A University of Pittsburgh and UPMC research team reported an inflammatory lung–vascular–brain axis that may explain why people with pulmonary hypertension experience cognitive decline. Using multimodal methods—brain MRI, blood-based molecular profiling, and mouse functional studies—the group tied specific brain abnormalities to inflammatory processes operating in the lungs and heart. The investigators published findings in the Journal of Clinical Investigation describing cerebellar and frontal lobe alterations in pulmonary hypertension that implicate the shared inflammatory mechanism. Research lead Stephen Chan, MD, PhD, said cognitive symptoms in pulmonary hypertension are not merely secondary issues but may reflect part of the disease process. The work also connects earlier genetic findings to the broader biology, including the role of an NCOA7 variant present in roughly a quarter of patients, which is associated with heightened inflammatory responses and worse survival odds. The study points to neural targets that could shape future diagnosis, prognosis, and therapeutic strategies.
