Neurological Surgery
Michael Kaplitt

Michael Kaplitt, PhD, MD specializes in neurosurgical treatment of movement disorders, including Parkinson's disease, essential tremor and dystonia, using various surgical approaches including deep brain stimulation. He also specializes in surgery for intractable pain and spasticity, implanting devices such as spinal cord stimulators and spinal infusion pumps. He is also an expert in the treatment of trigeminal neuralgia and hydrocephalus, and perfroms general neurosurgery as well. He works with a team of specialists, including neurologists, neurophysiologists, neuropsychologists, brain imaging experts, physiatrists/therapists, and pain management specialists to provide superior care in all of these areas before, during and after surgery. Dr. Kaplitt is also an internationally recognized expert in gene therapy and molecular neurobiology, and he is a leading figure in the development of new technologies for improving or restoring brain function.

Michael Kaplitt graduated Magna Cum Laude from Princeton University in 1987 with a degree in Molecular Biology and Russian Studies. He enrolled in the Tri-Institutional M.D.-Ph.D. Program and received his Ph.D. in Molecular Neurobiology in 1993 from The Rockefeller University and his M.D. in 1995 from Cornell Medical College. Following his Neurosurgery residency and chief residency at Cornell, he completed a fellowship in Stereotactic and Functional Neurosurgery with Dr. Andres Lozano at the University of Toronto prior to joining our staff as Assistant Professor of Neurological Surgery in July 2001.

His clinical activities focus upon using minimally invasive, stereotactic techniques for the treatment of functional disorders such as Parkinson's disease, essential tremor and epilepsy. He also uses surgical methods to implant devices such as spinal cord stimulators and opiate pumps to treat complex pain, and he is also an expert in the treatment of trigeminal neuralgia and hydrocephalus. Dr. Kaplitt has pioneered the use of gene therapy in the brain. He has published over 40 papers and has edited two books on this subject. He recently completed the first clinical trial of gene therapy for Parkinson's Disease for FDA approval, and his laboratory is actively researching mechanisms of cell death in diseases such as Parkinson's and Huntington's. Dr. Kaplitt is the recipient of numerous awards, including the Young Investigator Award from the American Society for Gene Therapy and he was named to Crain's 40 under 40 list for 2004.

He currently serves on the editorial boards of several journals, and is Editor of the World Society for Stereotactic and Functional Neurosurgery Web Site. He is also a member of the Weill Cornell Medical School Committee on Admissions. He is also Adjunct Assistant Professor at The Rockefeller University and Clinical Assistant Surgeon at Memorial Sloan-Kettering Cancer Center.
