Penelope Hogarth M.D.

Director of clinical research: Dr. Penny Hogarth joined the OHSU movement disorders faculty in 2000 and is currently an associate professor of neurology. She holds a joint appointment as clinician scientist at the VA Medical Center and a joint appointment in the department of genetics. Dr. Hogarth’s research interests have focused on deep brain stimulation for Parkinson's disease and the natural history of Huntington’s disease. She heads up the DBS cooperative study comparing best medical management versus stimulation of subthalamic nucleus and globus pallidus for the treatment of Parkinson's disease. She is also part of the Huntington’s study group and is interested in novel therapies for Huntington’s disease. Dr. Hogarth is an expert clinician in all movement disorders with a special interest in Huntington’s disease.
