John Nutt M.D.

Co-founder and Director Emeritus of the OHSU Parkinson Center and Movement Disorders Program

Dr. Nutt sees new patients in consultation only. If they wish to continue being seen at the center, he will recommend one of his colleagues to see them on a regular basis.

Dr. Nutt joined the OHSU movement disorders faculty in 1978 and is currently a professor of neurology. He is an expert clinician, scientist and teacher.

Dr. Nutt has gained international recognition for his innovative research in movement disorders and is widely used as a scientific consultant in the development of many new therapeutic agents for Parkinson's disease. He is widely recognized for his work on the pharmacokinetics of levodopa which has provided significant clinical and scientific insight on this important therapy for PD. His background in pharmacology has made him a world leader in testing many novel therapeutics for Parkinson's disease as well as new neuroprotective and neurorestorative therapies. He has also become a world leader and international expert in understanding the gait and balance problems of PD and ways to better manage these problems.

Dr. Nutt is an expert clinician for all movement disorders.
