A group of friends from around the world have gathered because they all have something in common. They all want to have fun. They all want to exercise. And they all want to eat healthy. Those reasons are great. But they are not why these people have banded together. The have banded together because they all carry the APoE4 gene. That gene increases their risk of getting the brain-destroying disease known as Alzheimer’s. We all found out that we carry one or two copies of the APoE4 gene. Which is it puts us at higher risk for Alzheimer's. Susan, who gives only her first name, says her father died from Alzheimer's. As the disease progressed in his brain, doctors had little to offer except a memory-boosting drug called Aricept. She adds that doctors had a fatalistic attitude, meaning they acted as if they could do nothing to reverse the damage from Alzheimer’s.
