Jessica de Leon, MD

Assistant Adjunct Professor
Neurology

Dr. Jessica de Leon received her undergraduate degrees in neuroscience and Spanish at Johns Hopkins University and an MD with thesis degree at UCSF. She then completed a medicine internship and neurology residency at UCSF, where she served as chief resident. She completed a fellowship in behavioral neurology and is currently an assistant professor at the UCSF Memory and Aging Center (MAC). Her research focuses on how bilingualism, language typology, and genetics affect the symptoms, neuroimaging, and progression of primary progressive aphasia and related neurodegenerative disorders.
