Paul S. Fishman M.D., Ph.D. is Professor of Neurology, Adjunct Professor of Pharmacology and Neurobiology at the University of Maryland School of Medicine, and Chief of Neurology for the Maryland VA Health Care System.
With dual training in neuroscience and neurology his main research interest is the translation of novel therapies for neurodegenerative diseases such as Parkinson’s disease, Alzheimer’s disease (AD), and ALS. As a clinician he established the first Alzheimer’s clinical program at the School of Medicine and has been an active participant in experimental drug trials for AD. He is the founder of the Medical-Scientific Board of the Alzheimer’s Association of Greater Maryland and has served on their Board of Directors. His laboratory explored the role of mitochondrial dysfunction in cellular and animal models of AD. He founded the program for the treatment of movement disorders with botulinum neurotoxin at Maryland while his laboratory developed strategies for detection and reversal of the toxin. He has a longstanding interest in the biology and potential therapeutic use of tetanus toxin as an enhancer of inadequate motor neuron activity, and of its non-toxin peptides as delivery vectors into the nervous system for therapeutic enzymes and trophic factors. He is the co-founder of the joint Neurology-Neurosurgery Deep Brain Stimulation (DBS) program at Maryland for the treatment of movement disorders, as the intra-operative neurologist and as leader of the group that programs the devices.
His recent clinical and basic research involves the therapeutic use of focused ultrasound (FUS) in the brain. He a member of the FUS Center of Excellence at Maryland, and is the Neurology arm of the team instrumental to the first FDA approval of this technology in the brain for treatment of essential tremor. Current studies with patients with Parkinson’s disease explore this technology as a less invasive alternative to DBS. His basic research utilizes this technology to open the blood-brain barrier for delivery of cellular and molecular therapeutics for neurodegenerative disease. With collaborators in Radiology and Pharmacology they have combined FUS with magnetic attraction or iron containing nanoparticles to enhance minimally invasive stem cell delivery to the brain.
Dr. Fishman is a member of the American Neurological Association, the American Academy of Neurology, listed in Best Doctors in America, and past Chair of the Parkinson’s Disease Research Review Group for the VA. He is past Chair of the University of Maryland IRB and the School of Medicine Promotions Committee, and past member of the University Faculty Senate, School of Medicine Executive Committee, and University Medical Center Executive Committee. He is a founding member of the Stem Cell Consortium of the School of Medicine. He is a current research grant reviewer for the NIH, VA, FDA and FUS Foundation. He has over 100 peer reviewed publications and current funding from the VA and the FUS Foundation.
