The Whole Story with Anderson Cooper S02E13 - The Last Alzheimer's Patient

CNN Chief Medical Correspondent Dr. Sanjay Gupta takes a groundbreaking look at the latest medical research showing that symptoms of Alzheimer's disease can be prevented, slowed, and potentially even reversed. 

In a report spanning five years, Dr. Gupta follows Alzheimer's patients through their courses of treatment and explains why so many experts are calling it the "most hopeful" era for dementia patients and their loved ones. A practicing neurosurgeon, Dr. Gupta also evaluates the pros and cons of the latest tests designed to measure an individual's risk for the disease. He even undergoes the battery of tests himself, weighing his own risk for the world's most common neurodegenerative disorder.

"Preventing problems down the road is health care, instead of sick care," said Dr. Gupta. "Today, getting off the road to Alzheimer's disease and other dementias is so much simpler than we previously thought. The decisions we make every day – to eat healthy, to move more, to learn new skills, and to spend time with loved ones – sounds easy, but the evidence is clear. It can, and it will, lead to better brain health."

Today, nearly 7 million Americans are living with Alzheimer's disease. In "The Last Alzheimer's Patient," Dr. Gupta also details what viewers can do in their everyday lives that could help drive down their own risk for developing the devastating disease.
