Meet the Team

Dr. Mastrianni is an expert in memory disorders and other neurodegenerative conditions. He received his neurological training at the University of Pennsylvania and completed a postdoctoral research fellowship at UCSF, where he studied the molecular genetics of prion disease in the laboratory of Stanley Prusiner during the time he won the Nobel Prize for his work on prions. He and his team of neurologists, neuropsychologists, geriatricians, nurses, psychiatrists, and social workers provide comprehensive diagnostic evaluations and long-term management of patients with Alzheimer’s disease and related dementias, especially atypical dementia and younger-onset Alzheimer’s Disease. He also conducts clinical and basic science research aimed to better understand and treat neurodegenerative diseases. As Director of the Behavioral Neurology and Neuropsychiatry Fellowship program at UChicago, he guides the training of neurologists who will be our future specialists in dementia. 

Dr. Mastrianni’s special interests include early onset Alzheimer’s disease and atypical forms of dementia. His research is aimed at understanding neurodegenerative disease, in particular, the prion diseases. These unusual disorders have many similarities with Alzheimer’s and other neurodegenerative diseases. Another focus of Dr. Mastrianni is the use of specialized brain imaging techniques to diagnose Alzheimer’s disease far in advance of obvious clinical signs.

An accomplished author, Dr. Mastrianni has published more than 60 scientific articles, book chapters, and medical reviews related to dementia. He has served on a Scientific Advisory Panel of the FDA, the Medical and Scientific Advisory Committee of the Alzheimer’s Association, the ECRI Institute of the U.S. Agency for Health Care Research and Quality, and he is a consultant for the U.S. Federal Trade Commission and CVS Caremark, among others. His research has been supported by the National Institutes of Health (NIH), the Howard Hughes Medical Institute, and the Alzheimer’s Association, in addition to several foundations. He is also the recipient of many awards and honors such as the Frederic A. Gibbs Discovery Award for Scientific Achievement from the Brain Research Foundation.
