  • Dr. Kevin Duff is a board certified Clinical Neuropsychologist. He conducts comprehensive neuropsychological evaluations in the Cognitive Disorders Clinic, a sub-specialty clinic of the University of Utah Center for Alzheimer’s Care, Imaging and Research (CACIR). These evaluations are key to definitively diagnosing memory disorders such as Alzheimer's disease and dementia. Dr. Duff’s clinical interests focus on a wide range of neurodegenerative disorders, from Mild Cognitive Impairment and Alzheimer’s disease to Huntington’s disease.

    Dr. Duff also conducts extensive research in clinical neuropsychology, aging and dementia. His current research, which has been funded by the NIH, examines the role of practice effects in predicting dementia.
