there's a genetic link. Now they also know the preventive measures for heart disease, like watching your weight, eating healthy, exercising also prevent or delay the onset of Alzheimer's. William Thies, with the Alzheimer's Association says, "We do know that if you adopt these risk factors, you as an individual will stay as functional as you can for as long as you can."

A new computer program could help doctors determine if you're at risk for Alzheimer's. The program is a PET scan that researchers developed as a method of measuring metabolic activity in a small area of the brain called the hippocampus.

Researcher say low metabolism levels in the hippocampus increase a person's risk for Alzheimer's disease.
