As the director of the Johns Hopkins Parkinson’s Disease and Movement Disorders Center, Dr. Zoltan Mari's clinical practice focuses on movement disorders, including Parkinson's disease and related syndromes, essential tremor and dystonia, with particular interest in deep brain stimulation (DBS) therapy and botulinum toxin injections for sialorrhea (drooling or excessive salivation). His clinical interests also include clinical neurophysiology, including nerve conduction/electromyography and intra-operative monitoring.
Zoltan Mari, M.D., graduated first in his Medical School class at the University of Szeged, Hungary. His training includes residency in neurology (SUNY Downstate, Brooklyn, NY), fellowship in movement disorders and clinical neurophysiology with EMG emphasis (both at NIH, Bethesda, MD), and Clinical Research Curriculum Certificate (NIH). He is board certified in neurology and clinical neurophysiology by ABPN. During his senior fellowship years Dr. Mari served as Director of the NIH Botulinum Toxin Clinic and was featured in CBSs 60 minutes, as the injector of the pianist Leon Fleisher. Dr. Mari received travel awards from the AAN and ANA during his training years.

Research & Publications
Dr. Mari is a team member of the Johns Hopkins Morris K. Udall Parkinson's Disease Research Center of Excellence where he reviews all charts and sees all patients enrolled in the Longitudinal Study at the Udall Center. He is the senior author of a research effort titled “Factors Associated with Falls in Parkinson's Disease”, a project that made use of the Longitudinal Dataset acquired as part of the main clinical research activities at Udall Center and was recently accepted as an abstract publication to the 15th International Congress of Parkinson’s Disease and Movement Disorders.
Dr Mari's research focuses on clinical trials in Parkinson’s disease modification and neuroprotection, and the neurophysiology of and motor control in movement disorders, with particular interest in basal ganglia pathophysiology in dystonia. In his leadership of the Deep Brain Stimulation Program at Johns Hopkins Hospital he has been the principal investigator on multiple major NIH-funded clinical trials on neuroprotection in Parkinson disease, including the NET-PD and QEIII trials (to investigate the possible disease modifying effect of creatine and Coenzyme Q10, respectively).
Clinical Trial KeywordsBotulinum toxin type B injection in the treatment of sialorrhea (drooling or excessive salivation), movement disorders, Parkinson's disease, neuroprotection
