Dr. Gantwerker explains that the training of a neurosurgeon is very long, ten years. He does surgeries on the lumbar, thoracic, cervical spine as well as the brain, including a surgery for epilepsy that has a high success rate. What he really loves is explaining arthritis of the spine to his patients, and giving patients confidence when they’re scared by something like a blood clot in the brain, which he says is a straight-forward procedure.
