Dr. Oscar Lopez is a neurologist and a professor of Neurology, Psychiatry, and Clinical and Translational Sciences at the University of Pittsburgh School of Medicine.

Dr. Lopez is currently conducting studies, as principal investigator, and co-investigator, of the factors that modulate the transition from normal to MCI and to dementia in relationship to cerebral amyloid deposition. These studies examine how cardiovascular and cerebrovascular factors create a vulnerability state for AD and neurodegeneration, and how they affect physiologically relevant compensatory mechanisms in the brain using MRI, SMBT-1 (inflammation tracer), FDG-PET, Pittsburgh Compound-B (PiB) PET, tau-PET ligand technologies, as well as blood biomarkers.

He has published numerous articles in peer-reviewed journals and is a member of the American Academy of Neurology, the Royal Society of Medicine, the American Neurological Association, the American Society of Behavioral Neurology, and the International Psychogeriatric Association.
