By the year 2020, America will have 14 million people in need of full-time care for Alzheimer's disease.
Anxiety disorders currently are the most common mental illness in the United States, affecting 40 million adults. Millions suffer from "brain fog," a term that is only recently getting attention.
What do these alarming statistics have in common? According to leading functional physician, Dr. Mark Hyman, they can be triggered by poor brain health.
Hyman admits he once suffered from chronic fatigue syndrome and felt like he had dementia, depression, and ADD — all at the same time.
"My brain felt broken," he says. "Although I wouldn't wish this on anyone, I truly believe the experience taught me how to be a better physician and it led me to the world of functional medicine. I finally understand that what we do to our bodies, we do to our brains."
