Yvette Bordelon, MD, PhD, and Carlos Portera-Cailliau, MD, PhD

The Guest Editors of this issue of Seminars in Neurology are Drs. Yvette Bordelon and Carlos Portera-Cailliau. They are a husband and wife team of movement disorder physicians at the University of California Los Angeles.

Dr. Bordelon is an Associate Clinical Professor of Neurology at UCLA Medical Center. She earned her Bachelor of Science degree from Louisiana State University, graduating summa cum laude and Phi Beta Kappa. She received her MD/PhD training at the University of Pennsylvania, and stayed at Penn for her internship in internal medicine. She trained in neurology at the Massachusetts General Hospital/Brigham and Women's Hospital Residency at Harvard Medical School, where she became chief resident. She subsequently was a fellow in movement disorders at Columbia University. She then joined the faculty at the University of California, Los Angeles, rising to the rank of Associate Professor in 2013. Dr. Bordelon has had an outstanding scientific and clinical career, is considered a true expert in Parkinson disease, and has a particular interest in atypical parkinsonian disorders. As one of my former trainees, she is undoubtedly one of the most marvelous physicians with whom I've ever worked, someone who cares deeply for her patients and for the field of movement disorders.

Dr. Portera-Cailliau is an Associate Professor of Neurology and Neurobiology at UCLA. He initially was educated in Spain at the Lycée Français de Madrid, and later attended UC San Diego (Revelle College), where he received a Bachelor of Arts degree and graduated magna cum laude and Phi Beta Kappa. He then attended Johns Hopkins School of Medicine for his MD/PhD in neuroscience. He stayed at Johns Hopkins for his internal medicine year, then trained in neurology at the Massachusetts General Hospital/Brigham and Women's Hospital Residency at Harvard Medical School (where he was also a chief resident), and subsequently did postdoctoral research and clinical fellowships at Columbia University, and a second postdoctoral research fellowship at Cold Spring Harbor Laboratory. He subsequently joined the faculty at the University of California, Los Angeles, where he now codirects the Medical Scientist Training program. His research has focused primarily on studying the underlying synaptic and circuit abnormalities in fragile X syndrome. He has mentored many medical students, residents, and postdoctoral fellows, and has clearly achieved a lofty status in the world of movement disorders research, being considered one of the true experts in the field.

We greatly appreciate the efforts of Drs. Bordelon and Portera-Cailliau, as well as all of their contributing authors, for their great work in this issue of Seminars. The issue provides tremendous insights to atypical movement disorders, enlightening the reader to the nuances of this field, the important steps to date that have been taken to understand the diseases better, and the research being done that will help to improve the care of patients with atypical movement disorders in the future.
