One in ten Americans who are 65 and older suffer from Alzheimer’s dementia. It’s the 6th leading cause of death in the country, and it is a scourge worldwide. But little is known about what causes Alzheimer’s, and cures have been elusive. Dr. Verna Porter specializes in treating people with Alzheimer’s, and she remains optimistic. Until we have a remedy, she advises people to eat well and get plenty of sleep. Patients with Alzheimer’s often have abnormal levels of a gummy plaque called amyloid protein crowded around the neurons of the brain. No one knows for sure what causes it to accumulate. What we know for sure is that sleep clears toxins from the brain, amyloid protein among them. Yet so few of us get enough of it. Eating a diet that’s low in sugar, and intermittent fasting, also may clear toxins. Even when we do invent a cure for Alzheimer’s, prevention will still be the best medicine, Dr. Porter says. Listen now for more on the mysterious origins of Alzheimer’s and what you can do to live with it if it strikes you or a relative.
