Role of Age, Dopamine, and Tau Related Network Disruption in Setting a Context for Progression Toward Alzheimer's Disease
This project investigates the impact of tau associated with Alzheimer’s disease and of dopaminergic changes in aging on the function of brain networks and associated cognitive abilities. Cognitively normal older adults and individuals diagnosed with Mild Cognitive Impairment undergo MR-PET imaging to measure dopamine and tau levels in the brain, which are examined for relationships to the organization and function of brain networks. To get volunteer for any of these projects, please contact Jacqueline Emerson, Clinical Research Coordinator: Jacqueline.emerson@mssm.edu.
Tau, Amyloid, & White Matter Burden Interact to Impact Brain Networks in Preclinical Alzheimer’s disease
This project investigates the regional impact of tau and amyloid associated with Alzheimer’s disease and of white matter damage of presumed vascular origin on the function of brain networks and associated cognitive abilities. We use MR-PET imaging to measure amyloid and tau in the brains of cognitively normal older adults and examine relationships to the architecture of brain networks that undergird cognitive function.

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Below are financial relationships with industry reported by Dr. Hedden III during 2022 and/or 2023. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
