Dr. Andermann is a Professor in the Departments of Neurology and Neurosurgery, and Pediatrics at McGill University.  He is also the Director of the Epilepsy Service and the Epilepsy Unit at the Montreal Neurological Institute and Hospital. Dr. Andermann is one of the world’s foremost leaders in the description, diagnosis and treatment of epilepsy.  He has shown a remarkable ability to identify syndromes and assemble multidisciplinary teams of researchers to conduct further clinical investigations.  The results of his inquiries in such areas as cortical dysplasias, progressive myoclonic epilepsies, epilepsy surgery and genetically determined disorders have been published in six books and over 500 articles.  His monographs on alternating hemiplegia, Rasmussen’s Syndrome and migraine-epilepsy syndromes have contributed significantly to understanding these disorders and have led to further research in these areas.  Much of Dr. Andermann’s pioneering investigations into epilepsy have been in collaboration with his wife and colleague, Dr. Eva Andermann. They are best known for identifying in the 1970s what later came to be known as Andermann’s syndrome, a debilitating and degenerative disease of the nervous system concentrated in patients of the Saguenay and Charlevoix regions of Quebec.

Dr. Andermann has been a key figure in training neurologists and in the development of epilepsy programs around the world.  Through his vision and leadership, he has expanded his sphere of expertise by gathering around him a strong group of colleagues at the MNI that provide a rich multidisciplinary environment.  Dr. Andermann’s reputation and the environment he has built at the Neuro with Dr. Eva Andermann, have attracted fellows from around the world.  He has trained fellows from more than 15 countries, many of whom have gone on to distinguished academic careers at Harvard University, University of Melbourne, University College Hospitals in London and Tokyo Women’s Medical College.

Dr. Andermann has been recognized for his outstanding achievements with the 2003 Prix Wilder Penfield, the 2000 William G. Lennox Award from the American Epilepsy Society, the 1999 Penfield Award for Contribution in Outstanding Canadian Epileptology from the Canadian League Against Epilepsy, and the 1995 Distinguished Clinical Investigator Award from the American Epilepsy Society and Milken Foundation.  The University of Chicago has created The Fred Andermann and Pierre Gloor Award of Excellence in Clinical Neuro-physiology to be bestowed on an individual for his or her outstanding performance in clinical neurophysiology.  In 2006 he was named Officer of the Order of Canada for his work in the field of health care and in 2007 he was awarded the Peter Emil Becker Prize.

Laurie Ozelius, PhD earned her Bachelor’s degree in biology from Brown University in 1984, and went on to receive a PhD in Genetics from Harvard Medical School (HMS) in 1994. She did her graduate and postdoctoral training in the lab of Xandra Breakefield, PhD, at Massachusetts General Hospital. In 1996, she joined the staff at Mass General as an instructor in neurology working in the Molecular Neurogenetics Unit under the direction of James Gusella, PhD.
In 1998, Dr. Ozelius became an Assistant Professor at HMS, and then moved to the Albert Einstein College of Medicine in New York, where she rose to the rank of Associate Professor of Molecular Genetics. In 2007 she became an Associate Professor in Genetics and Genomics Sciences and Neurology at Icahn School of Medicine at Mount Sinai in New York, where she also held the Bachmann Strauss Chair in Movement Disorders. She returned to Boston in 2015, as an Associate Professor of Neurology at HMS and an Associate Neuroscientist at Massachusetts General Hospital.
Dr. Ozelius works to uncover genetic causes for movement disorders, especially dystonias and Parkinson’s disease. In 1997, Ozelius and colleagues identified the first genetic cause for an isolated inherited dystonia, when they found mutations in the DYT1 (TOR1A) gene in patients with early onset isolated dystonia. She has also shown that variants within TOR1A are associated with the reduced penetrance of this disorder. Subsequent work uncovered two additional genes for isolated dystonia (THAP1 and GNAL), and a gene for rapid onset dystonia parkinsonism (ATP1A3).
The Ozelius laboratory also played a central role in identifying the G2019S LRRK2 gene mutation as a major cause of Parkinson’s disease in the Ashkenazi Jewish population.
Dr. Ozelius collaborates with movement disorder clinicians worldwide to collect and characterize patients and families with various inherited dystonias and other movement disorders. Her lab applies several genetic strategies, including genome-wide association studies and next-generation sequencing to identify new genes and risk factors involved in these diseases. Her work is helping to clarify the underlying mechanisms and basic pathophysiology of dystonias and PD, providing a foundation for better diagnosis and effective treatments.

Dr Yano completed his MD at the University of Chicago Pritzker School of Medicine with a PhD in molecular genetics and cell biology studying an inhibitor of DNA replication in bacteria.  He remained at the University of Chicago Comer Children’s Hospital to complete his training as a pediatric neurology fellow.

In August 2015, at the 4th ATP1A3 Symposium in Bethesda MD.  Dr Yano presented an abstract and did an oral presentation on a new phenotype of the ATP1A3 mutation which has since been published. In collaboration with Dr. Silver and other physicians, he identified a group of people who have ATP1A3 mutations that cause a new syndrome, ‘fever-induced paroxysmal weakness and encephalopathy.’ These children have episodes of weakness and other neurological symptoms triggered by fevers and can take months to recover.
