In 2003 Terry Wahls, M.D., was diagnosed with secondary progressive multiple sclerosis and soon became dependent upon a tilt-recline wheelchair. She now uses intensive directed nutrition in her primary care and traumatic brain injury clinics. Dr. Wahls is the lead scientist in a clinical trial testing her protocol in others with progressive MS. Watch this video for her personal story. Ignore the warning. The warning by the TEDx event folks illustrates to me that the organization is a little to conventional. Being conventional means that we keep on doing what we've been doing. That doesn't work when it comes to curing chronic diseases.
