Kevin Duff, Ph.D., ABPP-CN

  • Professor of Neurology, School of Medicine

Biography

Dr. Kevin Duff specializes in neuropsychology at OHSU's Oregon Alzheimer's Disease Research Center to try and help patients with brain diseases appreciate the strengths and weaknesses in their thinking skills. Although much of his practice focuses on working with older adults, he sees patients ages 18+. In addition to evaluating patients and their thinking skills, he does research on cognitive disorders in later life (e.g., Alzheimer’s disease), including how we best diagnose and treat these conditions.

Dr. Duff is a recent transplant to Oregon after spending 13 years practicing in Utah. When not at work, he spends time with his family learning about their beautiful new surroundings in the Pacific Northwest.
