Dr. Friedman is an expert in adult and pediatric movement disorders and has particular interest in genetic and metabolic disorders that affect movement. She directs the Movement Disorders and Tourette/Tic Disorder Clinics at Rady Children’s Hospital and does research in the areas of neurogenetics, Tourette’s Syndrome and disability awareness education. In addition, she teaches medical students residents, fellows, and undergraduate students.

Dr. Friedman received her undergraduate training at Princeton University and earned her MD from Stanford University in 1991. She completed an internship in internal medicine at Santa Clara Valley Medical Center followed by residency in neurology at Harvard Longwood Training Program. She was a clinical fellow in movement disorders at Boston University Medical Center and a clinical and research fellow in neurogenetics and dystonia at Massachusetts General Hospital.

She served as a neurologist at several Boston hospitals and was an instructor in neurology at Harvard Medical School before joining Rady Children’s Hospital in San Diego as senior staff neurologist in 2004.

Dr. Friedman also serves as clinical professor in the UC San Diego Departments of Neurosciences and Pediatrics. Dr. Friedman is a diplomate of the American Board of Psychiatry and Neurology. She is a member of the American Academy of Neurology, the Movement Disorder Society, the Tourette Syndrome Association, and the Phi Beta Kappa National Honor Society.

Dr. Friedman developed and runs the Rady Children’s Hospital Movement Disorder and Tic/Tourette’s Clinic and is the only pediatric movement disorders specialist in San Diego. Dr. Friedman treats patients with a wide range of movement disorders including: tics/Tourette, dystonia, myoclonus, chorea, stereotypy, tremor, ataxia, periodic paralysis, paroxysmal dyskinesia, restless legs, and hyperekplexia. She is an expert on neurogenetic disorders and disorders of neurotransmitter synthesis and consults on cases throughout California, nationally and internationally.
Dr. Friedman’s research interests include neuro-metabolic and genetic disorders that affect movement. She has particular interest in efforts to better understand and treat pediatric neurotransmitter disorders. She recently directed an international collaboration to characterize sepiapterin reductase deficiency, a form of dopa-responsive dystonia and participated in research efforts involving the use of fMRI to better understand the brain mechanisms that underlie behavioral therapy for tics (CBIT). She conducts research involving the use of exome sequencing to diagnose rare disease. She also conducts research and training on disability awareness education (see service below)
Dr Friedman is a strong proponent of education of children to improve understanding of and tolerance toward those with disabilities. In 2005, in partnership with the Del Mar Heights Elementary School, Dr. Friedman developed the Understanding Differences program a curriculum designed to teach K-6 children tolerance through a basic understanding of the biology of disease and disability and environmentally related factors that affect health and wellness. Dr. Friedman continues to run this program which has been awarded the 2008-2009 Program Award of Excellence award from the North Coastal County PTA as well as the 2010 California School Board Golden Bell Award.
