Raquel Gardner, MD

Assistant Adjunct Professor

As a board-certified neurologist, Dr. Gardner evaluates and treats patients with various neurological disorders and provides them with follow-up care. As a fellowship-trained behavioral neurologist, Dr. Gardner has specific expertise in the evaluation and management of patients with neurodegenerative disorders such as dementia and mild cognitive impairment.

Her research program focuses on understanding the epidemiology and mechanisms of long-term sequelae of traumatic brain injury in older adults with the goal of improving outcomes in this vulnerable population. Her work is supported by the National Institutes of Neurological Disorders and Stroke, the Department of Defense, the American Federation for Aging Research, the Weill Institute for Neurosciences, and the UCSF Research Allocation Program.
