Two prominent California doctors, with bestselling books, insist we have the power to heal our own brains from diseases. They say it should start when we're young and begin with a look at the way we eat. Two women we spoke with who followed that advice say ... they reversed their early symptoms of Alzheimer's disease by making food and lifestyle changes based on research by neuroscientist Dr. Dale Bredesen. He wrote a book called The End of Alzheimer's." "Two years ago, I scored mildly cognitively impaired on a cognitive assessment test," said Dr. Sally Weinrich. "Most recently, I scored perfect!" Weinrich, a former cancer researcher and grandmother, followed the Bredesen protocol for several months and is able to cook once again for her large family, pick up the grandkids from school and she's learning Spanish. Deborah, a very active mother of four and a lawyer, says, "Over a period of four to six months, the symptoms I was experiencing all reversed and I returned to my cognitive functioning that had been my norm when I was younger." She was able to recover her ability to sight-read notes when she plays the piano. Adda, an active 51-year-old grandmother, [said] that she improved her ability to think clearly and she lost almost 80 pounds after making dramatic food and lifestyle changes ... after she started working for cardiologist Dr. Steven Gundry nearly six years ago. He wrote a book called "The Plant Paradox."
