Andrew G. Parrent, MD, FRCSC
Associate Professor of Neurosurgery, Western University
Office: London Health Sciences Centre, University Hospital B10-134
Secretary: Waheeda Abrahim
Dr. Parrent received his B.Sc from Brock University in St. Catharines and his MD from the University of Toronto in 1983. He completed a neurosurgery residency at Dalhousie University in Halifax and a two-year fellowship in Sterotaxic/Functional Neurosurgery at The Toronto Hospital.
Dr. Parrent is Assistant Professor of Neurosurgery at Western University and Associate Scientist at Robart's Research Institute in London. He is conducting research in collaboration with Terri Peters of the Robart's Institute to establish a computer based image guided surgical planning system for neurosurgical procedures. He has also developed an interactive video CD for teaching surgical techniques to residents.
Dr. Parrent has contributed to many medical textbooks and has been published in numerous journals including the New England Journal of Medicine and Canadian Journal of Neurological Sciences.
Dr. Parrent's research focuses on minimally invasive techniques for the surgical treatment of epilepsy. He has published research on sterotactic surgery techniques for the treatment of temporal lobe epilepsy. He is undergoing research in brain stimulation on the temporal lobe for the purpose of treating temporal lobe seizures with electrical simulation rather than with surgical procedures. His clinical research focuses on endoscopic surgery and image-guided surgery.
