Dr. Alan MacDonald, U.S. pathologist is a medical detective, having investigated Lyme Borrelia for nearly 40 years. He was the first to prove maternal transmission of Lyme and was amazed to find that 7 out of 10 alzheimer's brains he tested revealed the live Borrelia spirochete. His groundbreaking work shows that, in some cases, alzheimers is treatable and can be cured.
