“The results of this study suggest that some individuals with a history of TBI are at risk for late-life neurodegeneration but not Alzheimer’s disease,” says Kristen Dams-O’Connor, PhD, Co-Director of the Brian Injury Research Center and Associate Professor in the Department of Rehabilitative Medicine at the Icahn School of Medicine at Mount Sinai. “We want to identify and treat post-TBI neurodegeneration while people are still alive, but to do this, we need to first understand the disease. Prospective TBI brain donation studies can help us characterize post-TBI neurodegeneration, identify risk factors, and develop effective treatments.”
These findings suggest that clinicians may be misdiagnosing late-life TBI-related neurodegeneration as Alzheimer’s disease, and therefore treatment targeting Alzheimer’s would be ineffective in helping late-life decline among patients who experienced TBI. Further work is needed to characterize post-TBI neurodegeneration.

The Mount Sinai Health System is an integrated health system committed to providing distinguished care, conducting transformative research, and advancing biomedical education. Structured around seven hospital campuses and a single medical school, the Health System has an extensive ambulatory network and a range of inpatient and outpatient services—from community-based facilities to tertiary and quaternary care.
The System includes approximately 7,000 primary and specialty care physicians; 12 joint-venture ambulatory surgery centers; more than 140 ambulatory practices throughout the five boroughs of New York City, Westchester, Long Island, and Florida; and 31 affiliated community health centers. Physicians are affiliated with the renowned Icahn School of Medicine at Mount Sinai, which is ranked among the highest in the nation in National Institutes of Health funding per investigator. The Mount Sinai Hospital is ranked as one of the nation’s top 10 hospitals in Geriatrics, Cardiology/Heart Surgery, and Gastroenterology, and is in the top 25 in five other specialties in the 2014-2015 “Best Hospitals” issue of U.S. News & World Report. Mount Sinai’s Kravis Children’s Hospital also is ranked in seven out of ten pediatric specialties by U.S. News & World Report. The New York Eye and Ear Infirmary of Mount Sinai is ranked 11th nationally for Ophthalmology, while Mount Sinai Beth Israel is ranked regionally.
