Richard Lewis, MD, FAAN
Director, EMG Laboratory
Co-Director, Neuromuscular Clinic
Richard Lewis, MD, FAAN is Director of the EMG (electromyography) Laboratory and Co-Director of the Neuromuscular Clinic in Cedars-Sinai’s Department of Neurology at Cedars-Sinai. He is board certified in neurology, electrodiagnostic and psychiatric medicine.
Dr. Lewis research and clinical focus is on neuromuscular disease, including inflammatory neuropathies, myasthenia gravis, gene therapy for motor neuron diseases and muscular dystrophy. He is well known for his expertise in caring for and developing new diagnostic and treatment approaches to neuromuscular disorders, including amyotrophic lateral disease (ALS). He has earned world-wide recognition for his research on multifocal demyelinating neuropathy, commonly known as Lewis-Sumner syndrome, a variant of chronic inflammatory demyelinating polyneuropathy (CIDP), thought of as the long-lasting version of Guillain-Barré syndrome. Guillain-Barré is characterized by acute progressive paralysis, with symptoms typically improving over weeks or months. CIDP and Lewis-Sumner syndrome are chronic disorders that require on-going treatments to prevent loss of function.
Dr. Lewis has published more than 50 articles in peer reviewed journals and sits on the editorial board of the Journal of Neuropathic Sciences, the Journal of Neuropathic Pain, Muscle and Nerve and the Journal of Neuromuscular Disorders. In addition to the more than 90 abstracts and presentations delivered at association meetings, Dr. Lewis has lectured both nationally and internationally on neuropathies and associated conditions. He has also published numerous reviews, chapters and opinion papers.
Dr. Lewis is an elected member of the board of directors of several major professional societies, including the American Neurological Association, the World Federation of Neurology ALS Consortium, the Inflammatory Neuropathy Consortium, the Peripheral Nerve Clinical Trials Group Steering Committee and the American Society of Neuroimaging. He is a fellow of the American Academy of Neurology, a member of the American Association of Neuromuscular and Electrodiagnostic Medicine, the Peripheral Nerve Society and serves on committees and advisory boards for these organizations.
After earning his bachelor’s degree at Union College in Schenectady, New York, Dr. Lewis earned his medical degree at the Medical College of Virginia in Richmond. He performed a rotating internship at Hartford Hospital in Connecticut and a residency in neurology at the Hospital of the University of Philadelphia in Pennsylvania. He continued his postgraduate training, performing a fellowship in electromyography at Pennsylvania Hospital in Philadelphia.
Before joining Cedars-Sinai, Dr. Lewis was Vice Chief of Neurology and Director of Clinical Neurophysiology at Harper University Hospital in Detroit. He was Professor and Associate Chair of Neurology at Wayne State University School of Medicine, where he directed the Hiller Amyotrophic Lateral Sclerosis Center, Co-director of the Muscular Dystrophy Association Clinic at Detroit Medical Center and Director of the Inflammatory Neuropathy Center of Excellence.
