    Jocelyn Jiao, MD MS

    Clinical Assistant Professor, Adult Neurology
    Clinical Assistant Professor, Medicine - Primary Care and Population Health

    BioDr. Jiao is a fellowship-trained, board-certified neurologist with the Movement Disorders Center at Stanford Health Care. She is also a clinical assistant professor in the Department of Neurology and Neurological Sciences.

    Dr. Jiao has extensive experience providing comprehensive care for patients with different types of movement disorders, including Parkinson’s disease. She is fellowship-trained in both movement disorders and hospice and palliative medicine. Dr. Jiao is developing an interdisciplinary neuropalliative clinic that emphasizes planning for the future and maximizes quality of life for people living with chronic neurological illness.

    Dr. Jiao’s research efforts include a pilot study assessing the impact of deep brain stimulation (DBS) as a treatment for Parkinson’s-related motor symptoms upon mood and pain. Specifically, this work focuses on identifying correlations between DBS targets and reductions in medications that address depression, anxiety, and impulsivity symptoms that result from Parkinson’s treatments. Dr. Jiao has also completed a pilot study focused upon narrative medicine interventions for people living with Parkinson’s disease.

    Dr. Jiao has published her work in multiple peer-reviewed journals, including Pain Medicine and the Journal of Neurosurgery.
