Michael A. Williams, M.D., FAAN, the medical director of The Sandra and Malcolm Berman Brain & Spine Institute, is a leading authority on the brain, its different levels of consciousness and disorders. The stages of disorders include wakefulness, awareness, consciousness, coma, vegetative state, minimally conscious state, and brain death.

With questions about Whitney Houston and Bobby Brown’s daughter, Bobbi Kristina, after she was found unconscious in a bathtub, these terms, what they mean and the questions associated with them are the theme of discussions across the country. Dr. Williams is able to share information and offer insight on this subject.

Dr. Williams is a graduate of the Indiana University School of Medicine. Following an internship at Methodist Hospital of Indianapolis, he completed a neurology residency at Indiana University Medical Center. His postdoctoral education continued with a two-year fellowship in neurosciences critical care at Johns Hopkins Hospital, where he ultimately served as an attending physician in the Neurosciences Critical Care Unit for 11 years. He was also founder and past medical director of the hospital's Adult Hydrocephalus Program. He is a widely sought lecturer and educator on the topics of hydrocephalus and ethics.

Dr. Williams is certified by the American Board of Psychiatry and Neurology. He served as chair of the Ethics, Law and Humanities Committee of the American Academy of Neurology from 2003 to 2009. In addition, he is a member of the American Neurological Association and a Delegate to the American Medical Association House of Delegates. Dr. Williams is active on numerous advisory committees and panels with a focus on ethics, organ donation and end-of-life care.

Some of Dr. Williams' most recent articles and presentations relate to interdisciplinary training for end-of-life care, understanding the syndrome of hydrocephalus in young and middle-aged adults, and demonstrating that diagnosing and treating hydrocephalus in the elderly results in significant reductions of Medicare health care expenditures.
