Study Summary

COPD is the third leading cause of combined morbidity, disability, and mortality in the United States and is often associated with cognitive impairment. The goal of the proposed project is to examine novel pulmonary and vascular physiological mechanisms that contribute to structural brain abnormalities and cognitive dysfunction early in the course of COPD. The project will generate information to ultimately inform the development of interventions to delay or prevent cognitive dysfunction.
